Today confurmed my less cleanup theory. I flew the Saito 45 today for three flights and there was just a couple oil spots on the wing and none on the fuselage. With the 40 OS 2 stroke, I would have had to clean it after every flight.

On the idle issue. My Magnum 52 four stroke fell into this catagory. My O.S. 52 four stroke is just plane awesome at idle. It will putt along a 1800 all day and the when you jam the throttle, it jumps to life. Never had a stall or dead stick with it.

The Saito 45 is a different engine. I have never seen an engine that has such a wide range on the High Speed needle. The window is about 1 1/2 turns wide. I leaned it to day with a tach until it just started to drop. Richen it back to max and the keept going richer for just shy of 1 1/2 turns before it started to fall off a bit. I don't have the idle set really well yet, but it should only take one more day at the field with it before it is like the O.S. I'm guessing. I think my biggest problem on idle with it is servo related, not engine. I'll pull the servo an try it.

Bottom line, I would never buy another 2 stroke and might just sell off the one's I do have.
