I was thinking about a Aeroworks Extra 260 75cc. Would the Evolution 58GX2 be enough? I do not know but think it would be interesting effort to attempt. Here is what I was thinking.

Aeroworks 75cc Extra 260
Evolution 58GX2
8711's with Titanium links, standard on throttle
AR 9100 Rec.
A123's Fromeco Extreme, 2-rec 1-ign.
All Carbon tubes, main gear & tailwheel
Will it work I dont know, what plane are you flying with the 58, and AUW?.
