I had to post this in here and actually need to post a pic or two. My nephew bought my old Mojo 60 from me and insisted on putting his new OS 1.20 AX 17x6 APC on it despite my advice. Well, long story short, we cut 2.5" off the nose and mounted the AX using a Macs header and alum. hairspray can approx. 12" long with two stingers. Needless to say, the throttle transition is instant and it will accelerate vertically at a very fast clip @ 1/4 throttle-we laugh every time he hits the throttle like little kids!! Oh, the plane weighs in @ 5.75lbs. and still floats in like it did on landings when it had my Saito 100. I don't think he has come anywhere near full throttle yet and a 10oz tank will give him 20-25minutes with some to spare since he flys at such a low throttle setting. It actually has worked beautifully.
