Hm...after a battery worth of flight (8-12 minutes) my HD motors are also to hot to touch as BB_DF mentioned (I think it depends also on the weather conditions because when you (or the Ti) have to fight against wind, or it is very hot outside, the motors have to work harder). But it will be interesting to see the results after the measurements.

I bought the heat thinks (the green ones) but could not use them because they are to long? and stand over by app. 3mm, therefore touching the power connections and the capacitors.
You could cut of a quarter to shorten them though, but the combined weight of them is 37grams also!
