Been having some problems with my xxx-cr used it twice now and i just seem to be cooking motors, so bad that one of the brush shunts desoldered itself. I'm guessing it's down to the copper shims in the diffs giving a litle bit to much slip, I'm going to try it next week without them and just shim the diff on the outdrives.
Has anyone else had any problems with this?

What motors are you using, make, wind. also what gearing are you using and what batterys.

The diff shims won't cause your motor to desolder it's self there is some thing else wrong there, more than likely with the motor.

If it Helps My X-6 was desoldering both wires and the skotty doid at abot 4 mins ,, Turned out my Keyence was set to a drive frequency of 1.5 ( Stock Motor Setting ) Running a 12 SINGLE was just to much Changing the Drive frequency down to 8.5 its been fine HTH..........

there should be a clear silicone grease in the kit the cream coloured stuff is used on the thrust race think its refered to as white grease

Just noticed this on another thread is this correct as i didnt have any clear grease in my kit just the Creamy colored stuff so i used associated clear grease on both diff balls and thrust.

white thrust race only

that might be my problem then the diff may be slipping when heating up under load and over revving the motor. looks like i need to do a rebuild anyone used associated black grease on their losi thrust race.

I use the Losi clear grease on the diff balls, shims and plates and associated black grease on the thrust race
