MasterAlex, good luck on the Hog Bipe build. It took me about 8 months, however I had a lot of things keeping me away from the build...like babies! Flies like you would expect it to, and then some.
Just to warn you... There are a few people on this forum that will insist you put a 4-stroke motor in it. I've never heard or the "Biplane Police" but, they could exist..
Just to warn you.. 4-stroke, or take you chances...
I took my chances and no one has a warrant out for me yet! [8D]
