Additional Information

Challenges Faced
Lots of fabrication and pre-thought bringing it all together ( Been over 6 months building )
Getting differentials to be just shy of spool like locked, yet able to turn w/o pushing.
Testing outrunner motor and gearbox combo for sufficient power/torque finding it more than enough for the task at hand.
Rear wheel steering utilizing front end parts at the rear & adjusting/aligning it all getting correct function as a FWS rig.
