The two alternatives I most like are the .75 AX and the Zenoah. The thing that worries me about those two choices are underpowering with the .75 AX and overweight with the Zenoah. I dont really care about hovering. I'm not much into 3D. I like precision aerobatics and have to take into account that I'll be flying at over 7800ft above sea level where engines get a considerable cap on their prompted potential.
G'day Mate,
How can you underpower a 60 size plane with a 75.
A 60 will fly it fine, but I ordered a 75AX yesterday for my 60 size Diabolo, it flew great with an OS 61FX, & it will be even better with a 75AX, & a 14x8 prop, if you get a 75AX please use the recomended props size, it is designed to swing a larger prop, than other 75's.
