Well go t two more flights in yesterday. The foaming was better but the new tank location caused throttle pushrod issues. Called Dub Jett today and ordered the 6 oz short tank. We talked about my setup and he thinks my header pipe is too long by as much as an inch. He felt that I should be getting 17.5 to 18k with the 9x7 apc so when the tank comes I will be doing some cutting.
The launching system continues to work great and has been very helpful to safely anchor the plane while tuning.
