After a very long lay off, I have started racing again. I have just recently switched from a 10.5 Tekin to a 17.5 Tekin (Tekin RS esc) because the club has just started a 1/10 buggy "blinky" class, which is much better suited for my basic driving skills. The car is a mix of B4/B4.1 parts, and handles very well. I am currently using 5000mah 40C batteries. Timing is maxed, current gearing is 34/75, but I am going to continue to push the gearing until I start hitting safe max temps. My question is, I see that Orion make a 90C battery. Will it make a noticeable difference, or are the 40C sufficient? Thanks
