I have recently had to cut the body shell to allow more airflow to try to cool things down.

Does the fan not keep up with the heat then?

I have an old SS5800 novak brushless and I had to fit my own fan on that to stop it cutting out, I thought these new ones wouldn't suffer from cutting out. For 2007 I'm going to move away from brushed altogether and so will be looking for a new brushless system, torn between Novak & LRP might be worth waiting until the end of the year I guess.

2007 better see the end of silly rules such as stopping ‘BRCA approved’ Brushless motors at nationals
