The drop center appears to be behaving as expected.

I don't know about current on each motor w/o load, as two of the motors currently connected we didn't test last time. I'll see if I'll be able to take apart the boxes again tonight.

4amps higher is consistent both on the ground and on blocks.

Hadn't thought of checking for balanced drivers, thank you.

Thanks for pointing the battery safety issue out, I'll see what we can afford to put on weight-wise.

Gearboxes are toughbox minis geared to 8.45:1 with 6" wheels.
