This is just a little vid of my Depron profile SU-37 Rev5 in a nearby park, it's not a conventional depron jet, it's kind of an odd 3D hybrid (it has the control surfaces extended into the prop wash for post stall maneuvering).

Awesome flight, Kai! Have you thought about making one with a LE turned down to increase stability at high AOA? I notice you get classic wing rock when the planes attitude gets up at slow speeds.

I think JetSet mentioned one time that toggling spoilerons on will help keep airflow over the wing surface when at these high AOAs. This could help too if you have a computer radio.

Very cool stuff, 3mm depron?

Thanks ToxicToast,

The problem with having LE droop is that it wouldn't be able to harrier inverted (I have a symetrical slat design that I just didn't get around to making on this version). This plane already has "spoilerons" in a way, the ailerons and elevons are tied together (elevons go up, and the ailerons go up at a reduced mix ratio).

This one is actually made of 6mm depron, spans 25" and with a TP1320 3s is 9oz AUW (I fly it both outdoors and indoors).

Here's a vid of the control surfaces I made a while back:

P.S. Not that it makes much difference to a plane like this, but I've switched to a DX7/AR6100 recently, so the flight vid is on the new radio.
