RC10 classic with brushless 

Yes tighten up your clutch on the Spur Gear “the big white gear”

Tighten the slipper clutch my losi dose that even with mod brushed motors

I recall there was a grease meant for the balls on the slipper clutch/ differential. Without the grease, obviously it will slip less but it may burn out the diff.

slipper to loose bud, run brushless might as well use an slipper eliminator

Tighten the slipper clutch. That's all it is.

Slip differential needs to be tightened. It's the nut with the spring on the big gear opposite of the gear thats on the motor shaft

Adjust your slipper clutch

Definitely a slipper clutch adjustment. Its too lose for all that brushless power. It should only slip for about 6” to 12” depending on your track. This is also your torque setting so dont over tighten or youll lose your tires 🤭

Tighten the slipper clutch and the diff

Is not designed for brushless system

It’s fine

adjust your clutch

Well i think it sucks pilgrim

Had the same issues and trying to work through it. My stock spur gear was destroyed after a few runs. Waiting on replacements now. Try changing the gearing or the settings on the esc
