Hi,

just before XMAS I changed my front diff for a spool in my losi XXXS tourer. I have since taken it for a run and now the car doesnt accelerate well.
I can hear the motor spinning up but I am not getting anything like the acceleration. At first I thought my pinion was lose but that is not the case. The
belt does feel a little loser so I have used the tensioner but to no improvement.

I was wondering if the belt was loose on the diff pulley but I would of thought I would of heard it skipping teeth if that was the case?

In addition to changing to spool I also changed by spur over which is 64 dp not 48. However, I am using the equivalant gearing I was when I was on
48dp.

Any suggestions would be welcomed....
