Rodney, really? In my experience, the OS 160 FX uses less fuel than the Saito 180. My TT .91 FS sucks down the fuel about the same as my K&B .61. Maybe it's true for the smaller engines? Hmmm...
thanks
Interesting. I recently replaced an OS 46FX in one plane with a Magnum 52 4 stroke. On the same size tank (8oz) my flight times increased from 10-12 min to 15+ on the 4 stroke.
