I have an OS Wankel on this plane and I haven't had any problems with the plane snapping on takeoff. I did break one stab when it flipped over on a landing (the wheels caught a clump of thick grass). My plane takes off at 1/2 throttle nice and scale like. Also, mine doesn't bleed as much speed as I would have expected. Maybe my CG is more forward than the others. If I remember correctly I balanced it per the instructions. This is a great little plane, it handles like a much larger model. The only issue is you will need smaller than standard servos.
