Tetrix Kit Possibilities

It might help to contain the motor(s) in a diving bell an run chain drives to the rotors. The greatest issue might be finding a suitable fluid and a vessel in which to contain it.

I'm not crazy, I just like to think .

Explosive/flammable in great amounts?

Mineral oil won't explode; it isn't nearly volatile enough. Its flash point is well above what would make it a flammable liquid. Mineral oil will burn (and produce nasty smoke) if you put it in contact with something hot enough for long enough, but that's true of many substances.

Perhaps you're thinking of mineral spirits?

DOH! Of course I was thinking mineral spirits

If it's an inductor that blows, that's an easy fix provided I know enough about it (size, resistance values etc.) to replace it.

Also, I didn't know those motors will blow out under a low load at a high RPM, it seems strange unless they were running them full out/overloading the motor. In that case, yeah. There's actually a forum where I pulled the exact specs on the power of the motor. Again from my post above, running them at maximum power seems to be the way to go.

Quite a few FRC teams had a lot of trouble finding those inductors. I think someone did find a pretty close substitute; it's slightly larger than the one there. (The other option, at $30 a pop, was to replace the motor.)

I'm pretty certain that the FRC teams were running at full power to go up the pole (the entire idea was to get up the pole as fast as possible). If you have a heavier load than the pole-climbers, you'll almost certainly blow out inductors, repeatedly.

It sounds like a case of overloading the motors weight wise or having them reach a stall condition (aka 0RPM) which I expect draws too much current?
