How about those heat stickers? they use on the Rotorway helicopter gear boxes and such I guess if the sticker gets over a certain temp it changes color or something like that.

Tony,

 

There are stickers that record the highest temperature to which they are exposed. I think I got them from Mc Master Carr. With the potential of overheating coils, probably due to the increased duty cycle, wouldn't it behoove us to install blast tubes to keep those little suckers cool(er) The ancient magnetos, in many installations had them.
