While I was traveling through Virginia I stopped at a hobby shop. I wound up buying a Sig Hog Bipe that was on consignment. It is beautifully built and appears to be in excellent condition. It has an OS.91 on it. It needs 5 servos (1 each aileron setup ), battery, and Rx. My question is: does anybody know where the CG should be? There is no manual with it. Any help or suggestions are welcome. Also..I apologize if this thread is in the wrong forum. I didn't know exactly where to put it.

Thanks,

Airroy

Airroy,
you have picked up a great plane. I am on my 3rd Sig Pig (the first I actually built myself). you will simply love this plane. the os 91 4-stroke seems to have been made for this plane. to answer your question, I have scanned that portion of the plans for you. plus the paragraph in the instruction book that covers balancing. hope it helps. and please post some pics of your Hog. or better yet, post it on fubar hill ([link]http://www.fubarhill.com[/link]) in the hog bipe forum. My current one is posted on page 5, black with yellow trim.

here is what you need to balance it.

Hog lovers...mine is on Fubar, too. Same one that's on this mini-pic. I'm going to go check yours out. PS, the 91 is an awesome engine, except I now run a 15x6 APC. The performance is unbelievable. I have about a 1:1 thrust/weight ratio and vertical is fantastic. He is right: you will love this bird! Mine has an interesting story behind it, too!
