  • Sorry about such a delay i didn't see your comment, No they are not for stock 3dr motors.  they we new bearings for my whole traditional heli.  but if you go to bocabearings.com they can make any size bearings you want.  they will also upgrade you to ceramic if you're willing to shell out the cash.

  • Are these for the stock 3dr motors?
