My RC 18 MT started making a funny sound after i ran it on a pathway that have some sand on it( because winter is ending and the people put sand on it so people can walk on it.) and it was only for about 5-10 minutes then it locked up. I waitied a little and turned the wheels and it started moving again and I tried driving it and it was makin a different sound than it ussually does. I checked my pinion and spur gear gap and it made it sound a little better after i adjusted it. Anybody know what it may be? And I want to bring it to my aunts house on sunday and I want to make sure I will be able to run it...

Thx for any help.

RC ( I hope i said the pinion and spur gear as the right things.....):wave::wave:

Check those gears again. There maybe a small stone or piece of sand stuck in them. Just pick it out with a xacto knife and it should be ok. You don't want to run it like that since it will tear up the gear in time.

ok thx bud

It is possible that you got a small bit of sand in a diff either front,rear, or both. If so, you must open them up and clean and relube them or the gears will wear out really fast.
