One guy I talked to said the higher that is like 40c or 45c or 50c equates into more punch. He said your 25c and stuff with a 5000 mah battery is jsut alot of run time and doesnt provide alot of punch but on slippery tracks this is good so he uses those if that helps. and since your in toledo. Drive to cbus at hilliard fairgrounds. Awesome indoor off road track crcrc.com is website
