GP Big Stik 60 is what I am flying a lot right now.I do have the Evo 100 NX hanging on the front.Set up with trike gear it don't have a lot of prop clearance. 14x6 as recommended in the manual bites the ground on the grass runway a little.It don't take much runway on take off.Straight up and unlimited!However the sound got me in trouble at the club with noise complaints.I switched to a pitts muff and that didn't help with the noise but gave more hp. I switched to 14x8 prop and I think it might pass the 96 db test now.Lost some pulling power but gained some top end at lower rpm's.
