I set mine up with flaperons, two positions. I can slow the plane down to a walk and the plane is still maneuverable. The high stab works more efficiently than I first thought it might. See my earlier post re cutting an access panel to get access to the back of the firewall. It hasn't weakened the structure in the slightest. You will note that the thick firewall is not tapered to match the rake of the fuse so I filled the gap with epoxy-micro balloons to strengthen the firewall. I also drilled a new hole in the main gear to move the wheels up another 1/2 inch.
Enjoy!
