The primary problem is that you have 236 gallons of fuel in each wing. 472 gallons weights approximately 2832 pounds, and that is about half your weight of the aircraft..
The second problem is that you have 500 pounds of dead weight in the nose of your airplane making it nose heavy.
I reduced the fuel, took out the dead weight, and even changed the main wings to flat-bottom for extra lift. It can now fly level, but you still need to add quite a bit of trim to do so. BTW, trim controls are 1/4/7 on they keypad.
