If you made any Mods to your 120sr - post it here.

I bought some heat sinks for the main motor of my 120sr. I used Zalman ZM-RHS1 VGA RAM Heat Sinks. They have self sticking thermal tape and fit nicely on the motor. They come 8 to a pack and you only need two. My motor used to get really hot in just one 5 minute flight and I was afraid it may overheat. After installing them, the motor was just warm to the touch after a 5 minute flight. Here is a good place to buy them: http://www.frys.com/product/5591560
