Pending cost of FAA mandates for legacy aircraft

Lower costs are nice, but in the end, think it’s more of a lack of interest coupled with high fuel and powerplant/maintenance costs that is driving decline of GA. Coupled with continual loss of airports at the periphery of the country; the middle seems a bit better in this regard.
Lower costs are going to be the DRIVING FORCE in GA. Lack of interest is due to a $20k initial investment and a $200-300 hour rental rate. And close to $2k a month if ownership is considered.

We are losing airports because the airports are not driving any revenue into the local coffers. Make airports valuable and they'll stop disappearing. How? Increase usage. How? Lower the cost of flying. See how that works?

Car motors are are the only viable way forward. No, not $50k installs. E/ABs needs motors at the sub $10k level FWF. I honestly don't care about the certificated world. Even if the perfect car motor descended from heaven having been created by the heavenly father himself and landed at current day Moses's feet some rando's gonna post about how its not as good as a motor designed 50-70 years ago.

An d I have told you before: that aircraft engine crank has to be re-nitrided after grinding. Nitriding increases strength and wear resistance. And nitriding isn't cheap, and there are few places that do it. The grinding is only a small part of the cost.

I have thousands of hours grinding cranks.

The Lycoming iE2 is an electronically-controlled engine and has EFI and EI. For certification it had to have redundant electrical supply, as that is the most common form of electrical failure. The electronics themselves also much have some redundancy. Car engines have no redundancy; when their electronics fail, they coast to the side of the highway. When an auto conversion's electronics fail in an airplane, it coasts at considerable speed to the crash site. So the builder should incorporate some redundancy; how many are capable of that?

I installed a Subaru conversion in a Glastar. It had no redundant systems AT ALL other than a second electric fuel pump. That's what the owner wanted. I flew it, knowing that if anything failed, I was going to land unwillingly, but that area was nothing but relatively flat farm fields and straight country roads. I would not have flown it into the mountains.
Cast iron car cranks are not nitrided. And if I wanted to nitride a forged crank, with grinding its maybe $800-ish. Since a car motor should not see more than 4500-5000 rpm (bearing speeds be a thing yo) nitriding is not required.

"Upgrading to a nitrided forged steel crank in a sub-5,000 RPM, naturally aspirated engine is usually an unnecessary expense. The engine will not realize the benefits of the forged steel's fatigue resistance or the nitriding's extreme hardness because the engine simply isn't being pushed hard enough to stress the cast iron."

I honestly can't believe that the old 'car motors have no redundency'. Is that old wives tale still a thing? I'll put an EFI up against mags any day of the week.

Cool Subaru story, bro. Gee, how many certified engines magically stop and end up in fields? That somehow doesn't factor in? I mean you have TWO farm tractor magnetos and can still go off airport LOL. Seriously, is that the best counter you have to a car motor? 'I felt scared becuase I didn't have a second tractor magneto'?

Man these old wives tales just will. not. die.
 
You said this:
The machining cost to grind a airplane crank and a car crank are exactly the same. The liability and paperwork is the difference.
And I said this:
An d I have told you before: that aircraft engine crank has to be re-nitrided after grinding. Nitriding increases strength and wear resistance. And nitriding isn't cheap, and there are few places that do it. The grinding is only a small part of the cost.

And then you come back with this:

Cast iron car cranks are not nitrided. And if I wanted to nitride a forged crank, with grinding its maybe $800-ish. Since a car motor should not see more than 4500-5000 rpm (bearing speeds be a thing yo) nitriding is not required.
And:
"Upgrading to a nitrided forged steel crank in a sub-5,000 RPM, naturally aspirated engine is usually an unnecessary expense. The engine will not realize the benefits of the forged steel's fatigue resistance or the nitriding's extreme hardness because the engine simply isn't being pushed hard enough to stress the cast iron."
Both of which are just deflecting. We were not talking about nitriding car cranks. Why do you constantly move the goalposts?

