I own all the kit you guys mention and I must say that building the Phaeton was extremely frustrating and ths GP Super Skybolt extremely relaxing, everything fits and the plans and instructions are great.

My favorite bipeplane is the Skybolt, awsome flying machine if power properly with a good 4 strokes how it should be.

The Ultimate and Hog Bipe are also a nice build and a nice flying airplanes; as with any bipeplane you must, I repeat must fly it down when landing, you must keep some power until the plane touch the ground, no much glide envelope with a bipeplane.
