Dave,

I've got a Saito .72 on my Funtana. A couple of items. I normally check the high end by holding the plane vertically at full throttle for about 7 seconds to see if it starts to sag. I actually keep it just a click or two on the rich side. My high end needle is out just a bit past 1 1/2 turns. The pinch test also works (you pinch the line for a second and see how much the rpm goes up, or, if it just drops without first increasing, then your at peak or lean). I found helpful also the low speed needle adjustment. Check the low end by going to idle, letting it there then quickly accelerate the stick. If it hesitates or quits when you quickly advance the throttle, richen the low end. If it does not idle consistently (loads up when its at idle) lean the low end. I had to lean my low end a lot from the factory settings for a nice idle. Definitely run a fuel filter. I've fixed one that would not run right. I took the needle out and then pumped fuel through the vent line to clear the needle valve track.

I've used 10 percent fuel with excellent results in the Saito .72 I've run a 12x6 APC for extra throttle response on the 3D but I've normally flown the 13x6 APC.

Hope this helps.

Don
