Silly little update for progress on HardWired II, too -

Reverted back to 2WD till I can replace one of the faulty gearboxes, and still using the old chassis as a kind of test platform for the new electronics. Practically everything is new, BotBitz TZ85As, those two drill motors, the wheels (which do need fixing, one of the hexagonal nuts in it has come loose and just spins, so I need to glue that in... somehow. Also running on the Spektrum DX5e and AR600 now, I seem to get less power to each side when I mix the channels which is a bit odd. Failsafe is also a tad dodgey too (everything stays put instead of resetting to neutral) so I may need another receiver, but I don't think they're too expensive for a Spektrum compatible one.
