If you have an hour to kill this docu-comedy is worth a watch. It's not terribly flattering of the old time CAF, but it is really funny. I think you will find that the "Defender" has a lot in common with the Raptor...

Along with video of a small wind foil mounted on a clapped out pickup truck and attended by an observer with a crash helmet monitoring Flintstone era testing equipment, you get this narration gem:
"After testing the Defender wind foils in the wind tunnel, they are mounted on a high speed platform and taken on a journey to the very limits of the aerodynamic envelope".

That the narrator can recite this without laughing is laudable.

Along the same lines, I heard this on a podcast yesterday and there were many parallels with the comments about Peter in this thread. Luckily the escrow refunds are already planned, otherwise the parallels might be more concerning.

Something that may be of interest to Peter and others:

Cool video. Cool airplane. The differences in the flying characteristics are interesting. It looks like fun.

Paul needs to learn how to wear a seat belt though. If he needed it it'd probably kill him the way he's wearing it.

In that AVweb video, “Pitch Buck” is mentioned and can be seen in that video as vertical pitch excursions due to canard incidence, which makes the canard design essentially stall proof since the canard stalls before the main wing. Is this what we are seeing in Peter’s first flight video (pitch excursions)?

An actual audi diesel development engineer responded in his latest video and told him to remove the second turbo. Told him he would gain power and egt's would drop. Totally dismissed him because it wasn't an easy fix.

Never enough time to do it right.
Always enough time to do it again.

Mike,
Why would Peter listen to anyone? Hold my beer, Peter’s got this!

I'll give the guy credit too, he's persistent...he put that same message on the last few videos, starting with the first "flight" one.

It's interesting that removing a turbo and redoing some pipework and oil fittings is too much work, but he instead had a bespoke random coolant tank fabricated and plumbed into the nose baggage just to buy more time from the overheating...

The real issue isn’t that it’s too much work. Peter’s invested in what he’s already built as being a revolution in GA and superior to what other have done or can do. To go back and change a major design feature like the staged turbos would be to admit to himself that he does not know more than all other GA people, and that may be he knows even less, because few projects with his resources get to this point in development with so many fundamental problems still to be solved.

He’s doing things that don’t seem to actually get him any closer to fixing anything. Don’t get the coolant tank at all, maybe he should just put ice packs on the engine. What does any of that have to do with solving the cooling problem? Same thing with the gear, seems like a project some students would have to “see what happens” but without a specific plan in mind. I must be missing something.

I’m curious how this is going to end. Slowly and quietly I fear.

Raptor flew, engine overheated.
Defender didn’t fly, engine didn’t overheat.
Sorry Doug, no similarities.

Great video, Doug. Thanks for posting.

That seems better than suddenly and fiery, and those appear to be the most likely possibilities.
