AndyMark Nanotube gearbox issue

[Jonathan Norris]

We put together our nanos the other day and saw some binding. I found two main issues, first we installed the CIMs with two washers before the pinion gear, and it seemed that when we had the gearbox upside-down the first stage large gear had enough slop in it to bind with one of those washers, we removed one of the washers to solve that problem. Then we still saw a little binding, I noticed that when I loosened the CIM screws a bit there was a good amount of movement in the CIM mount, I pulled the CIMs away from the other stage before tightening it's screws and that got rid of all the binding. They defiantly take a bit of working in, also make sure that you grease your gearboxes... the number of teams I've seen without greased gearboxes...
