I've run about a gallon through it now. Still tweaking the vbar tail setup, as it has a slow wag at the moment. Lowering the I-gain took care of about 90% of it, but I want to get rid of the rest. Mechanically, this is the smoothest tail of my fleet (links have been meticulously sized, etc.), so I'm 99% confident it's not a binding issue.
I'm pretty much clueless on tuning the engine. I haven't messed with the needles a whole lot yet, as I wanted to get a gallon or so through it before I started to tune. But this thing is pouring smoke and feels really rich at factory settings. On my last two flights, I tried leaning both the high and mid, but honestly I didn't notice much difference. I went about a half turn in on both needles, but I didn't want to go any further until someone with some experience can help me. I'm hoping to catch up with some of the nitro guys at my club in the next few days, so hopefully that will help. Right now, I'm at about 1/2 turn on mid and 1 1/2 turns on high from fully closed. This is on an OS 55HZR.
