I received the Losi motor heat sink today. It is very well made and has very large fins. It fits perfectly in my converted LST XXL and doesn't interfere with anything. What a difference this thing makes in motor temp. On the first test run on 4S, the motor ran at only 125 degrees. Tomorrow I will charge a couple sets of 3S and test running on 6S. Right now I am very pleased with this heat sink.
