Taxi test
Posted: Sun Feb 19, 2012 11:42 am
Hi all,
Still waiting for my DAR to do inspection of N771ME Elite. He is coming next saturday now. FAA dragged their feet with my paper work last couple weeks, but all is a go now. Today only -10F but warmed up to 15F. I took out my airplane to do some run ups and taxi testing for the first time to get the feel of it. Good temps in this weather, 140 max oil with plugged off cooler, and 300 max CHT no matter what I did on the ground.
Raised the tail at about 30mph down the runway, the airplane is a little squirrelly but manageable, that is until I ground loop it. There was a 6 knot cross wind, which I really dodn't need at this stage of the game, but ok.
I uploaded a picture in the files section, Elite, finished.....
Everything is checking out good except for the brakes. They are very poor for some reason. The pedals are solid with not much movement of the masters when applying them, so I don't think air is an issue. I did pressure fill them from the bottom up through the bleeder. I tried dragging them around the ramp, they got warm, but not much improvement. During a run up I have a hard time holding the brakes over 1400 rpm. I did manage a static full throttle, with 76X58 Sensenich prop, I got 2300. I also don't have enough brake to kick out the tailwheel. I also run the 8.50 tires if that is any handicap.
Any thought?
Mike Betti
