We have a wave that goes straight without an issue. But the turning is very slow and wide in both directions - it can't really make a sharp turn because of this.


We noticed by lifting the machine off the ground that when we turn right on the wave the right wheel/motor goes slower then the left wheel/motor - in opposite directions as per design of the unit.

We turn left. Both motors seem to be going the same speed - but still very little power - in opposite directions as per design of the unit

Any idea what might be wrong?

Thanks.
