The latest vid covers a lot on the lower gear door actuation. Sorry to say, but all Peter's ideas look bad here. I don't think any of the present plans will work with the air loads present in flight. Anything he's designed on the plane with regards to linkages and latches seems not to work even after several iterations, despite modeling in CAD. He could learn a lot by looking at existing designs instead of trying to re-design the wheel so to speak from scratch. The elevator geometry still looks "awkward" here: His verbal discussion about the redrive re-design to get oil to the prop sounds complicated. Again, he could save a lot of time by looking at existing PSRU designs which run oil to the prop shaft.
