I've been looking at doing a shaft mod to maintain 4WD with a normal motor. I've almost got all the parts I'll need, but I've been thinking about the aspects of it that bother me. It seems most mods like like this have used a gear transfer, and it is usually pretty tricky to line up the gears properly. Even if you get the gears to line up, theres no guarantee that the next motor you try will. In the meantime I was trolling the xmod forums again and saw this post.

I was wondering what you mini-x people thought of doing a belt transfer instead of a gear transfer?
So aside from not worrying about gear mesh, you could also play with the pulley size ratios much easier than with gears.
The disadvantages would be potential breakage and belt slippage. Can you think of any others?
EDIT: Any idea where to get the pulley parts? The referenced thread used a VCR repair shop... are there any rc airplane parts that might work?
