More findings.

I ended up with two turns to the up on the elevator pushrod. The engine now ran funny so I inspected the tank set up at home. I have an r/c engine mount which makes for a deep tank compartment. The tank is a four ounce round plastic item and it sits way too deep or above the spray bar. I put a piece of half inch thick foam rubber in to even the tank center line with the spray bar. The winds have been too high early in the morning for a test flight but I did run it here and it seems to be better.
