Default Saito 30 RPM, post other 26-40 four strokes!

Just ran my twin engine plane with Saito 30's. Numbers were with 2" spinners, about 2200 ft. altitude, 55 degrees, running Powermaster 15% two stroke fuel:

9x5 APC = 12000 to 12500 (peaked)
9x8 APC = 9800 (seemed loaded down to much with this one... very finicky and inconsistent... if set needle for consistant high speed, (at about 9600), then low speed was too rich, even with air bleed backed out all the way.

Someone else put these props on there, I think the 9X5 is too small, perhaps the 9x6 would be ideal.

Anybody esle have any other small four stroke readings or experiences? Or any tips to get my 30's to idle better, and more reliably? I dread having one die, this is my first twin.

OS .26
APC 10x5 = 9600
Cool Power 15%

I have found this combo makes the most thrust for my GP .20 Cub

What are you guys getting for fuel consumption on the 30?
I'm debating an 8oz tank, but will stick with a 6 if it'll get me close to 15 minutes at WOT.
