As alot of people are Im thinking of going to LIPOs. Im running 8.4 Volt 7 Cell NiHm packs right now. My question is, if I do switch to lipos will I need to get 11.1 Volt packs rather then 7.4 Volt to see a increase in performance? From the way I understand it the only pro to switching to a 7.4 volt lipo in my case would be weight? Am I out to lunch or is this right? Thanks alot guys.
