Weight and Balance, Preliminary - 1 hour (455 Total)

After installing the wings I did a preliminary weight and balance calculation of the plane. There are still several major things that need to be added to the plane such as: prop, wheel pants, jury struts, and door.

Left Wheel: 248 lbs
Right Wheel: 234 lbs
Tail: 27 lbs

Total: 509 lbs

Assuming 200 lbs of pilot and 54 lbs of fuel (9 gal), these values put the center of gravity at 107". Rans specs the plane to have a C.G. between 101"-110". The missing components should not effect the C.G. too much since the nose wheel pant and prop should balance each other out and the main wheel pants and jury struts are right over the C.G.
