I'm sure everyone who is interested in this discussion would love any pictures of boards and/or flaps stowed v. deployed , how they actuate etc. especially any that were added after build is complete. seems like it should be an easy addition.

Flaps provide lift and drag, so can also reduce the stall speed. However, the stock flaps per plans are too small to be very effective, which is why you will see most KRs with drag producing devices using a belly board. I did use flaps on my KR. However, the aileron bellcrank and cross cable between the ailerons in my plane is located in front of the rear spar. With that modification, I was able to use the trailing edge of the wing stub from the aft edge of the rear spar to the trailing edge of the wing as a flap making my flaps significantly larger than the stock flaps, which makes them very effective. More on my flaps at <http://jscott.comlu.com>. Mark L designed split flaps for his KR. He was also very pleased with the effectiveness of the flaps.

Has there been debate on the KR Net about belly boards vs. flaps? I'm getting close to committing an starting a build. This is just one of many questions I'm sure to have along the way. Studying plans and drawings now. Thanks for the help so far... It is reassuring to see so much great help available.
