Guys... question...

My OS 70 II will not hover my U-Can.

Right now I'm on Cool Power 15% with an APC 14x4w. I'm running the Uni-Flow tank setup and it works like a dream. I have my CG at 6 1/2 " (yeah... I'm crazy). No tach, but I'm running audibly rich. No scale, but I built lightly, and this is my 15th plane or so, and my first ARF so I know what I'm doing.

I'm going to do some needle tinkering today to see if it helps.

I know I'm not going to get .91 Saito performance, but the .70 should AT LEAST hover the damn thing.

In a slight (and I mean SLIGHT) breeze I can back it up in a harrier, but as soon as the nose goes up I start to lose performance. I would think it was a leaning out problem, but the engine note never changes, the plane just tailslides and falls. I know my idle needle needs to be leaned out, but my high speed is where I always set it up.

Here's my question: I have seen and heard of people running the 30% heli fuel in their Saitos, but how well does it work with an OS? I was told at the LHS by a man who is far older and wiser than me that OS engines can get a little cranky above 20%. Anyone out there running 20+% in an OS 70 that can give me some feedback? I think the 30% would give me the power I need.
