Apparently just imagining the need for such a system is beyond his ability.

Even if all of the stars aligned and he got this thing to a state where it was flyable and didn't weigh in like an African elephant, there are so many of these design issues that making a marketable kit out of it would still require a huge redesign.

He's way past thinking of that. He seems to be a 50/50 mix of easily distracted and tunnel visioned. In any case, he appears to be completely "winging" the pre-flight testing. Is there a test program he is planning, running, and recording for each run?

2500 ft ground roll to 100 knots “indicated” and it’s glued to the runway.

One person, no bags and light on fuel.

2500 ft! Holy cow!

Yeah, not to say that's not a bad thing, but the "glued to the ground" is more a function of the weak trim spring allowing the elevator to float up instead of lifting the nose. I have no idea what liftoff speed will actually be, but it may well be right at the calculated value provided that the elevator is actually used to raise the nose.

Given that the readout for the calibration was a voltage from 0-5V, it does seem like a resistance pot, and not a digital encoder. My speculation, based on the failure mode illustrated in the chart, is that the pot rotated relative to the lever, perhaps it is not tightened down or otherwise prevented from moving. I would have expected a loose wire to have sent it to zero or full scale.

He is not using an Audi ECU. He is using a MOTEC

every modern diesel car and every truck you pass on the highway, has a "throttle" by wire. This isn't unusual or difficult, in fact for a an electronic diesel it's the only way it can work.

It's only hard if you start trying to change what works. If you're using an engine from an audi car, bring the controls from the car.A guy in a shed is not going to improve on VW's engineering. Even if using an aftermarket ECM it's still going to be set up for the car control inputs.

I guess he is not the only one with those ideas...
Successful flights with their prototype. Already have 35 hours.
Laminar flow. Diesel Engine. Long Range. Pressurized.

New video up. He plans to fly. Wearing a flight suit now and told ATC he was going to do a high speed taxi “but might take it flying into ground effect.”

I heard that his flight suit will make him a better pilot. I don’t think we know anything about his flying qualifications. I would certainly be getting a lot of recent experience in a Velocity and a Lancair if I was him.

He’s a CFI. That means he can fly anything, but it has to be from the right seat.

Throttle belongs in the left hand, stick in the right; just not Peter’s.

First I've ever heard of this. This thing looks like a flying submarine. The claimed numbers are impressive. I hope the wing spar is some kind of carbon nanotube structure, because the wing looks puny.
