Wow, thanks for all the replies so soon! I guess its not a win win situation for gas. THere is weight to deal with, and pure power. The exhaust residue is what gets me agrivated, but since im still flying my basic trainer for fun these days, its not a bad situation. Im sure in the future i might try gas because i know the companies will make it their top priority to keep making the gas engines smaller and smaller, and more powerfull. We'll see what happens.
THanks!

PS: Also, what extra equipment is needed to maintain a gas engine?
