Losi E-8ight

I put in that thicker center diff fluid and it is doing much better. I also got in some of the Ofna diff lock and the 120,000 stuff as well to play with tuning it.

I also reprogrammed the esc and I noticed that I was getting some odd results. Turns out I had the radio set to reverse so I was getting 50% reverse throttle limit while going forward instead of backwards. It runs quite nicely now. :D

That being said, on the 15t pinion and I don't remember the spur, the motor got HOT. 200+F hot after I measured it 2 mins later. Burnt my fingers pretty good too.

The esc was about 120ish and the batteries were around 85F, I don't know ambient temp.

What should I be looking for here, bigger pinion or smaller?
