At one point he put it up for sale. I do not know what became of that, if it sold or not. He is the former owner of the now defunct Blue Mountain Avionics out of Tennessee. I met him once when I flew in to have an EFIS serviced.
Yep, was up for sale a couple years ago. Saw it at RHP around 2005. Like Blue Mountain Avionics, the Cozy jet never caught on.
...but can you please make mine a Velocity XL Extra Wide?
Also... faster. 200 knots is nothing to sneeze at, but the Velocity XL supposedly already does that...? I'd like my turbine to boogie baby. Can we go 250 or even 300 kias in one of those things without ripping its wings off?
...350...? 400 knots?!
Granted, I couldn't afford the gas for the engine that could produce that speed, let alone the aircraft. It would be fun though!
Yes, I think you'd be looking at ripping the wings off a canard EAB at those speeds. Even a Starship has a 245 KIAS Vne.
Fine. Turboprop RV-10 then.
Yeah, that qualifies as cool.
At least one Velocity jet flying as well.
Saw this at Oshkosh last year:
Saw this at the Reno Air Races last Sept. Now owned by a gent named Ryszard Zadow who is using it to promote a project of his called the "Rutan Aircraft Flying Museum".
Just happened to be walking by one of the hangar rows and did a double take when I noticed the back of the plane looked "different". Had to walk over to have a closer look and chat with the owner.
Is this the new engine for your Vareze?
geez, I had no idea!!!
very cool, but again I was hoping for "wow" cruise speed... I think he mentioned they got 170 kts that day... with a $110,000 turboprop! doesn't an old bo with a piston engine go that fast?
I know nothing, so just unrealistic expectations...
No I'm building a 0-200 for it. got most of the parts gathered except the light speed piston set. 1200 for 4 pistons, rings, and wrist pin set.
I met Greg Richter when Blue Mountain was still a going concern in nearby Copperhill, TN. Actually flew him somewhere in my Cirrus to check on some work on that very plane.
He's a character. I'll see if I can dig up a photo.
I recall he wanted me to instruct him in that plane for his instrument rating.
I had a good look at it at the display at Osh and spoke with one of the developers. The installation is very nicely done. Other than the cowling I suspect the rest of the airplane is probably a stock RV-10 airframe with no structural or other modifications for higher loads or speeds, as they seem to be concentrating on proving out the engine package.
Extremely cool. And gosh, that Len Fox. Although, he test-flown a LongEZ with a rocket engine (not just jet, rocket), so this sounds rather natural. Nowadays he's doing mundane things like flying Mooney M10 for the first time. I suppose his wife needs new shoes... (Roger is the only guy in this room to get this Babylon 5 reference).
I think I heard John Monett (unless it was the late Jeremy, actually) mention that they hoped to get by with straight gear on the Sonex jet too. You know, SR22T goes above 200 knots like that. However, with T100 power there was no way. They had to institute folding gear eventually, or else the speeds were too un-jet-like.
I'm thinking that a lot of folks have spent a lot of money on experiments that go slow. I'm certain a jet powered Longeze will exceed 170 knots. the Varieze I bought was clocked at Reno at over 200 with a simple 0-200 with high compression pistons, and stock mag ignition.
Here is My Varieze at Reno with Tom Watkins at the controls.
SubSonex kit has a cruise speed of 208 knots and Vne of 250 knots. This is BTW the cruise speed of some old King Airs. One needs a seriously clean airplane to go to 300 knots. Smaller cross-section, tail just right to be thin yet not too long to increase the wet area too much. Greater wing loading to decrease wet area again, meaning massive flaps. No matter how you slice it, you need an all-new airframe with these characteristics. And possibly over the fence at 130 knots.
...and isn't that the deal killer right there? If not for that little bump, the Lancair IV would perhaps be more coveted.
I'm thinking big money will go to the guy who can design something that will cruise like a Lancair IV, yet still stall at 55 knots flaps extended.
I think this is a case of having your cake and eating it too.
The 55 knots figure may be tough. Cirrus SF50 cruises at 300 knots and stalls at 67 knots. That's probably close to the limit that can reasonably be achieved without a serious NASA-style flexible wing.
The ever-popular L-39 cruises a shade above 400 knots and stalls at 100 knots.
That is pretty close to the Lancair Evolution with a 61 knot stall speed.
I had to google those aircraft. All were very cool!
I want an aircraft with the L-39 speed, stall speed of the Evolution, easily seats 4 big people with full fuel, sips gas like a 172, and costs the same as a new SUV, please. To go.
sorry I'm drifting this thread...
I guess we can want ?
yah, it's definitely having my cake and eating it too!
Get drafting!! When you have a mock up let us all know.
I kinda already did... I started with this:
...and decided the best design was going to be a mixture between the fastest aircraft, the SR-71 Blackbird:
...and the fastest shark, the shortfin mako shark:
So I started twisting, and stretching, and moving, and soon figured out that I was in way over my head. I wanted to eventually test it in something like this:
You know, that would make a cool POA contest!
Who can make the fastest 180hp aircraft using that Open Vehicle Sketch Pad? It must have fixed gear, and be able to fit four people (sitting up, fairly normally, with at least some kind of comfort).
It should stall at 60 knots or less.
...and someone who actually can design something useful with that tool should judge. Do we just go top speed?
cool looks complicated
Sadly, Van's even opposed the use of turbocharged engines due to flutter concerns. Quite a shame, as this would turn the RV-10 into a potent SR-22 competitor and an even more capable traveling machine.
Not anymore. IIRC, there have been two Velocity's with turbines. One crashed and the other had the jet engine removed and a piston engine installed. The range with a jet engine is just not practical.
My hangar neighbor bought it and flew it for several years, Frank Dasmacci. He ultimately donated it to the Rutan museum about a year ago. I always knew when he was over my house. It was an unmistakeable sound.