I mean you have TWO farm tractor magnetos and can still go off airport LOL.
Properly maintained magnetos are much safer than the EFI, since that EFI relies on the electrical system for survival. And since 90% of performance problems are electrical, we need redundancy for those systems.

You are going learn some stuff the hard way, or not at all.
 
I disagree. That may be a 50% discount from 'current' prices, but that still puts flying out of the grasp of most people.

Recreational flying has always been an expensive hobby.
The cost would have to be sub-$100k for 4 place 120kt airplane. Amortize a $200k note and then look at current median income. On top of that airport space and mechanic availability and parts.
No way would we ever see a sub $100k 4 place airplane. At least not one anyone would want to get in.
Flying is either an elite hobby or a career path. What other 'hobbies' have a $10-20k entry fee (certificate) then $200-400k equipment buy in (sans renting or a club)?

I spent several years in motor yachting. You think aviation is expensive...................

But even in that people would buy in to something they can't afford, then be shocked at what it cost to maintain. Ever call out a marine technician to your dock for service? Their rates make a GA Maintenance shop look downright cheap.

Dock fees, Insurance, Zinc replacements, haul outs for bottom paint, fuel (again, think avgas is expensive?) it all adds up. This is why there are so many derelicts sitting around marinas, the owners run out of fun and money at the same time.
You do have toys like the SE-1 that are sub $100k but its quite literally a toy. Other than shiny metal you can get into a single seat put put for way less.

Like previously stated, it feels a niche much like the guys that own and ride Harleys.
The FAA could do two things to make flying affordable: allow certificated planes a one time move into E/AB or like in Canada a sort of 'owner maintenance' (once in, you never, ever go back to certified). That opens up the parts and the motors to more sane options and costs.

It's not the FAA. It's a dying market. I started out flying in the 70's when airplanes were being produced by the thousands, airports were busy and GA was booming. That started dying out in the early 80's and never recovered.
Two: allow AnP's to do Annual inspections. Allowing an AnP to sign off a 100hr but not an annual artificially shrinks the pool of bodies that can do the inspection.
Nope.

Back in the day the FAA regulated the number in the IA pool and the quality was good. Getting an IA was a 10 question essay style test that took much of a day to complete and many didn't pass. It was also difficult to get selected to test.

Then people complained the test was "too subjective" and lobby for an easier test, so the FAA went to a 50 question multiple choice test that anyone with an A&P with 3 years could take. The IA ranks were then flooded by people who were clueless and more than happy to sell their signatures for a few bucks. Now we have airports full of maintenance neglected airplanes that are the cheap owners pride and joy.

Lowering standards never improves quality.

What is the mean time between failure for a modern automotive EI vs. a standard aircraft magneto, or auto EFI vs. aircraft carburetor? I mean real data, not guesses.

It's not the EI or EFI so much that fails. It's the electrical system that supplies the power to those things. Alternators are famously neglected; we regularly read reports here of alternators that failed in flight and stranded the airplane in some inconvenient spot. When we point out that the alternator manufacturers (and some of the airframe manufacturers too) recommend 500-hour inspections of the brushes, the weak point in those things, owners just laugh and say "If it ain't broke, don't fix it." So they run it until it does fail, and regret it. Learning stuff the hard way. Same goes for vacuum pumps. And magnetos. Those things do wear and could fail at a bad time if their periodic inspections aren't done.

Carburetors? Mostly last forever, certainly through a TBO period. The Bendix/Stromberg carb on my A-65 was still running and working fine after 70 years. Some might need rubber parts after so many years, but the rubber-tipped float needle in mine was still fine.

Tried to look at this...interesting results.

My database of homebuilt accidents from 1998 through 2024 shows 41 accidents where the failure of a magneto system was a factor, and 62 accidents where the failure of an electronic ignition system was involved. The latter includes cases where the actual failure was in providing power to the EI system.

