Losi XXX-BK pulls to one side on acceleration

[Fiddybux]

Hi all,

Just wondering if anyone knows why my XXX-BK (not BK2) pulls to the right when accelerating from standing?

This seems more pronounced when I have a faster motor installed...which makes sense considering the extra 'oomph' that a fast motor provides.

Is this because of the location of the motor, being fixed to the rear standing out to the left slightly, as an unmodified XXX would be?

Or is it that the diff is tighter on one side than the other? It shouldn't be the tyres as these are all new. Dunno about the shocks or whether these can affect this sort of thing...they've been recently rebuilt and feel good and even all round.

This is a real pain at the start of a race because I either have to go-slow on acceleration or battle with the car to keep it in a (kind of) straight line.

Any advice appreciated.

Thanks in advance.
