the elevons are hinged with glass tape from the bottom and the top, and then gone over with the coloured tape, these babys ain't going anywhere, they taper with the root being thicker, for me this keeps the elevator where its meant to be and i'd be happier with a forward sweep on the TE, the correx can bend when you start going over 80mph which makes the pull out a little fun
i do have allot less rate than most of the other Vipers, and allot less response and turning ability, turn it up and it'll turn as its meant to, but induce the stall death spin if provoked too much.
it is optical, one elevon is down.
its behavior can be best described as walking... the wing tips don't want to remain behind the plane and neither knows which is meant to be in front. just looking through my vids, but i cant find one that shows it well, after stall turns the wing on the outside trys to over take after your already heading down. stalls also are flat and it walks down and back rather than dropping the nose to let you get flying again
would more rudder area help? my flutes are open on the fins and run horizontally, can this be a reason?
