hi i have the k1 it keeps riping the spur gear to sreds can anyone help thanks

[wrighty]

Make sure your pushing down on motor when meshing and tightning also make dure the recess in the chassis is clean

[mattr]

If you are ripping the spur to shreds, you've either got the motor and main shaft misaligned. I.e. not parallel. Or you haven't meshed the pinion/spur correctly. (Or possibly the wrong pitch pinion)
All are easy to fix.

Or your bodyclip retaining your battery strap is hitting the spur gear...
