OK,
I changed the pitch curve to have 10 deg top pitch and ran it for awhile that wat. It still seemed to loose a little on the top end, so I made the needle changes that Bill talked about and tried it again. It is much better now. t holds the 10 degrees with no problem, and flies really well. I have a half gallon through this way so far, and the plug looks really nice this time, a nice tan look to the electrode, and no real big carbon build up yet.

I did however notice that once the tank got down to about half it would run a littel stronger. Does it take this long to get the engine up to temp, or is it just starting to run a little lean from the level of the tank being low. I usually stop at about half tank (10 minutes), but a few time I came in a little later than that and the engine was running a lot higher at hover than when I started the flight.
