thought id weigh in here as im into rc cars myself, electric is defo the way forwards, a litre of nitro for an rc car is around 12-15 quid, more expensive than bloody petrol haha!
i have a hsp flying fish 2 drift car with upgraded motor + esc (brushless) just waiting on getting my lipo charger and battery, even with ni-mh batteries its pretty damn fast, considering my car is set up for drifting you can put normal wheels on it and it goes around 25-30 mph, when i get a lipo and the right gearing setup, it will be mental fast, few mates of mine have em too, we go out regularly, lots less noise than the nitro ones, so even if you fancied playing at midnight you could still get it out in the street and not bother anyone, nitro ones not so much, you would most likely have the fuzz called on you lol, electric ones are definitely easier to use and setup, if you have a brushless setup you dont have to bed the motor in like nitro or brushed motors, its a case of get it, plug it in, and go mental, will try an get some pics up of mine, my shell is battered and i ran thru dog muck so needs a little clean first xD here is my car next to my mates buggy type brushless
this is the only photo i have right now, will take some more soon, cost me 120 quid initially with brushed setup, iv since spent another 150 on bits, i.e batteries, spare wheels motor/esc, chargers, and i need a new shell soon haha
