Not seeing any bipes out there to my liking, so making my own. My friend Blake wants total precision and something that lasts. Used to use CA hinges and sealed over gap with tape. Now I know better. Using Micro Dubro pin hinges from now on. Leaves such a small/too no gap, no reason to tape over. Much more durable hinge system. The surfaces will flop around now and droop without being hooked up to servos. Much easier on the servos too. Of course if your plane already has a single sided bevel on ailerons...I did wing side flat and double beveled aileron side. Once done that's where it will stay. All my planes from now on will have them. My 2 cents
