I'm not sure exactly how much run time I get, but I was getting more than FreeRide w/ his picco .26 at the pizza party.
I use a JP-3.
You can't really use that to compare. The thing was SUPER rich. I was contemplating putting a return fuel line on the stinger back into the tank. I was getting almost twice as much run time when I re-tuned it at the next practice. Iwould say that robs motor is on par fuel wise with just about all of the other .28 sized motors.
