the hardware that comes with the kit is just for one aileron servo. Just one servo on the aileron works fine on the tensor. I had 2 stock tensor, they work well, just a fragile airplane. The stock location is good to, just be carefull cutting out for it. They will still fly good though when they get heavy like mine is. I have lots of balsa and expoxy on mine. Im combating it this weekend in foamy combat at the funfly so we wil see if it makes it through it, but i have lots of other foamy kits.
I made an EPP 6mm tensor already. I used two servos for the ailerons on that plane. One for the top and one for the bottom wing, and just used a y harness. That worked good too.
