Update:

It was really hot out here in Socal at the end of June, but the track is going to be closed for a few weeks so I wanted to get one last weekend of practice to stress test the Tekin motor (and new rotor). It may not get as hot as some places but the the air temp was 106 degrees and the track surface was 135 degrees, so this was a good test on how the battery, ESC and motor would handle the heat. I put three 4s Neuenergy packs thru, I dropped down a tooth on the pinion because of the heat (47/14T). Max temps on the motor were in the low 180's and the Battery hit 110. Performance was great the weather was not.

Been a while so I thought I would pass on some updated info. Still super hot at the local track recently, air temps 106+ and ground temps 140 degrees. So I got some extended run time in during the day to see how the electronics would hold up. The Tekin T8 and MMM motors held up great and temps were decent (never got hotter than 175 degrees). My MMM ESC handled the heat fine, but I did have a problem with the fan, it was working intermittently. I always check to see if it is working when I first turn on the ESC and the fan was not moving. I removed the fan and tested it and it was indeed dead. I have several MMM ESC's and this is about the 3rd fan failure. It is a pain to remove the ESC, take the case apart and remove the fan, so I decided to make it a little easier. I don't recommend you do this because it could void your warranty, but I bascially attached the fan to the outside of the case and ran the wires directly to my rx so the fan was on all the time. This setup allows quick replacement of a broken fan, you can tell right away if the fan is dead and it runs all the time, which keeps the ESC cooler. Just drilled two holes and used two 3mm screws to hold the fan down.
