I was looking at getting this,however, the engine seems a little small for the size. I already have a QQ Yak 54 for 3D. I wanted something to replace my Four Star 60 for a little more capability for IMAC/Fun Fly. Anyone with experience with this airplane please advise on engine size.
Also, what would be a fair price for a professionally build Four Star 60 kit plane?
It has a ST 90 on it with 2 gallons run through it.
Clipped wings for better roll
Futaba S 3010s {4} on primary flight controls
Futaba 3003 on throttle
Custom graphics on bottom of wing from Cal-Grafix
Good looking airplane with little or no cosmetic issues.

If you can build light, the AWX Edge will fly well on a piped OS 46. Ideally, and more simple, that ST90 you have would work pretty well, as will most any 90-100 4-stroke. All in all, the Saito 100 would make a rocket out of it! Mine had the Saito 125 and it was a rocket even at my 6800-foot elevation! Plan on 6.5-7 pounds with any of the aforementioned 4-strokes.
