I have a SA100 in a 6.5 pound plane(Fliton 330). I have a VP20 pump and run C.P. 15% with a little caster--Run from a 14x6 to a 16x5 prop. So far I have about 1.5 gallons thru the motor (put about 1/3 gallon thru it on break in on test stand). I have been getting about .6oz per min from the 4th tank full on the plane. I have a 12oz tank and am going to switch to a 10oz tank. My flying style is 50% IMAC and 50% 3D. ---very happy with this mileage on cheap 15%.
