My gear drives have been making these vibrating noise for a long time now, never been problematic, just annoying. Originally it sounded completely smooth and silent. It’s seems that the bearings on the wheel gear is vibrating whenever I apply the throttle. The pom wheel gears are not unbalanced. Any ideas on how to fix this?
If ur looking to replace them, I have gear drives for acedeck