Median time to failure for magneto systems: 93 hours
Median time to failure for electronic ignitions: 207 hours

This, of course, doesn't take into account the number of systems that DIDN'T fail. But it does look like that, if a magneto is going to fail, it's going to fail earlier.

Don't have any easily-extractable data on EFI vs. carburetor.

Okay. So given this project was developed enough to determine certification costs per unit, at what point during the STC certification plan (PSCP) did the FAA project manager discontinue the process on the V8?
Not sure why you continue to be so interested in our projects points of failure but I’ll end the topic here as its irrelevant to everyone else… also recommend you read the website as it details what you continue to inquire about.

The project was going exceptionally well at MIDO and ACO levels, in fact they were encouraging. The issues happened at policy level and executive levels made it clear to all they didn’t want it and the word spread it seemed to all cert levels within the FAA. First off, understand there is no requirement for a project of this level to hire DERs, and applicant can deal directly with ACO (called that at the time) which was necessary to reduce costs to make it work. But, this became impossible when FAA took literally years to respond to us, at all levels. I expect even if we had hired the different categories of DERs it would not have been super easy but it would have forced them to respond to delegated reps . Our tem included former DER and engineers and the cert plan and basis was not over technical…..remember these planes were certified in the 1950s under CAR. But paying DERs, would need at least 3 in different specialist, to argue and negotiate would have bankrupted us before we could get going. It was a lose -lose proposition….likely our best bet was to hire a lawyer and threaten to sue them to simply do their job, but that would require an open check book.

Remember, we had a flying 90% production plane with all required testing completed for the AWC… even a completed private pilot training and successful check ride in it, so this wasn’t theoretical or BS….the plane outperformed all other c172 models, cost 60% less to fly, eliminated lead gas issue, was quieter and could be installed on different airframes with software changes. So there was no need to ignore us…. It was clear the the thing worked as stated in our paper work and easy enough to stop in and see it if they wanted to….but they did quite the opposite and doubled down and we found our self’s arguing the R&D AWC allowed us to make alterations even though it was a previous certified aircraft… some of us fly for airlines and became worried that they could try to violate us for flying it and parked the thing for almost a year trying to resolve such issues…..but no responses were ever received from our inquires and petitions…. Our plan was to evolve a second c172 to hybrid and that would not happen.

Before flying to osh last year got a call from FAA saying they wanted to come out a talk to us bout a petition we filed over 3 years prior per washing dc office…..they did come out but it was a surprise paper work ramp check for all our program and related docs and they wanted our AWC. We argued the techinical reasons and able to reason with the 2 inspectors and got a new dated document and it in time to fly to osh. Try’s just one example. This visit was likely due to punitive action due to a AIRFACTS journal article I wrote with a project update where I named names .

I’ll sum it up with this which explains the issues we had….. at an air show early on a retired FAA ACO manger told us we will NEVER get anywhere with the FAA…. This surprised me as we had it flying and it worked great…..he said simply the FAA doesn’t have money to support ga piston as it comes from general budget and happy to see it shrink, but the biggest reason is that Cessna and piper sold these planes 50 years ago but get sued every time they crash and have to continue to support the product, and they have considerable influence with FAA policy makers. That sums it up.

I didn’t believe him but he was dead on correct. Just look at the DPE situation and the expense and waiting it takes for a ride, they don’t care young american tax payers wait months and fly hours away to pay thousands of dollars in mostly cash for the privilege. I’d argue it’s by design; look at all the modern and cheap equipment that could save lives like or bags and bigger artificial horizons, FAA did absolutely nothing to work with industry to develope solutions or fast track solutions….. their own study notes simple auto pilots would significantly reduce accidents nd deaths and the reason we don’t have them is primarily due to FAA certification cost! Yet they did NOTHING to develope a solution…. How many accidents and lives could have been saved over the last 20 years if they did… FDA or DOT acts is such cases.

