It is just structural engineering. Put the right
amount of material in the right place.You can see
the pivot shaft in the videos.
I suspect the entire turtledeck fairing is non structural.
That motor design is in all sizes from very small
to many 10s of kilowatts. It is called an
outrunner. More torque at lower rpm so you don't
need a gearbox. The electromagnet coils are fixed
and the case has the permanent magnets inside it
and rotates with prop attached. No brushes as
they are 3 phase AC. The 3 phase is generated by
solid state electronics and the current is pulse
width modulated for power control.
So an electric self launch, light weight, 50:1
15m glider capable of flying at 60 Kg/sq m with
built in ballistic chute. If they go as good as
they look I think Peszke's main problem will be ramping production.

Very nice. Rapid extension and retract. I
have seen that motor somewhere before.
I did like the large access panel to the motor
compartment. Not sure how they maintain adequate strength in that area.

Any à good links?
I found a schematic diagram which indicates
that the motor has a pusher folding
prop.ÃÂ Not sure how it retracts and fits in
the fuselage with the blades sticking up?
Here you go:

Scroll down to the videos. They took quite a
while to load here. The link seems slow.
Sheer bloody genius I think.
