Re: Real world RPM

Ok, I am probably out of the box a little and will probably get harrassed about it cause I dont run cans. Have a brand new DA 150, not even 2 gallons through it yet (almost). I am running standard mufflers with a 32X10 Meizlik. What RPM's should I be at. Ran it up the day I put 5 flights on it and it was turning 5400 on the ground. After flying I noticed a ton of exhaust splatter under the plane when I was cleaning it. Should I crank down a little on the high needle or leave like it is for break in. With it right now it pulls the plane around real good.