Overall, simply look at the site of ga compared to 50 years ago and it says it all.
We recently sent paperwork to the certification branch to restart the project to see why would happen…..actually spoke with the piston engineer whom never hard of us before and was interested in the project, asked us to Email him formal request and project info to set up initial meeting, which I did, and he responded receipt stating was working on setting a meeting up with managers and me for initial project meeting . That was almost a year ago and still no response even after voice and e mails….essentially the same as last 5 years. I actually contacted the administrator whom responded back asking for names and specifics and stated I would hear something in the near future. But, you guessed it, that was months go and nothing.

We never said we had the solution, but it was damn close enough and a good start that FAA should have at least met with us or return a call or formal emails or petitions especially since all are public servants . We never asked for favoritism, only for them to do their job. They did the opposite at different levels for years and I have no doubt it was systemic from a broken and corrupt culture. The policy and executive level public servants made it clear continuing the project would be senseless. We had the money to design and build the solution, but not enough to buy their influence ….we felt we were dealing with a corrupt banana republic.

I’m not going to argue or debate you on if the project was managed or we were qualified other than to say we were. If any one, regardless of merit of project or their qualifications reaches out to public servants and gets systemically and intentionally dismissed, the system is busted and I concluded over 5 years of this is run by corrupt managers more concerned about continuing to protect big companies than faa mandate to promote aviation. As a development and test pilot and former DER for transport category big planes, I never ever heard of anything llike this, but such programs were all well funded from big companies.

Read the website stufff if you still wamt more info. I have additional stuff but lack the motivation to add it. But don’t suggest we didn’t know what we were doing or didn’t understand the process as some other ignorant member suggested some time ago. The project was shut down and a huge disappointment to many, not to mention an expensive lesson. The takeaway is there’s a reason ga is stuck in the 1950s and unaffordable to most now, and why few try to make a difference.

I hope this answers your question.
 
As listed out by others, even if FAA policy became more friendly to auto conversions, you are not going to hit your target financial numbers of a 100K plane or even a 200K plane.

The only technology that is currently being developed that has potential to make the 200K plane a potential reality would be an electric plane. Fuel source could be battery, fuel cell or some other chemical reaction which requires no parts/manual inspections.... And for this to be viable, both the energy storage cost, and energy density have to increase a factor of three or four at a minimum (using Pipistrel Electro as the baseline). So, it is still going to take one or more breakthroughs in energy storage technology, which means it could be next year or in a few decades. No one knows.

disagree. our concept was to take existing airframes and repower it for total cost of about $30k....a timed out or busted engine c172 was worth about $36-50k at the time, So easily under $100k for a cleaner. quieter and cheaper solution for a full 4 seater. throw in some exp acionics and your Skyhawk would out perform any other and cost about $25 /hr to fly and no lead gas issues. no lsa can come close.

the hydrid design would make the c172 a two seater., which is fine for 90% of missions, but allow use of a smaller engine ....it really wasn't needed as the economics and practicality of the v8 made it most viable solution, but it would be a cool power plant. our ECC software could incorporate it.

new lsa designs may perform better. but won't touch the practicality cost or production numbers a repowering solution would for fundamental market.

I [redacted] knew it. Been saying it for decades, by now. The vindication feels good ngl.

One of my pet projects in .mil retirement will be to start poking into independent journalism on various topics of interest to me. Ones I have not felt at liberty to publicly advocate for or explore on account of my military status. That and well-founded fears of reprisal from employers, which some of my peers doing similar online work have in fact fallen victim to.

Though aviation writing as a stand-alone is not of much interest to me relative to what I really want to pop off about, I'd love to pick at the status quo merchants in public every now and then. I doubt anyone with internal knowledge would be willing to speak on the record about it though. I'm not surprised your "imprudence" at speaking out loud in print would net you funky visits from the regulator. My signature encapsulates the rest of my sentiments on that account.
 
