    So, wait a sec... is he really blaming the guy who invented the first tab washer? Or, whoever designed the generic Home Depot tab washer he installed on his aircraft? Because last I checked, it was the responsibility of the engineer of the design _utilizing_ said "generic part" to ensure it...

    So basically he's talking about a small gasoline or diesel engine driving an electric generator, a small battery pack, and a pair of self-contained electric ducted fans? And he thinks that will be lighter than an Audi diesel engine plus a redrive and a propeller, and will have a ton more...

    Not sure where you got either of those impressions. Raptor is not at Oshkosh but iirc Peter planned to go. And afaik Peter still believes Raptor is going to be acquired/completed by a mysterious west coast company.

    The airplane Elliot was testing in that video was not a freshly-built one-off prototype, it was a proven airframe of which ~60+ are flying in the US that was completed years ago and accumulated ~140 flying hours. The reason they asked for a test pilot was that they had experienced gearbox...

    If that were accurate, I'd be lining up to buy a Raptor! According to that graph he left the runway at 24kts nearly vertical and almost instantly reached 300+ft _WHILE_ accelerating up to ~85kts in a matter of seconds!

    10/23 Raptor Video

    I think what he means is to put the engine on a different type of aircraft, either a kit/experimental or even something certified, and use that JUST to test and develop the engine. Then take a certified engine and put it on Raptor, and use that to JUST test and develop the airframe. This is...

    I don't think that FAA registration information is technically a determiner of ownership... For example, I might purchase an aircraft from someone, via a bill of sale that has been executed, and take possession of my property without having to wait for the registration information with the FAA...

    Just for academic purposes, does anyone have a list of the days when his flight ended with an urgent request to return and land? First flight, the day the engine blew up, this low oil pressure light... any others I'm missing? I'm not just thinking of the days he formally declared an emergency...

    Actually the third longest flight of this aircraft this year. Longest was 51 minutes, next 28, then two 24s, 23, etc etc. According to FR24, total flight time on the airframe is currently 10 hours 40 minutes over 25 flights, for an average of 25 minutes per flight.

    Transcript from LiveATC: PM: Valdosta Tower, Raptor 2TD, uh, I'd like to descend to the field. Tower: ... make right base for runway 35. PM: Uhhh, can I make left traffic for runway 17? Ummm, I'm not declaring an emergency yet, but it's possible I may declare an emergency here in the next 30...

    Geebus, just listened to it. He's asking for opposite pattern/runway direction to what tower wants, and says "I think I'll be able to make that," but refusing to declare it an emergency. I hope tower just went ahead and declared for him (they can do it just by putting the EM on the radar...

    Wow. First off, hard landing! Glad the pilot was ok. I do not see a full parachute in that image, just something that looks like a drogue? It's possible the full chute was removed by rescue crews before the photos were taken, but it's also possible that it failed in some way and that failure...

    I'm not vibration expert... but I have mounted a lot of GoPros on a lot of WWII warbirds. Those aircraft often shake like _crazy_ compared to new stuff, especially aircraft with big radials. Our B-25.... well let's just say it's pretty challenging to get clear video if there are any parts of...

    Oh my lordy.... smh Raptor Aircraft 2 hours ago The wing isn't vibrating. The gimbal in the camera is being affected directly by the prop wake.

    The lowest speed at which the aircraft can maintain altitude? That seems to be the ultimate practical limit. In other words... how fast will you be going when you hit the wooden house with the family of 4 in it?

    He is the designer of the aircraft and powertrain, it's his responsibility to understand the design requirements of a part, and to ensure the finished part meets those design requirements. Nobody "expects" him to have heard of Delrin, but REGARDLESS of whether he'd "heard" of it or not, his...

    Sounds like a huge increase in the volume of coolant required, which in itself is going to add a lot of weight. Airliners use an oil/fuel heat exchanger in the fuel tanks to keep the Jet-A from slushing up too badly at the very very cold temperatures they operate at, but those are able to be...

    Jeezus.... HE IS THE ONE who told everyone what his "plans" are via an ongoing YouTube series. Now he's bitching that we don't know the plans have changed, when he hasn't mentioned the new plans in any video? We're supposed to be mind-readers now? Just childishness.

    Observation the first: That "machine shop" should be ashamed of themselves, there are still burrs and bits of plastic sticking out on several places on that part. Deburring delrin is the easiest thing in the world, it takes 2 seconds and no effort, but clearly they just didn't give a ****. But...

    I live in Boeing's backyard and about half of my friends (and myself) have worked or do work there. Their problem isn't technical, it's cultural. It's too off-topic to get into here, but the way I'll tie it in is.... PM would fit in _perfectly_ there.
