    Why can't watching in amazement and disbelief be a hobby?

    I wouldn't go that far. May very well have just shut down after landing to minimize the engine damage. Or knowing his ways, he might have even shut down in the air to limit damage.

    Whatever the cause I bet his butthole was puckered up pretty good. Glad he’s ok.

    Or an engine that pulls water from the atmosphere and then extracts hydrogen and oxygen to power an engine. Think of all the additional weight we could carry!

    Now if those luddite engine manufactures would just stop playing around with these 100 year-old engine designs and make this happen.

    Ah skip all that and go directly to an Infinite Improbability Drive.

    The Raptors pressurization will come in handy for that!

    Everyone knows you can’t go directly to the infinite improbability drive. First, you need to build a finite improbability generator and calculate the precise improbability of the infinite improbability drive existing.

    He'd manage to overheat it while running in the near-absolute zero of space lol.

    There's nothing to dissipate heat to in space. It's very very difficult to cool things and you essentially only have radiation cooling at your disposal. There is no convection or conduction for other molecules to take the heat away... since there are none. If you put your phone in a vacuum it would overheat VERY quickly.

    Beat me to it.

    The upshot is that there isn't anything IN space...so it doesn't have a temperature. So it all depends on radiating heat away, and a car-type radiator wouldn't do very well. It depends on air passing through the coils and absorbing the heat.

    The Space Shuttle's radiators were on the inside of the payload doors. If they launched and couldn't get the doors open, they'd have to land real quick before the vehicle got too hot.

    Way to overthink it, lol. Yes, we're all aware that there aren't many molecules with which to pass the heat off, but radiating the heat across a large surface area or using it for cabin heat would be appropriate. My point was that Mr Raptor would fail to address those points before he ever got to space with his improbability drive.

    Were my eyes playing tricks on me, or did that thermostat housing/Oil filter mount on the Audi motor look like plastic? God know the vibrations/harmonics a redrive and prop are putting into that motor, and to trust your oil pressure to a plastic assembly?

    Looked like plastic to me. You might be right, but they're doing impressive things with plastics these days. It could be more reliable than an aluminum housing.

    Maybe his future is in film, not aviation. Generally, you don’t end up with serious mortality risks in the film industry.

    Yikes the oil hemorrhaging from the cowling.. wonder if there’s a hole in the block.

    The way he's talking it doesn't sound like he thinks the motor is destroyed as he's talking about other band aids to come. Gotta get the Garmin riff in there too in how he doesn't understand why the autopilot kicks off when you manually put an input in.

    I would suspect one of his rube goldberg piping solutions either came loose or cracked a cooler.

    I thought the "to be continued" thing was sort of dumb but having just lived through an engine failure in your own plane/own design I can sort of understand the enthusiasm in adding theatrics

    ..he mentioned the redrive a couple times, I wonder if he suspects that's where the oil came from?

    My big question is.. is the engine hosed? Presumably, 'yes'?

    Does he try with another audi or bite the bullet and toss an established GA engine in there?

    With that much oil, I would think it would be easy to see where it came from upon opening the cowling. Seems like it was coming from further forward, but of course pressure can throw fluids around. I think maybe his comments about the redrive are a red herring, part of the drama...he wants the "haters" to assume it was his goofy redrive so the big reveal can be something else and he can gloat that the redrive is fine.

    Either way, it's probably more likely than not that the cause was something he did in a non-standard way, rather than a freak occurrence. Things like this happen, but when it happens to Raptor, it's tough not to jump to the conclusion that he was somehow responsible.

    Assuming the engine is junk (I have no sense on that one way or the other) there's another question...does he know it? It could be damaged and still run. He might think "if it runs, it's fine." He sure sounds like he thinks this is a minor hiccup and he'll be flying again soon.

    Not necessarily. With the air moving around that engine compartment, even a 1/4 cup of oil could cover almost every surface in that engine compartment making finding the source rather difficult.

    But here's what I predict:

    He'll have figured out the cause. Fix it. Have no idea why it happened. But he's okay with that. And then promptly take off again.

    1500 fpm descent and 100 knots with a windmilling prop? That's a lot of drag.

    1. He hit the wing on the ground on landing, really for no good reason, and it didn't seem to be that radical a landing. This thing is not stable.
    2. He ran the engine dry of oil and seems to be planning on slapping in a new seal and flying with it.
    3. He ran it in the first place with nothing holding the seal in *you can't make this crap up

    Again, I'm amazed it ran that long, and I'm amazed he's still alive. I fear he will not live long. He's quickly using up his nine lives.

    How can you know when you don't bother to test any of that boring stuff?

    My back of the napkin calculation based off the foreflight data is that it was, at best, 8:1.

    Hell, for all we know he might have been doing 200 knots. I forgot his IAS isn't much more than a random number.

    Given his explanation for why the engine shut down (the turbos got so hot they coked the oil and stopped turning), what are the odds that the turbos are damaged?

    he said they're fine.. to quote him directly:
    "the turbos look fine, as you see I've basically spun those, they seem fine" 11:50

    ..another gem:

    "I might just trim it off [this part of the wing off that I hit] and make the other side match"

    holy hell, we are reaching new heights of idiocy in this last video

    I always need a good dose of competent DarkAero YouTube videos after insulting my intellect with one of Peter's abominations

    I especially like that the seal needed to be replaced after about 100 hrs of engine runs because it was starting to wear down, nevermind that he decided "nahh that's not going anywhere" (another quote) only to have it, shocker, go somewhere and invoke his guardian angel

    I have almost zero experience with carbon fiber so I’ll ask...

    The carbon fiber fabric under the bit that wore off seemed very flexible. Is that normal? I have some very thin carbon fiber parts on my Sky Arrow and they are quite rigid.

    Depends on the resin used and material thickness. I’ve made some parts that were quite flexible and I’ve also made some parts that are nice and stiff.

    Yeah, I heard what he said. I was hoping somebody who actually knows says something.

    Enough acetone and it'll be fine. (I wonder what the oil seals in the turbos are made of? Something acetone might dissolve or weaken? Maybe?)
