BK1 LSA (Light Sport Aircraft)
- Tricycle or Taildragger, great flying qualities make the BK1 comfortable to taxi, takeoff, and land.  The stall is gentle and predictable, check out this video. BK Stalls and Slow Flight

The first BK1 prototype project, competed in 2004 was focused on proving the airframe design, building process, and flight characteristics. It was and still is a grand success, showing how a small, light, inexpensive airframe can fit a large pilot and fly long cross country missions with room for all the camping gear and luggage needed for the trip to the big show.  Click the button "Trip Reports" above for the whole story.
The second BK1 prototype focused on the the CAD drawings and photo documentation. They are an integral part of the building process.  Nothing was built until the CAD drawings were in hand, and thousands of photos were taken to document the process for builders. Easily drawing and documenting  process took 5 times as long as the actual building process.
