Lots of good info here in terms of speed wise it seems electrics have caught up with and overtaken nitro nowadays,for racing i still think electric still has the advantage for instant power to nitro as they dont need to build up power and as runtimes ive seen people pit in and refill several times for fuel while lipo owners carry on in 30mins races.

Both have there advantages some love the smell and noise of nitro and others like the power and easiness of electric.
