KR> Young Eagles Rally
What to do when your EAA Chapter 478 has a Young Eagles Rally, your KR-2 is still serving a Phase 1, 40-hour sentence, and the local FBO, that you normally rent a C-150, just went out of business? Take off the upper cowl and do a pre-flight show & tell briefing for the 155 kids signed up to fly that morning at the Rally. I did 4 to 8 kids at a time so that the pilots did not need to take the ten minutes or so to do the brief for each flight. That really helped speed up air operations. Plus the kids were able to actually see an aircraft engine. I only did the briefing 27 times. We managed to fly 132 Young Eagles using 14 aircraft before thunder storms shut us down. The other 23 got first debs for our First Responders Rally for August. https://s3.amazonaws.com/expercraft/sidwood/1202926268557648611dfb1.jpg Sid Wood Tri-gear KR-2 N6242 Mechanicsville, MD, USA

KR> rudder stops
"Hey Guys, Looks like I'll be doing Rudder stops as an afterthought. What's the best place and method for this ?" I don't often contribute but I think this time it is important. My take on this is; I am installing stops at both ends. The reason: I hear it is accepted good practice to stop the control surface, and the force in the control cable is exactally the same at any point in the system. does the force originate from your foot or the airodynamic force on the rudder? Which is the applied force and which is the reaction makes no difference to the components. For the usual KR style rudder peddle assembly, if the horn is stopped and the peddle still has travel there will be a high amount of torque applied to the peddle assembly. That is how mine failed. The pilot applied more right rudder force that was effectivly needed (not hard to imagine in a stressful situation). The horn stopped but the peddle continued for another half inch or so and the miter joint on the peddle assembly snapped. The resulting ground loop provided an opportunity to redesign the landing gear, I never did like that design. nothing was bent on the peddle assembly so I simply welded it back together and added a wrap around gusset with the welds in shear increasing the torsion stength many time over but now the added torsional strength is mostly redundent because the peddle assembly will not be loaded in torsion any more than would be applied by normal aerodynamic rudder load (or is that foot force?). That's my story and I'm stickin to it. Pete Gauthier KR Builder Woodburn, OR
KR> rudder stops
The highest loads you'll ever put on your rudder cables and rudder horn are when you are braking if you have toe brakes. The Tony Bingelis books advise using stops at the control surfaces to prevent overload and damage at the control surface hinges when parked with a tailwind, should you happen to do a tail slide, or for any other reason that your controls might be loaded or pushed from behind. The KR series of aircraft are a bit unique in that the builders manual does not recommend the use of control stops. If I remember correctly, it doesn't mention them. I don't know how that could happen with such a high quality modern builders manual.

There was no 2013 or 2014 Big Muddy race. A couple of Midget Mustangs only beat me by about 15 mph. I was pleasantly surprised. My IFLY 720 did a great job of keeping me on course. I owe at least a portion of my success to it. It had a 5 mile ring around the KR with an extended flight track line and a constant update on how many degrees to turn left or right to stay on course. I simply maneuvered to keep my extended track line superimposed on the course line. Larry Flesner

> "There were no SX-300 in the Big Muddy race but there were some fast airplanes like F-1 Rockets and Glassairs." Yep, looks like the race results I was looking at are from 2012. Race results since then seem to be secret. When I Googled Big Muddy Race Results it came up with the 2012 results and because I saw your name there I didn't even look up top and notice it said 2012 instead of 2015. The current race results and those since 2012 are beyond my Google-fu to find. 170 MPH on a sustained run with only 100 HP is extremely impressive Larry.

Gary, Your way of building the boat sounded pretty good. One thing that I would do different is. ?I would not glue the top down. You want to be able to disassemble it when you're done. Or cut it down smaller when your needs change.?

It is Burt Rutan's basic fiberglass sandwich construction instructions and was my manual on that subject together with the build manual. Basically, I built a frame of 2x4s with 1/2" plywood. I did it by using 8' length 2x4s and cut a 4x8 1/2" piece of plywood in half for top and bottom. I put a cross member 2x4 every 2 ft and glued and screwed the whole thing together. I sanded one side and covered is with 2' brown wrapping paper on which I drew the side frame. The platform allows you to screw on blocks to hold the frame while gluing. Use wax paper under the glue joints to be able to get the side frame off the platform. I divided the sides in half and made two front halves and then two back. I tapered the longerons at the joint end per FAR 43.13 to splice the front and back together. To join the halves I drew the center section on the paper to keep everything straight. I glued doublers top and bottom for the splice and extended the doubler on the top called out by the drawing past the joint. This way I didn't have to have a 12' or 14' table and if you order the cap strip it can be shipped a lot easier and is cheaper and I think the joints give a little more strength for when you bend the whole thing for the boat.

KR> rudder stops
That looks like the missing piece of info that I was wondering. I suppose nothing stops one from having both, and I wonder if that would be prudent. I could relate to the comments about over stressing the cable and pulleys and in a adrenaline situation we may not be self-aware and push the foot too hard. So it looks like we have a reason for something to protect the flight surface from banging over too far, and also the control cable and related from being stressed.
