Not nitro either. Gas (or petrol depending where you come from). Nitro racing cars (at world championship level) can't be pull started either by the way, they use starter boxes.
anthony wise i think darkwing makes the most realistic rc cars on the planet ...( people inside that move) engines with super chargers that moves and rev ..) but there all like 1/10th electric cars ... to eaches own i guess .. but bigger and slower isnt better to me ... id rather have a small rc jet that goes faster than a bigger one thats more realistic ... i like real cars too / ... i just think no one builds good 5th scale parts .. how can 1/10 and real size dragsters both be faster than 1/5th scale dragsters ? ... i just think its parts .
