Rattle after shimming and testing the gears spin
 

Hello, first post!

So after shimming for countless hours following guides, I am getting a rattle when I spin the gears with the gear box in space with a couple screws.

There's no grease in the GB yet, and nothing else but shims and gears and bushing. I'm thinking the bushings might be too high since I left them stock (CYMA Gear box and bushing) so I'm going to take a look at that tomorrow. I might have to sand them down but if I shim right would that cause a rattle still?

Any help or advice would be appreciated. Thanks.

Whether you are boy or girl, you will understand that lube will help with friction issues ;)

Put some grease on the gears it should help with the rattling.
