Picked up a Sig Hog Bipe at a sale this weedend. The plane is completey built except for motor mount, servos, balancing, and maiden. Unfortunately no manual was included and it's not available from the Sig web site. I emailed them but no response yet. I need recommended CG, throws, recommended servo type and placement in the plane. Also the fuel tank moves fore and aft. I assume it needs to be tied down or a wood support added to the rear of the tank. Any help would be greatly appreciated.

The person that built the plane did an excellent job it's beautifully built and covered. He was recently moved to a nursing home and is not in good health. He never got to fly this beauty and I intend to be certain that it's finished right and survives the maiden.
