Heat aside, you might also break the shaft on that poor little novak motor. If you want to keep it cheap, go with a Mamba Max and Feigao XL motor. For 4S, I'd recommend either the 8XL or 9XL. I'm running the 9XL and am more than satisfied with the performance.

I also just ordered the Monster motor mount for my 8ight. I know that I already have mine up and running, but Mike's is so purdy.

Now that I've just realized that I'm posting in my own thread, I'll update on my 8ight.

I got the Quark back into my truck. I also wired up a bank of six extra capacitors to in an aluminum block. I mounted the Quark on top of the aluminum cap block and the mounted that on top of a 1/4" piece of aluminum plate mounted to an aluminum standoff that mounts to the chassis. Last night, I ran the 8ight pretty hard on 5S for a few minutes and the Quark got up to 130*F. That sucks. I'm going to have to get it out on the track and see how it holds up.

The only reason I got a Quark was so that I could run a Neu motor. I may go back to the MM if I can get a Feigao to run under 200* for a 30 minute main.
