RE: SUPER REAPER MAIDEN FLIGHT SOON NEED ADVISES
At high AoA you can get tip stalling which translates into a large displacement rolling motion back and forth. I've heard of a couple of other Reapers doing this.. I am going to do some mods to the wing tips to try and get rid of this...
We (my buddy and I) had full flying canards up near the pointy end. I found adding elevons as well made it way too pitch sensitive. The Canards were limited to 13 degrees up and down. Rudder brakes work well, and there is no pitch change when they are deployed. The photo below shows it just after touchdown with full up elevator (canard) and full rudder braking... you'll also notice that the elevon mix is turned on because my son was flying it......
