If you want to control from the balcony, then range might be an issue. a decent transmitter might have a reliable 100M range, in idea conditions. But, if you're thinking about a car from a toy store, I wouldn't bet on it.

Electric will have limited battery life, and power. especially on grass. Without a battery-destroying fast-charger, you'll spend hours recharging for less than 15 minutes of driving, probably.
IC is where it's at. You get power, speed, and highly flammable fuel. You probably won't be allowed to legally store the fuel anywhere (nitromethane and methanol), and the noise of the cars will probably piss off your neighbours.
