I did a search on the Sig Cap. I found a few people who said the O.S. 1.60FX was a little to much engine for this airplane. I am new to aerobatic flying and eventually would like to try some 3D stuff once I get good enough. Would a Moki 1.35 be enough or maybe a YS 1.20FZ? I just don't want a plane that is ridiculously overpowered. I really just want to do all the basic aerobatics and maybe get into a little 3D.

Thanks,
Tony
