Wrong- how dare you question the word of a BL God!

Disconnect the motor from the esc, then try turning it on- you will suddenly find there is no noise at all. The motor doesnt need to spin to make the chimes, its the frequency of the current through the windings that generates a sound- its not done in a way that makes the motor want to spin. Trust me, or just ask BrianG etc.

Anyway, the onboard temp gauges with loops look pretty good, you just have to find a way to keep the loop around the motor (a finned can would be handy), and then you can monitor the temp at the push of a button, and record maximum temps etc with different gearing. Wouldnt like to recommend a specific brand, but Im sure a little searching around will yield answers- they are normally used on nitro engines, so thats a good starting point.
