I'm about to maiden a Byron F16 with OS 91/Byrojet setup this weekend. Plane came out at 15 lbs dry, with CG at 3.5" infront of engine formers per instructions. That required a pound of lead in the nose to balance. Questions:
1) Does that seem right that much lead is needed to balance this bird. Plane is a bit heavy with fiberglassed wings.
2) Is the bird balanced with retracts up or down?? Instructions do not make that clear.
Thanks for any help.
Since the main gear shifts to the rear in the down position, and the fuel tank is forward of the CG. I would balance the plane with the gear down with empty fuel tanks.
