Unique Characteristics of Jim's KR-2 - N891JF

The picture on the right is a picture of my instrument panel. I found the KR pedals at Wicks Aircraft and made fittings to make them into toe brakes. I use a sight gauge that I have measured all the way to the fuel cut-off valve. Everything is basic VFR with the radio from RST and a Terra transponder with mode C. My compass is mounted on the canopy so it won't have any magnetic interference.

I made my own wheel paints. This was a job, creating a plug and then the mold to pull the paints out. I have to tell you, buy them, don’t make them. I thought it would be a great speed improvement and it wasn’t. But the real reason I posted this picture was to show the way I bent the pitot tube. This works very well and hasn’t been a problem at any speed.

I listened to a number of KR pilots when I was building my KR and found they ran out of trim. I built my trim tab the same way you build the ailerons, two very small spars with the hinge. These pictures show the dimensions of the trim tab actuated by a MAC servo.

Unlike many KR’s with aft CG, my KR flys great because it is forward CG. Again, I listened to other KR pilots and found the CG range was too optimistic. It was stated, DON”T FLY IN THE AFT 2 INCHES!!!! So Dan Diehl, told me that with the original motor mount, which I had, I should move the engine forward 2 inches. Given the new mount I figured it would be easier to simply photograph the distance the engine case is from the firewall. These two pictures do that.

I hope you find the information on this page to be helpful. If you have specific questions about a part of my plane, please e-mail me and I'll update this page with the answer.
