RX 18 problem??

[madbadger]

hi everyone, just fitted a RX18 to my tam  KT, very easy conversion from the rx14 board, but on running the tank on grass, the left side track motor seems to struggle to turn the tank, right side is ok. The 14 board i took out was ok. Could it be a problem with one of the chips that provide drive? on concrete it seems ok but as soon as you put it on the grass and put some weight on, it struggles.
