My .45 Evo runs like a bat out of h*ll no matter what the weather is. Fog, humidity, dry weather, it doesn't matter to that one. I never adjust it unless I'm just curious. I've learned to leave it alone and keep slamming the throttle open a lot if I fly my trainer. It never quits, hesitates, or bogs down.

About my .46NT- that engine had more power on the first takeoff than the .46FX and TT Pro .46 that had been on the same plane. A couple of us who were familiar with the plane were surprised. The NT keeps getting better and better like Ed said. I would put the .45 on another plane with an APC 11x7 if it weren't so heavy. I think it is around 7 ounces heavier than the .46 NT.
