Hi, I believe I have my sh .18 engine pretty much tuned in now but am curious as to how long a 75ml tank of fuel should last. I am using the buggy in a car park, not too large, so never able to get 2nd gear, however I have a nice line of smoke from car and acceleration makes the front end rise on the suspension and no bogging or cutting out. I fill my tank right up, after 8 minutes of running 1/3 of tank has been used, making a tank last approx 24 minutes. Is this about right?
