Okay, lets go this direction. I have been flying my gas speed planes and all for a few years now. Last year I decided to get an electric just to keep in the truck and pull out and fly it in some off the wall place at the spur of the moment type thing-like at work or something. The cost of going or starting electric is darn near the same as going gas. When i added it all up, I blew it off and bought another plane!

Your going to need a few battery sets, chargers, speed controllers. One other thing is that it is easier to go from gas to electric than electric to gas.
