Thanks Bob, I'll try to richen it up a bit and see what happens.

As far as the tank goes, when i was doing initial ground runs, I had an air leak somewhere in the tank, so I took it out and replaced all the fuel lines. I made sure everything was in top shape in there this time since it was a pain removing the tank.

What does holding the plane vertically while running tell you? I did this once, and while going from idle to any other throttle setting, it seemed to hesitate and stumble a bit.

What I found really odd, is that the first flight of 2 days in a row were flawless, then the rest were not so much...
