Thanks for pointing out those threads. In my setup, the aluminum prop adapter is very smooth, no vibrations at all.

After doing a bit of reading, it appears that reversing the shaft is not necessary. Look at imsofaman's post number 8 in this thread:

"Hey guys.....I think you are correct about the shaft bending. I actually changed my set around back to the stock set up with the axle mounting kit for that motor. One thing that I discovered was using the mounting kit for the motor...the aluminum shaft that bolts to the front of the motor is very solid. before...doing it my way with a modified shaft....I had vibration on the prop. with the aluminum axle....no vibration...solid and smooth. "

So I must have guessed wrong, apparently the aluminum prop adapter does not have a bore to accept the reversed shaft. It also appears that reversing the shaft requires disassembly of the motor - and perhaps some difficulty removing tiny allen screws.

If I were you, I would do what ever is simplest. I like the radial mount since the aluminum prop adapter works great (even if you have to hand ream the prop insert). You probably can't go wrong with either a modified Ikarus mount or a plywood mount. Too bad that MJP can't ship to Israel - we are spoiled here in the US - low cost mail order shipping is almost always available.

Good luck,
