i'd say nitro, speed is much better and people keep saying its more exspensive...if u keep it maintained and it might be around teh same...sure u hae fuel but it lasts a while...

to get a electric to go fast you will have to go brushless which is over 100 bucks...then upgrade servos, and electronis to handle it and gears...a nitro engine of high performance will be cheaper so i would say stick with nitro and keep goig...i am only 15 and will be turning 16 in october which means i need to get a car but i am using my bday and x-mas cash for that.....its always fun to have a toy to tinker with when your bored
