You guys are silly! come on, are you overlooking the most simple things just to call each other women? Real Men dont call others things.
On the topic of spur gears on off-road vehicles, like the B4, there could be a few things you are doing wrong. just check for these things:
1. make sure you have proper spacing between spur/pinion. Use a strip of paper, and place it between the two gears. then secure the motor. the piece of paper will give the correct spacing/mesh of the gears.
2. make sure the slipper clutch is set properly. stripped spurs are a common sign of an over-tightened slipper clutch.
3. inspect the pinion gear itself. see if the teeth are deformed, or worn out. they will look shiney, and sharp. these can also shred spur gears.
4. Inspect the motor plate. see if it may be bent (like from a hard landing on the motor). a bent motor plate will result in an angled pinion gear position to the spur, and can strip things too.
5. try turning the Expo on the esc down, or just try to "ease" into the throttle. slamming the throttle will stress the transmision.
6. make sure the motor screws hold the motor in place. loose motor screws will change mesh, and cause stripping.
I hope that helps! cheers!
