I’ve been doing some nifty things with my bushwhacker and haven’t crashed for a few months now. Because of that I’m wanting to build a 540 to learn more acrobatics but am on a budget. I want to do it on 4 cell but would need to buy the batteries and charger since my charger is 2-3 cell. Is there much of a power difference between 3 cell and 4? Will it limit what I can do 3d wise to have 3 cell?
