An idea for future CC ESCs

[Dagger Thrasher]

Hey all (especially Castle guys, if you're reading this). I've just had an idea for a possible future feature on your ESCs. If it's already been thought of then forget this, but I thought I'd get it out there.

Why not have an optional, external temp sensor for your motor that hooks into the ESC? You could just have a temp probe (probably just a thermistor) that's thermally-epoxied to an aluminium motor clip, which could fit around most smooth-can motors much like the clip-on heatsinks you can buy (for the Castle-Neus, it could fit near the rear endbell). Then, just have a simple 3-pin port on the ESC which the sensor can plug into, and the ESC could monitor the motor's temp and go into shutdown if it approaches 200F? Maybe even have the cutoff temp adjustable.

It just seems to me that a relatively simple feature like this could save an awful lot of (perhaps inexperienced) people from damaging and demagging their motor...and even save a few ESCs as a result. Obviously it'd require a hardware change so would only be useful for future ESCs, but it seems like a sensible idea to me. The Novak sensored setups have a built-in temp sensor in their motors, and it only makes sense to have a similar system on our much more powerful systems. Could save a lot of warranty claims, and would be a nice failsafe to have in case your motor suddenly heats up due to some other problem.

Like I say, apologies if this has already been considered and discarded. Thoughts?
