Interesting Murphy's law. My
Robbe ESCs say that will shut down durrent if the motors are overheated, don't
know if that solves teh problem. It did shut down the power once, when I was
testing under teh sun during a heat wave.
Once, in the older tankette, a pebble got
stuck in teh drive wheel, the motor stalled, I kept pushing, and the
plastic covers of teh thin (back then) cables just melted (together with teh
corresponding switch), exposing all of the brass wiring inside. Nothing
happenned to teh cheap Chinese motors. After that I changed all of my wires
to thick, 4mm dia. infalmmable, cables. You say tests, trials
and errors, by ignorants ....... I;ve abused them so much I owe shear
luck. I prayed so hard
on my way back to the shop that day.
My first RC tank, is all steel, 10 kgr
heavy, and runs on two cheap drills, 7.2 Volts. Once, I saw smoke,
and thought the motors burned out. but no! The motors had gotten
so hot that the little plastic and paper tags on them that say the firm and
voltage, actually burned ! Not the motors though.

. Both occasions could
result in high amp draws that will fry the electrics. That's what you use
your fuses for, to protect the rest of the system.
A lot of engineers will confirm that Murphy's law dictates
that the entire system will protect your fuse however :-)
