I just maidened a 600E T-Rex after flying A Raptor 50. I am new to the E scene and other than the high entry fee into the battery game, I for now prefer the E to nitro. At $30./ gal of 30% x 10 gallons you have burnt the cost of a battery. The big benny to E is no mess, no smoke, and a lot less vibration which in time translates to maintenance. The E is quiet, i can fly in my back yard without pissing in someone's corn flakes. If you are a big time crasher( which I was while learning) then nitro is the way to go, much less in the repair bill dept. I do not think $300. 6cpacks like the crash scene too much. Pay me now, pay me later, you will pay!!!!!! if you want to play.
