Thermistors are only an issues in flywheel mods, Spud. Presumably, they provide electrical overload protection for the motors. But in reality, they're there to prevent people like, well, US from simply putting more and more batteries in our Nerf blasters and creating unsafe conditions like, umm, fires and shtuff like that.

A thermistor is really just a fuse, aka a Circuit Breaker. Same as the ones in the electrical panel in your basement. You draw too much current, and POP, they cut the power. But unlike the circuit breakers in your basement, thermistors reset themselves after a few minutes. (It's a heat thing really. When they cool down, they switch the power back on)

A lot of flywheel blasters can be upgraded from the stock 6 volts to 7.4 volts, without any problems with their thermistors. Throw a couple IMRs in your blaster and don't give it a second thought. Beyond that, thermistors are going to be a problem. Above 8 volts, they'll cut out at the most inconvenient times, and leave you with a dead blaster for 3 or 4 minutes. Experienced modders remove them entirely.

Thermistors ? What thermistors ? We ain't got no thermistors. We don't need no stickin' thermistors.
