It will spin an apc 16x8 at 9000rpm, but its not the most reliable engine around. If the plane calls for a 120 the OS 120AX would be a much more reliable choice.
The 1.20 AX is a nice engine, but you could almost buy two Kangke SK 1.30A engines for the same price!
I'd say, if you're a Super Tigre fan who's experienced with breaking in and tuning the big cats, then stick with your original plan and buy a G-3250 like you originally intended. Horsepower ratings on glow engines are pure nonsense, and the old saying goes, "there's no replacement for displacement!"
If you're more in the mood to shop around and see what else is out there, Hobby People is carrying the Mark line of engines by Moki. You might also want to check out the Aviastar engine line carried by Sig at their website
www.sigmfg.com - the Aviastar line includes 2-strokes in the 1.2, 1.5, 1.8, and 2.0 cu in size range.
Good luck, and good shopping!
