I fly a couple Wild Hare birds with MVVS 43cc engines, the Extra (16.25 lbs) on a wrap around pitts, and one on an 16 3/4 lb 84" Yak (Prototype that turned into the Sukhoi) with a Canister setup, and have had NO Problems!
The canister setup is worth every penny!!!!!!! Turning a NX 22 prop @ 7400 (warm). I am sure the 58 would be MORE than enough, especially if you put a canister on it! Would be awesome power!!!
