I have a friend that I helped get his flight trimmed and flap to elevator mixing setup. Set your control throws to low rates to start out. The control are like way huge! You can always increase to your confort level little at a time.
The flaps work great and you can fly steep approch to landing. I have 20% down elevator mixing with flap deployment on my friends Wild Stick. The airplane is a little tricky on takeoff, maybe because of the tall gear? It may help to use expo on the rudder.
Good luck, Believe you are going to have a blast with this plane.
