I wouldnt count on the 120s. I think were up to 4 events without losing one but thats a record. Interestingly enough one is mounted with limited anti-vibration mounts (never gone wrong yet) the other two are bolted to the chasis where we get the most problems but these two are for the drive and the current limit altered to 70Amps.

You will have more problems dealing with 4QD when (not if) things go wrong and when all our spares are done for we will try a Robotech. Weve been charged twice now for repairs when the boards still dont work after they came back fully tested.
