They've also stayed dark for quite a while, pending a few court cases. Think less Canadian, more Australian inefficiency and grift. "We will build you something we need." "What's this 'We' poo poo?" "We will build you something we need." "Oh.  "

That might explain why the only surviving T-47A/552 had it's cockpit ripped out before it was delivered to the community college that uses it now, I guess.

Any drunken lurching or wallowing you may have seen in the video is a result of bumps in the air, definitely nothing to do with potential design defects in this mans diesel fueled fiberglass monument to messrs.

The youtube comment circlejerk has returned in full force. Either that or he's deleting critical comments again. The turn to final and landing sequence starting from about the 6:45 mark has some terrifying oscillations. They're masked a little by gopro image stabilization until you realize that the horizon out the windscreen might not be moving much, but the airframe is lurching around like it's blackout drunk. It's not just pitch instability, looks like there's lots of roll instability too. Maybe all three axes. One of the themes that came up over and over in the homebuiltairplanes forum thread and those Wasabi videos is that Peter designed and built much of the control system himself, and he's bad at it. Doesn't know poo poo about mechanical engineering, comes up with rube goldberg systems, and implements them poorly. So there's tons of compliance and springiness everywhere, and plenty of ways for it to fail because parts of it are horribly underbuilt. I have to wonder how much of that's still going on. Wasabi pushed him to improve the control linkages a lot, but weren't able to finish the job before he fired them. There's a chance his control surfaces are still free to wander around and do what they want, or introduce a spring-fed oscillation into the system.

there's a part in the wasabi video where they are looking at the jackscrews for the landing gear and they're like "...are these bent?" peter replies "yeah, they came that way, that's just how they are. they can't make them straight because they're too long" as if humans are incapable of making a two-foot-long metal screw visibly straight to the naked eye. as if we could have progressed past the industrial age without that sort of technology. that kind of stupidity, that particular head-in-the-sand ignorance and unwillingness to examine his assumptions, is what i notice about him again and again.

BobHoward posted:The youtube comment circlejerk has returned in full force. Either that or he's deleting critical comments again. In the previous video with the high speed taxi, he makes a remark about the elevator not being pushed up into trail by the aerodynamic forces. I commented on it asking for clarification and was told that it was expected because it’s a spring trim system, therefore that behavior is normal. I was thinking more along the lost motion and compliance train of thought, given all the other issues seen, but apparently it’s okay

 Is it a) World's best panel gaps for retractable gear, or b) Explosively separates landing gear at takeoff and touches belly down on grass, or c) A non-flying article designed to soak up government contract money with no intention of actually flying a space payload in the next 12 mos