Not sure why you continue to be so interested in our projects points of failure but I’ll end the topic here as its irrelevant to everyone else…
Except its very relevant to everyone else considering you also blame the FAA for all your project’s short-comings. And believing a $44K kit retail price will cover the cost for a Part 33 approval of a fulling dressed GM V8 crate engine and its install on a TC’d aircraft is simply one example that the FAA as no control over.

Regardless, for those who are interested, I’ve posted the links to the current versions of the long-established industry/FAA guidance for certifications which doesn’t require any hobnobbing with FAA leadership or complaining about 1950’s policy issues. The process is well defined with checks & balances on both sides which allows the FAA to issue dozens of STCs, PMAs, TSOs, and the occasional TC to many successful applicants every year with zero drama or issues.

The only technology that is currently being developed that has potential to make the 200K plane a potential reality would be an electric plane. Fuel source could be battery, fuel cell or some other chemical reaction which requires no parts/manual inspections....
Agree. And I think the inclusion of e-aircraft/powered-lift aircraft into MOSAIC points in that direction. However, there are other items at play that I think will keep the cost range in the sub-$200K range and possibly closer to $100K. For example, top tier auto OEMs are bringing their mass-production technologies to the commercial eVTOL industry which will crossover to other future e-aircraft production.

And even on the propulsion side, the move is toward micro turbo-generators turning electric motors and fueled by diesel or SAF. So in the case of an e-SEL or multi-prop aircraft like the Electra, there would be minimal design change and the only batteries on board will be to start the generator and provide limited emergency power vs requiring exotic battery development for added range and weight-savings.
 
Except its very relevant to everyone else considering you also blame the FAA for all your project’s short-comings
you are even more annoying than before regardless of how much I try to answer you…and again it seems you have far more personal, first hand experience and are far more successful in obtaining certifications for new engines on a limited budget to make such a project economically successful. Gee, I never knew FAA had AC’s and other guidance to expedite the process we sought, I wish more entities that have tried to bring innovation to piston ga over the decades was aware of this and realized FAA wants innovation and supports it even from small companies or even individuals when following said guidance ……if so, ga would maybe not be in the decline and have such expense we find ourselves today. If only they could have simply followed such guidance for a smooth and efficient certification process as you point out with these enlightening hidden gems of dark web documents; one can only dare dream of what modern ga would look like ….

It all seems so simple now and surely FAA would have supported our now seemingly ignorant efforts which comprised of mere drawings in crayons and our use of a modified check list and guidance for certifying dental hygienists in Uzbekistan. Who knew? No wonder we experience such set backs. It’s a wonder we even got a AWC or G1 issue paper. Of all the DER projects I worked on and signed off I realize now I had no idea. Thank you.

Please disseminate this to others that want to certify a new critical component, and let them know the FAA will help and usher you thru the process along the way. It now seems so amazing that so many more innovations have not reached market as they have in exp given the 4 step program and eager FAA .

Btw, cert or start up cost is not typically recovered in short time sales, but built into fractionally based on price elasticity models and often use a unit break even model wherein net margins increase once fully capitalized…. This is what higher cost items with big upfront cost normally need excess support function cost funding to reach profitable break even point. so yes , the retail price point may seem low for an aircraft engine because it was as we are conditioned to believe, but it was that for reason as explained and met sustainability level , and we were not looking be make a fortune. But if you have my additional reference materials RE price point strategies for aircraft industry please link as well….. until then I will simply shamefully blame my partner with the MBA and will ask to see his transcript in the morning.

Thank you yet again for pointing our misguided blame to others rather owning it ourselves and delusional self-reproach, and mistakenly following both cert and business norms and our “short comings” which will likely add to our list for discussion at next group therapy on Friday,. Until then we shall absorb and learn from your obvious all-knowing insight, which btw, if it translates to knowing what card is next out of a Vegas black Jack 3 deck shoe as Dustin hoffman’s delightful character in hit movie Rain-man, would love to pay your way to closest Indian casino and supply the chips.

