Hello All! 
I decided in late March to build a Sig Hog Bipe Kit that I've had for a couple years now and am very pleased with how she came out!
Covered with Sig Koverall and painted it using Behr latex paint and went over it with a coat of high gloss polyeuathane. Put in a Saito 1.00 for power and only have to finish up the final control surface connections to the servos.
Here a couple of pics. I will post the maiden flight report - only if it's a good one mind you[8D]
Lets keep building and flying !!

Good job! I've been flying mine for over 5 years. Love it! You might want to move the landing gear about 1/2" forward of the stock position if you are flying off grass. It has a tendency to nose over.

Looks good.
You'll discover that biplanes always get the most attention at the airfield.
Custom or stock, makes no difference, people are always curious about the bipes.
Good luck, and happy flying.

Thats a beautiful plane, i have one ready to cover just have'nt had time to finish it. I see you have a saito in it, what size did you put in? I have a couple of 72s and a 82 i think it is i was going to put one of the 72s in it. Let me know which engine and how it flys.

Maiden the hog last night.
It is a great flyer. I have to put a little more weight in the front end - there is 3oz up front now.Probably needs @ 1/2 oz.
It's not so much tail heavy as I believe the top wing might not be at 0 degree incidence. Landed beautifully and the Saito 1.00 pulls her along nicely.
First time maidening and flying a bipe. Loved it!! [8D]

WCB & SeamusG - I was nervous as I've never flown a biplane before let alone maidened one but she is a nice flyer for sure: Great job on that hog by the way SeamusG- My pilot does make the plane look complete - I've had ARF's, kits and scratch builts and it has been more " exciting" to fly a kit or scratch built by far!!

<span style="font-size: small">For those of you who've completed your hogs, what method did you use to balance. I have a great planes CG Machine, but I can't see how it's possible to balance using the top wing per the instructions unless you place planeupside down on the balancer. Also did youbalance at the 3 5/8" per the recommendation. If so, how did it fly?
thanks!!!!</span>

I ran into the exact same problem you did. I had the GP balancer and found it hit the bottom wing. So.. I built my own balancer.
Picture #1. Some 1" PVC pipe and joints. The balance point is a simpt "T" fitting, with the base up, and a round headed machine screw fixed into the top. I sanded the ends of the vertical pieces a little so they would easily fit.
Picture #2. My Hog Bipe being balanced. Notice the marks on the top pieces, These are distances away from the balance point. A small square will give me distance from leading edge.
The top wing to the bipe is straight, so you should be able to balance anywhere along the length of the wing and have the same result. I had a piece of scrap balsa 1/4" x 1" x about 12". I laid it between the machine screws and the wing, so the balance point wouldn't punch through the covering accidentaly.
I actually like this balance a LOT better than the GP balancer. With the GP balancer, you're futzing with the measurers (the things that measure from the leading edge) trying to get them straight. Trying to move your plane on the balance points, etc. too much going on for just 2 hands to keep under control. This one is way easy. I hold the plane at a height so I can assemble the balancer within the wings, then set it either forward or behind the balance point. Next I grab the scrap piece and lift the plane and position the scrap and plane. Then it's really easy measure leading edge, to see where I'm at. I don't have to worry about knocking something out of adjustment as I slide the plane forward or back.
