(because the other thread is long and quite difficult to follow, a new one)

I've did already 15 flights with my showtime 4d. I'm not very happy with it. It's equiped with a saito 120S.
When I pull up quite roughly in flight on half throttle the showtime snaps out.
I've moved the CG to the back. It snapped less (I think). I don't know if I can put the CG more to the back because last time during the landing the showtime felt backwards which resulted that my tailwheel touched the ground first and the plane felt hard to the ground and my mainwheel carbon broke and smashed in one main wing.
My Showtime is underpowered. I can hover it on full throttle with a 16x4W prop (not for long). Maybe the underpowering could be the reason why it snaps so easily...

Does anyone have a showtime with the same engine as me, but who can hover properly (not on full throttle). If so which fuelmix and prop are you using?

Some thoughts I had: - Maybe the Showtime isn't made for (extreme) 3D flying.
- Because it's underpowered, you always have to maintain speed??

Does anyone had the same 'snapping-problem'. How did you solve it?? How is your CG?

Thanks!!
