I am plan building a BK Flyer and I second the comments of William M. It is my seond plan build airplane, I previously plan built a CX4 Thatcher. I build for the pleasure and the BK Flyer has the best detailled plans ever. Bruce King is a gentleman and is also very eager and available to help.

This kit has what are probably the BEST plans ever drawn up for a homebuilt aircraft. I have been in aviation since 1976, and I have seen hundreds of sets of aircraft plans, both production and homeguilt. This is the best set I have ever seen! It is simply stunning! EVERY SINGLE PART is drawn out and dimensioned fully. There are also numerous assembly diagrams, and when you buy the plans, you get access to a photo-site that has over 17,000 (Yeah, thats right! Seventeen THOUSAND!) photographs showing virtually EVERY step in the construction process. Both the plans and the photo-site are organized by ATA code, so that EVERYTHING about the flight controls, for example, is in chapter 27. In addition, there are materials lists that cover every single piece of hardware and every single rivet and bolt used to build the aircraft. There are also pages of cutting guides that will cut your expenses, by helping you use EVERY SQUARE INCH of the aluminum you buy. Every piece you cut off of the part you are working on, is used for another smaller part somewhere else. If you are a big guy (Over 6 tall and over 230 lbs) this is the airplane for you. It will fit you perfectly. And even with your weight, you can fly with FULL FUEL and FULL Baggage. I am one of the early plans buyers, and I was struck by this aircraft design from the first time I saw it at Oshkosh. It is REALLY well-designed, and the designer, Bruce King, has spent YEARS on the drawings and photo builders manual. Google it and see if you arent as impressed as I am!
