RE: os 70 surpass vs os 61 fx - fuel consumption
My Saito 65 gets 20 minutes from 10oz with reserve fuel left. And the lack of slime after flight is great. It may lose it's job to a 60 Webra, the plane could use a lot more poop. I'd like the Saito 100, not quite ready to spend that much at this time. I think the 65 would be nice in an LT40.
