I got a chance to run the 60C 6000mah packs this weekend and I'm really excited about them.
I ran at the dirt oval track in stock 4wd late model. The car I'm running has a non-ramping ESC, and against a field of all ramping cars I was only 1.2 seconds off of TQ for a 2nd place qualifier..and that was primarily because of a bobble. The pack had all kinds of punch off the line and the speed was almost the same as the ramped cars...just insane.
Way faster than my other packs.
For those running bullets I'm noticing the connectors in the packs hold up much better than others as well; the bullet doesn't appear to be getting loose at all, where as some tend to 'break in' and the plugs will slide out much easier, these feel just as good after running it 10-15 times in a 1/8 eBuggy as they did when they were brand new. Very high quality.
