Weight for weight, nitro engines are way more powerfull, and as power is way more important than economy in scale engines, thats what will dominate the market.

Why don't they make the engines gasoline instead of nitro? Nitro is expensive and wastes real fast. Gas is not expensive and lasts longer.
you wanna try living over here mate! our petrol averages over £4.00 a gallon now.
