Hi Silent. We ran our first race at Pheasant Runn and we made 10 min mains. So far there is no cogging on the new Losi 8ight with the Neu 1512 1.5D. I had a 30mm fan on the MM. I have fixed a 40mm fan over the MM now and it runs even cooler. The motor with no fan never got over 155F. These motors do rule. I think it's better than the Plettenberg. I was running an 11/46 and could only hold down half throttle on the straight away. The tires I had were too stiff and I couldn't get enough traction. Here is a clip of practice early before the racing started.

As of now, the nitros do not want us to race with them. Go figure. We don't have any problems running with them.
