There is no better just different. Nitro can run forever till you run out of fuel in your bottle or compression in the eng but you need some one to fill & tune when your on the stand.Eng & fuel get to be a pain & expensive.
Electric needs no pitman but can only run for short races until a quick change batt tray comes out for consumption then you'll need a pit man again & electric components are very un reliable.Electric components get to be a pain & expensive.
Nitro wears out & must be kept tuned.
Electric just stops working at random times.
Back to my first sentence,if they could make electric components that work as long as a nitro motor electric would be better in so many ways,but like I said for now no better just different.
Try & have fun.
