RE: Reaper: magnitude for control surface throws?
Propellers,
Yes, I flew a few dozen flights without any elevon (pure canard elevators only). I found not too much difference with elevons mixed in at high speed, but a lot easier to get the flare for touchdown and also the take off rotation seems easier.
I am uising a KJ66 based engine producing 20 pounds thrust. The plane flies much faster, and takes offs especially are awesome. Allthough, once airborne, cruising around at 1/3 throttle is all you need for confortable flying.
I also have my rudders/fins glued onto the fuse and have not experienced any flutter. I am using Hitec digital servos with metal gears on my rudders (and ailerons and elevators as well).
