David,
I started with 5 minutes on the timer with 3L of fuel. I had about a liter left when I landed. Moved the timer up to 6 minutes and still had about a liter left. My last run time was 10 1/2 minutes. I can fill to a little over three liters and probably get about 8 minutes flight time with the P-80. I've only got 4 flights so far. The 100+ heat out here is a bit too much for the airframe along with the heat from the turbine, so I try to get the flights in early and keep them short.
As far as the CG goes, the mark in the blueprint is wrong. It's at least an inch back farther. I worked the CG location with my dad and there are additional factors he believes the designer did not factor in. If you do the CG per the plan it will come out nose heavy. It will fly, but you are risking a difficult landing by running out of elevator throw and a higher landing speed. My jet weighs 21.3 lbs dry. It fly's heavy; it's noticeable in the air. It also needs power through the turns much like my Rafale with a P-120. So, you can go back some on the CG by easily 10-20mm from 122mm.
The other thing that surprised me was it's really hard to see it in the air. There were a few times I could not see the wings, which could easily cause you to second guess your self going into a turn. It’s much worse than my Rafale with the blue/gray camo scheme. I'm going to look and making some adjustments in the coming weeks, possibly adding a smoke tank too. If any of you guys have questions let me know.