If I may, could you please let me know what you would charge us to start a new STC application and execute the entire cert process? We have all the required testing docs as structural analysis, vibration, noise, EEC software and hardware analysis, prop data, etc…. Please remember to keep it reasonable as the retail price must remain close to reman cost to make it worthwhile for customers to take a chance on it initially and opportunity to grab traction…..so the typical multimillion cert cost will doom it and just be another $100k option.

Otherwise, again, please enlighten others when replying to posts.

If you brought this project to me, I would recommend dropping the 172 STC for now and concentrate on developing the V8 as a standalone item. Make E/AB your primary market which will allow more flexibility, lower development costs, and most important provide a large established market to sell to plus fund your project.

However, all development must follow Part 33/CS-E design requirements to include using your expanding E/AB fleet to build flight data and tweak the V8 design. For examples of this route research the Turbo Tech turbine mentioned in the "Turbine Cub" thread here and at the Hill HX50 helicopter out of the UK. Both are at the E/AB level however are designed to the specific FAA and EASA design regulations which they plan to formally type certify in the future.

Unfortunately, to get an STC retail price point of $44k, it will require a lot of FAA exemptions and ELOS determinations, which if they would provide them, would make your V8 non-ICAO compliant and effectively limit it to the US only with no possibility of export.

Or, if you wanted to expand beyond E/AB look to meeting the ASTM standards for MOSAIC LSA. Or, using similar standards, use the V8 core engine for electrical power generation in the e-aircraft market. Kawasaki, Honda, Hyuandai, and most other top shelf auto OEMs are doing this as we speak.
 
Even if re-powering an old 172 was in the 50k range, I don't think it would move the dial that much. You still have a 50 year old airframe, that was built to be light and not very luxurious. I.e. not much curb appeal. And while a new pilot might be overjoyed at the things he or she can do or visit with their 100k re-engined 172, the bloom soon comes off the rose.

You can buy a number of very serviceable aircraft in the 75-100k range, which brackets what many are paying for a new truck these days. But then you have all the other issues of maintenance, currency, and storage. It seems that in today's environment there are so many other pressing family things that having an airplane and keeping it going just doesn't fit in. And the SEL as a traveling machine is slowly waning as all prices rise, and close-in destination airports either disappear or begin charging more and more. Right now Class B airports often have $40-60 handling charges for SEL; I would not be surprised if that rose to $200 soon enough - there's really nothing stopping them but inertia. Ands the reliever airports sometimes survive and sometimes do not.

There were once rows of SELs at both TEB and HPN. None at the former and every tightening noose at the latter. The piston traveling planes today are Cirrus. They sell all they can make at over 1M each. Cupholders and AC included. So it's a bifurcating market - low and slow, homebuilts, and antiques at one end, high speed and expensive aircraft for traveling at the other.
 
@Steamflyer

Even E/A-B are getting up there in price. Have you looked at the full kit, engine, avionics.... for a four place RV?

Have done so, has gotten very steep. Might as well buy a good Bonanza, but of course there's the pleasure of building your own machine, plus the efficiency of the RV series. Personally I find them nice to fly, but only mediocre to look at on the ground.

there’s do’ers and critics….. you should develop something meaningful… can’t wait to see how it is done.

Has it ever fit in for any but upper incomes?

For perspective, a new base-model Porsche 911 is priced at $150-$200k. A new Cirrus at $1.2M is 6x the 911...is that really any different than a new plane has ever cost?

The best thing that could happen to GA is a continued degradation of commercial airline service levels, coupled with fare increases. The worse Frontier and United become, the better a SR-22 looks in comparison.

And who says I'm not a "do'er" of meaningful projects? I didnt develop my critical knowledge of this topic sitting behind a desk. But if you want to see how its done look into the examples I gave above or to any current STC holder.
 
@AlphaPilotFlyer , I know you've been targeting the C-172 as your application, but how feasible would it be to alter your design to accommodate a popular E/AB type? Say Vans RVs, or similar?

