hi guys

am i the only one getting VERY poor milage from my saito 82

i have 30 years model flying behind me but cant solve this one.

it is in a YT Rush and both top and bottom end are leaned correctly.

bags of power and runs superbly.

OS 4 stroke plug, coolpower 15%, 14 x 6 prop.

no leaks, and the tank IS filling fully.

7 minutes flying only without risking dead stick, spending most time between idle and two thirds throttle.

i recently fitted an OS 90FS to the airframe and easily got 15 minutes but i need the OS for my Hype.

do i have a problem or is it just a feature of this engine?

regards larry3d
