RE: Showtime 4D 2C Engine installation
Hello all,
I would like some help regarding the ShowTime 4D 90. We went with an OS FS-120 w/pump and balanced it at 7.5 inches from the leading edge (about where the triangle shape hole in the fuse is). I have test flown this bird now 3 times and been lucky to get it back on the ground. It is super sensitive to pitch and tip stalls very easily. In a 80-90 degree bank, I will apply normal back pressure and the result is a stall and opposite bank. When I attempt to land, a slight amount too much elevator and it will balloon terribly. I tried the cg forward (4 inches from LE) and the tip stalls worsened. Also to my surprise, even the OS 120 seemed a bit under powered, don't think it will hover, although have not tried (still just trying to fly it).
What I could use some help with is the correct throws and expo settings. I really want to think this is a setup problem. Apologies if wrong forum for this question, first post.
