60T Lay-shaft gear issues.

This one should go to Chris from at MA. The 60T gear is obviously larger than the stock so it creates several issues.

1. It pushes the motor back far enough that the bottom motor plate won't line up with the holes. There not much room to enlarge the holes or the slots so they must be taken clear to the edges and even beyond to get things lined up. Lot's of grinding.

2. It then pushes the nuts that hold the bottom plate on back far enough that they interfere with the fan housing. More grinding.

3. The Lay-shaft gear sticks out beyond the battery mounts. Needs almost a 1/4 inch of shims on each frame spacer so the gear won't rub the batteries. Not good.

The 60T will will work but not without all these mods. I don't like grinding on a new helicopter to make things fit...

Mine fit OK, as far as the bottom carbon plate. Yes I had the slide the fan back a little so the bottom motor ring would mount
I did have to stick 3- 3mm washers behind each one of the battery mounting post so that the gear would clear the Lipos but other then that it all worked pretty well
Even with the 58 and the 56 gear I needed a little more space for the gear behind the Lipos
I hope that helps

That should fit together O.K. Is it possible that the bottom plate is in backwards? Perhaps we should make the standoffs a little longer, I'll look into that.

No the bottom plate is ok. Took some filing but I got it done. The standoffs could be a bit longer but again, some shims took care of that. It needed about 1/4 inch all the way around.
