RE: Fuel comsumption for nitro engine
IBFN you must be able to get fuel below cost. 1/10 scale nitro normal fuel tank is 75 CC or real close to it. At $19.00 for O"donnels 20% and the max of 50 tanks per gallon thats 38 cents per tank. Not bad all things considered. 1/8 scale buggys use 125 CC tanks.
Easy to figure, 3,785 cc's per gallon. Divide by tank size to get tanks per gallon and divide fuel cost by cost per tank.
Engine size is a major factor in fuel use, but driver trigger finger and the conditions the vehicle are running in also play a major part.
For me, 1/10 scale racing, it depends on the track size and traction. Anywhere from 5 1/2 to 9 minutes.
