Dropping down to a 7.4 35c  lipo when it comes in. Debateing on going even smaller like maybe 7.4 2000 mah 25c lipo. Your right I do have alot of power running in it right now thats why I cant open it up all the way, plus Ive got to get the computer usb from castel to program it the way that I want it to run. Right now its running on just factory settings but that will be changeing soon.
