Well here is an update Izzy came to visit yesterday and we built the rear gearbox while he was here and when he left I finished the front gear box and installed the servo and this morning I installed some electronics and took it for a spin. Sorry no build pics since I built it in less than a day but here is a video of the test run.

I will try and get some pics of it later all but the rear gear box because I don't want to disassemble it just for a pic.
