I use a YS 63 in my Funtana with an APC 13-6 prop running 10,300 on the ground. I wish APC made a 13-5, that would probably be perfect, although I do have a APC 14-4W to try yet.
It will KE loop with standard futaba servo arm and 3004 servo, I am running 3004's all around.
I also experince the right wing dropping doing a wall, mabe I need to add some weight to the left wing.
Tucks to the belly on KE, but can correct for it.
Flats spins ok, but not super flat yet. It hovers pretty good, I am learning on this plane............
I did make the brass tubing mod on the wing dowels and put that problem to bed.I think this is a great airplane, the more I fly it the better I like it and the more fun I am having............
