Model Forum / Radio Controlled / Land Models / March 2005

1st check the gear mesh between the clutchbell and main gear, engine may
have slipped a bit.

If not that check the front center and rear diff joints (what the front
rear driveshafts go into) 4 of them, one may be loose.

If the above are good-
Worst case the ring/pinion gears in the front or rear diffs are worn
out. Start it hold the vehicle in place give it throttle the driveshafts
should not spin if one does with out the tires moving the r/p gears may
be bad.  Had you heard any clicking noise prior while braking or
accelerating?

I take it;   this is a newish model?   the engine stopped too?  engine is
not poached? can not turn engine over? no fail-safe involved? onboard
batteries all good? no small stone imbedded in mesh of any gears, clutch
housing or drive joints? brake(s) not seized?

Make sure the allen set screws on the outshafts are tight (including
the center drive shafts.) . I had this happen to me on my TQ. Thought
I had toasted the differntial. Come to find out that the allen set
screws had come loose just enough so the shafts no longer were set
into the flat part of the shaft (The set screw screws down into a flat
section of the shaft making the connection between the two.)
