It seems that you are going to be getting an electric, but a little info on Nitro-

In a 1/10 car, a tank usually lasts around 10-15 min.- And you don't have to recharge a batt; just refill and continue (for how every long you wish).
You can get into Nitro with only $200-250 dollars. With $300 you could have a nice little set up.. Whats your budget?

I find that with my Nitro trucks I don't have to worry about a battery dieing, even though there is some electric equipment involved.. Every other bash session recharge the RX pack (charge it when your cleaning the truck), charge the Igniter all night.. You really don't have to wait around for batts.

I did the electric thing for three years (still use the ones I have though) and than last year I got my first Nitro (now have three).. I have no plans on getting another electric vehicle as I find Nitro is a funner power source Have fun with whatever you decide to get and don't forget to break in that Engine! (if you go that rout).