Recreational GA will never substitute for airline service, especially on long routes.

Depends on how long, and what GA plane.

For a trip from south side of Houston to north side of Dallas, my Bonanza is a LOT faster and easier than driving to HOU or IAH and taking a commercial carrier. From Houston to Milwaukee, it’s still marginally faster than a commercial flight with a connection, but it’s a LOOOONG flight without an autopilot. I wouldn’t use a Cherokee or 172 for either, but a Malibu, SR-22, Bonanza, or any twin or SETP is workable for the majority of domestic flights. This is particularly true for people who want flexibility in departure/arrival planning.

My Cherokee is certainly slower than your Bo, but I regularly use it to fly from S. Houston to both N. Dallas and Shreveport. It's better than driving or flying commercial *IF* the weather is good. But if there are thunderstorms or ice, then I'm no-go, so in that sense it's not a replacement for airline service.
 
Depends on how long, and what GA plane.

For a trip from south side of Houston to north side of Dallas, my Bonanza is a LOT faster and easier than driving to HOU or IAH and taking a commercial carrier. From Houston to Milwaukee, it’s still marginally faster than a commercial flight with a connection, but it’s a LOOOONG flight without an autopilot.

EXCEPT when the weather doesn’t cooperate. Your bonanza simply isn’t equipped to handle convective weather, fog, icing, etc.

That’s the difference.
 
@AlphaPilotFlyer , I know you've been targeting the C-172 as your application, but how feasible would it be to alter your design to accommodate a popular E/AB type? Say Vans RVs, or similar?
eddie- actually we designed the engine as a solution not just for C172. The c172 was initial just due to sheer numbers still flying and still being produced. The engine is rated close to 500 HP in marine use but flat rated by software to airframe limit. For example, our c172 can be set 160-220HP, with 220 being the c172 cert limit. it allowed same to be installed on a C182 or Cherokee 6 or C414... but 350 HP was about our limit due to keeping engine stress down for better reliability and longer TBO.

As far as kit AB applications, we looked at it and spoke to some kit builders. The issue was it was more engine than most AB kits at the time could use as most were 2 place, and weight didn't make sense from a weight/thrust perspective as most of the AB couldn't use much over 160-180HP, this may have changed as I see a few 4 place kits now. But to answer your question more directly, the kit could be engineered to fit most 4 seat airframes needing 180-350HP depending on W&B, with mostly software and maybe PSRU gear ratio change. But again, it didn't make sense for most kit designs at the time. We did have a V6 design but after the FAA issues we had just to develop the V8, we were not going to start another project and ended the V8 project soon after. also had plan for a exp crate engine design after developing and selling the STC versions as financial concerns could be absorbed.

But overall, the cost to fully develop and do same part 33 and 23 or CAR 3 or similar cert basis is expensive, even though not required for exp... but we believed it needed some recognized cert basis for our own piece of mind as well as insurance related for owners. Things like designing and developing jigs/tooling for things as engine mounts and wiring harness, structural analysis for engine mount and structures, electrical and fuel system analysis, software and hardware certification to mention a few, are expensive, with many needed to be repeated to a point for each kit. The numbers didn't make financial sense and there was already a company making V8 conversions for exp market that could sell for far less money, and many exp owners wouldn't likely see the value in the cert. Contrast that with a C172 or PA28 that are almost identical and unchanged over several decades, allowing one kit to meet thousands, even tens of thousands, models and that are still in production.

We did speak with a kit builder working on a 6 seater design about adapting design for our V8, but don't think he got very far.... but a high performance 6 seater cruising at low FL's would be ideal candidate.

Convective and ice, agreed. Fog is only an issue below minima (I normally file IFR regardless of conditions).

My solution is to always have a refundable ticket booked with Delta and roll it forward to the next trip when I fly myself. I fly enough long international legs to have diamond-tier status, so they let me do this without fees or penalties (so far).
