Good video Doug. Nice track system overall and great looking moc!!

Thanks - the tracked version is much easier to drive & steer than the wheeled version of my MOC.

Turning on the spot problem:
Seems the weight of the rotating structure is causing the tracks to bow inwards slightly and tracks start to rub on the under carriage side frame.

Have to find away to prevent this.

Update:
Now fitted more bracing to prevent the top of track units bowing inwards due to weight plus steering now uses an L motor.
Battery box mountings modified so no longer have to remove both track units it to fit new batteries. 
Return track rollers changed from 24 mm dia. wedge wheels to 18 x 7 narrow rims as track tension too high causing cogging.
