That would explain the problem with the gear's
Do you know someone that has a Lipo with the same connector's that you could borrow long enough to see if it runs better? Please check the speedo to make sure that the Lipo cutoff is set.Also have you replaced the spur and do you have a couple of different size pinion's to try?Do not get real aggressive with the gear ratio until you see how it run's out.Am I missing something else guy's?
That 6900 is a LOT of motor in a Rusty,so easy does it,it is better to be easy on the setup than to start shredding part's.
