RE: Lets see your ULTRA SPORTS !!!!!!!!!!!
I wasn't impressed with the SuperTiger .75 (Italian version) in my US 60. It was fine for general sport flying and was pretty quick on a 13x6, but just didn't have the oomph for IMAC/pattern practice. Had to fly in a small box for shorter uplines. Sometimes I think the small overpowered .40 sized planes I've built have ruined me for life! lol
BTW, my favorite manouver with my US60 is 80mph touch n' go's. They're a blast!!! Just don't try it with a tail dragger version...
