RE: Seagull Extra 300 - 75 assembly thread.
I got back to work today doing the fuel tank installation. I replaced the230cc (7.77oz)tank with a 380cc(12.84oz). That required modefying the structure to accept the larger tank. I would have liked to move the tank back a little closer to the CG but due to the location of the forwardwing bolts that was not possible. I suppose Icould have used a header tank setup.
I then moved on to installing the servos. All of the cutouts had to be enlarged to fit the Futaba servos and the servo tray was 1/8" too low.
