KR> Repair to a Longeron
Tough break Allen, I haven't bent mine yet. So, my heart goes out to you in this. If your'e going to swap ends, that means taking apart all your glued up joints, (that sounds horrible). The repair should be stronger than the original wood. I would probably just try and repair the break, and then bend it slowly over several days. What kind of plane is this on? Russ
KR> Plans question
I'm at the same place you are Nick. I took it to leave off the last verticle before the long piece that goes to the top of the vertical stabilizer. I could be wrong; I'll read more about it this weekend. I finished the second side this last weekend, Yay! I'm tired of the gussets! Russ
KR> forming boat, glueing on plywood
Hi Everyone, I'm kicking around whether to glue the plywood on before or after forming the boat? The plans recommend before. I guess I'm afraid of breaking a longeron in the bending process. Russ http://home.bendbroadband.com/russkr2s

KR> Plans question
Hi Nick, I'm at the same place your at; and I've been scratching my head abit also. I've left the verticle at N out, and left myself about 8" extra on the length of the longerons, (since I'm extending the length aft 6"). I wanted a little extra to play with. I noted on Ricky Farleys webpage he gave some good advice on ,"What not to". He chopped of his longerons with the 7 degree angle at 0, not realizing it is actually a compound angle due to the angle of the sides meeting at 0. I've been kicking around the idea of skining only the front half of the fuselage on both sides, (as Ricky did, you can see it on his web page). I think I'll cut my scarf joints in the plywood and T-88 them up to J, (which is the verticle under my scarf joints). The fuselage from J back should be fairly flat enableing, (hopefully) a fairly easy glue of the plywood. I'm thinking having the back of the fuselage open is going to facilitate the set up of the "Webs" for the horizontal & verticle stabilizers. The plywood on the front and rear of the verticles at N sandwiches the front spar of the horizontal stabilizer. If one were to glue the verticles in while the sides are flat on the bench the two verticles, (one on each side) would be square with the side, but not with each other. These two verticles must be parallel with each other in order for the plywood, that goes on each side of them at N, to fit flush against the verticles and sandwich the spar of the H.S.. Until you get your sides clamped or glued into position, it's going to be pretty much impossible to guess what angle the verticles at N need to be. They'll be actually twisted on their axis to be parallel with each other. Also to get the front spar of the H.S. square with the fuselage it's going to be easier to actually have it sitting in the slot formed by the "Web" (the plywood sandwich created with the plywood on both sides of the verticles at N). a fraction of an inch off at the fuselage is going to be exagerated at the tip of the H.S. spar. So, to try and sum all this up. One won't know what angle to set the verticles, or to cut the rear of the longerons until you have the sides clamped together. Depending on how wide you make your fuselage the angle of the sides to each other will change. I'm sure one could figure it out with geometry, but hey I'm just a KR builder. This is probably as clear as mud, but my intent is to help Russ

KR> lengthening main spars
Hi everyone, I'm widening the fuselage to 40". Which got me to thinking, I should also lenthen the main spars to compensate for the for the loss in wing area. Which got me to thinking about going even wider, say an extra 12" on each side. Since I'm going with a Trigear setup, the Diehl main gear bolts behind the front main spar, which loses me fuel tank area. The wider stub wing span would give me more tank area. I'd also have more flap area in the stub wing. What's do you think about longer main spars? I'll be using the AS5048/45 airfoil which has a stronger spar. Thanks for your input. Russ Kendall

KR> Waiting for the plans...
Hi Nick, I'm only slightly ahead of you. I recieved the plans a couple of weeks ago. I already had some longeron material I was going to use for a VP project, but figured if I was going to go to the trouble of building something, I might as well build something big enough for my wife and I both to fit in. I bought 4 sheets 4'x8' of 3/32, to go with mahogany or birch is a personal decision, and a 4x4 sheet of 1/4" birch for the firewall. The canopy from Todds is somewhere between here and Florida, the landing gear is also on the way from Diehls. I bought 2 quarts of T-88 thinking that would hold me for awhile. I'm anxious to get the boat built and on the gear. I had a printing company print out the templates for the A5048/45 airfoil. I thought they were kind of spendy at $120 for the print. I got the 4' by 16' table up day before yesterday. I did all this pretty much without looking at the plans. To go with Wicks or A.S.S. co is a personal decision. I'm not much of a kit kind of guys, so I prefer to buy the stuff as I need it. I'm not in a big hurry for the WAFs yet, as just getting the boat built is my first priority. I wish you the best of luck, and a good build.

KR> Fuselage length
Hi Randy, If you're making decisions based on the note I wrote, you might want to listen to what these guys are saying. I'm just throwing ideas out there, trying to get information. Changing the length significantly has its ramifications; one being the plane may be very difficult to balance if not impossible. Whatever I decide to do, I take on the responsibility of, it might not work. I'm just gambling on leg room because I have to. I've grown up with clothes that don't fit, cars that don't fit, and now planes that don't fit. Being tall has it's short commings. I'll probably go with the 2", but it might not work. I'm still trying to decide on what to do with the back of the fuselage.

KR> Fuselage spar slots
Hi everyone. I've got a question on the spar slots in the fuselage. How close a fit should they be to the spar? If it's a tight fit then changing the incidence changes the angle of the spars to each other. If it's a looser fit then the wing can be tipped forward without changing the angle of the spars to each other. It seems to me one would want enough play between the slot in the fuselage and the spars to enable tilting the wing to set the incidence? Russ Kendall

KR> Balance-lenthening fuselage
Hi everyone, I've been reading everything I can find in the archive in regards to moving the firewall forward to give me more leg room, (I'm 6'3"). From what I gather, moving the firewall forward is risky. I'll be going with Diehl trigear, corvair, wing tanks, my weight is 200 lbs. frequently fly with passenger. I read where Mark Jones moved his firewall forward 2". I'm considering extending the rear of the fuselage back another 14" more than what the KS plans call for, as Mark L. suggests. How do you think this would affect a KR2S in trigear configuration? Or, should I just go with the enlarged horizontal stab., which I'm thinking would weigh more? I realize every plane is different, but I'd really appreciate your thoughts. Thanks Russ Kendall
KR> Balance-lengthening fuselage
Thanks Mark, I really appreciate your input! I guess I'm at that point where I'm making critical decisions on design, and not being an aeronautical engineer I'm floundering abit. It's 5:00am and my wife just came in to the computer room to find me sitting on the floor leaning back on a piece of plywood with blocks under my knees, (simulating my front spar) a cup of coffee in one hand, and my tape measure in the other. She just smiled and gave me hug, (I'm a lucky guy to have such an understanding wife). I guess there's no real way of knowing how the balance is going to turn out until it's done. All I can do is try and be cognisant that it's going to have to balance out in the end. Take what info I can glean from others who've gone there done that, and hope for the best. I've decided to go with the 2", as you've done Mark, adding an inch from A to B and B to C. I think I'll go with an extra 14" bay in the tail, and cross my fingers. Mark L. wrote, he thought one might go with the stock H.S. with the increased moment of an extended rear fuselage. However, I'm contemplating going with both the increased length and the larger H.S.; not only for the increase pitch stability, but the larger H.S. would throw a little more weight back there. I'm hoping with an internally counterweighted elevator, and the extended rear fuselage, it will help offset the 2" firewall change. Here's hoping. Having long legs does present it's problems.
