Wing Fences
Geoff I did a similar mod to my GSP Staudarcher and I noticed a definte improvement.It still needs triming and I'm working on thrust offset etc.I'm considering installing the tip plates to further improve it.I cut the ailerons 6" in from the tips and raised them 1/8".I felt a lot more confident flying it last night on my 6th flight doing some tighter loops.Thanks for the tip...Steve
