Ok I wil tack the cost back. Yes in some ways Electric does cost has much as gass does. Batteries do not cost 120 a pack that ways to much to put there packs cost about 60 to buy then when u have them put to gehter there about 65 to 70 bucks. Electric there is less mantince then gas, to me gas as more mantince. I have talked to some people that have gas and some say they wiss they had a electric car/truck. With tires u go througth more tires in gas when u run stock electric they last longer even sometimes they last with mod. It all depends on what tipe of track u are racing on. I know u can run longer times with gas. I know people that have put like 1,000 dallors in there 1/8 scall buggys in and I have not even put out that much money in my electric cars/trucks. One thing too is that u do not need a pet man too and the electric is not a as loud as gas is, so for me I have to say electric all the way.
