KR> Preparing for KR2S build - again
I would also go with longer then the Diehl 24 inch gear legs. Mine are 30 inch ( https://dl.dropboxusercontent.com/u/32133949/002.jpg ) but 28 inch would probably work well on a stock KR2S. You'll have to make your own as the 30 inch legs are probably not available for purchase. Jeff Scott and I have the only two sets that Dan Diehl ever sold. I'd also go with my Aviation Products lightweight single fork tailwheel assembly modified to accept the 6 inch Matco wheel and pneumatic tire. The noise level over a solid wheel is night and day.

Nothing added forward of the spar and I have standard KR2 tail surfaces. Starting over I'd go with the standard KR2S length and the 2S increased tail surfaces, and the two inches forward of the spar. Also the wider fuselage at the shoulders. That would be very much like the 2S that Langford built and I think he would agree it was a great flyer. As for a header tank, I went wing tanks only in the out wing sections. That's a personal call. I read a crash report years ago about a KR1 that had a hard landing, the firewall broke away and the ruptured tank dumped it's contents on the pilot. Why it never caught fire is a mystery. My two major concerns when building were fire and roll over. I put all my fuel in the outer wings and built a fixed windshield with windshield and turtle deck bow with gullwing door and breakaway section on the passenger side. https://dl.dropboxusercontent.com/u/32133949/100_5561.JPG Your concerns and comfort level may be different so build to suit yourself.

I have been hanging upside down by the seatbelt in a KR with the header tank on fire. All the fuel in the wings is wise advice.

Hey Gary, This going to be advise from someone that can say I am doing it this way on their second build which I am in the middle of. In addition to the things mentioned below or to clarify. I will make my comments as per the list you have provided below. Number one and number two I have completed Number three - this term has been used in a number of different ways that has always bothered me as for its clarity. I am flying my first KR2S and it is longer than a KR2 and mine is 1 1/2" longer than the KR2S plans. It flys and weight and balance is great even with burning 12 gals out of a header tank. So are they telling you another bay longer than a KR2 or KR2S. There are weight and balance implications to getting the weight too far back also. I think that Larry F has an extra bay above the 2s but I also think he may have added forward of the main spar also I am one of the people that think the KR2S elevator and and horizontal stab are more than adequate and perform well on my plane, havin said that the new one has them wider for both and with the airfoil as opposed to the stock slab design. The angle of incidence and the relationship to the wing incidence is of far greater importance here. Number ?four.. increase the vertical height is yes good but I feel it would be more accurate to say how much should the area of the surfaces be increased. I think and will have to double check but but I think that i increased the vertical stab and rudder by 20% over the 2s design. I absolutely need more control for some of the crosswind landings and takeoff's I have gotten away with. Number five - use the larger airfoil- I am Number six and seven ... yes .. I am Number eight.. I find that i can not give up the safety factor of having a header tank that can gravity feed my engine. The argument of fuel in your lap is emotional at best, I do not remember any instance of accidents that the header fuel tank was a factor (i will likely get corrected here) I currently have built and plan to use wing tanks in the outer wings at 10 gal each and am building the header tank that will be the reserve (always) of about 7 to 8 gals. I do not have the fuel pump and line configuration completely figured out yet but am very close. ?? ?Suggestions Keep it light... light LIGHT! clean off the extra glue -clean up epoxy runs- make sure foam is sanded correctly because everything after the glass is just weight in the form of filler- resist adding additional layers of cloth except the deck cloth which goes a very long ways towards the ultimate finish. There does not need to be beefing up of areas it is already stronger than I have been able to break. I am not installing motors for belly board or trim opting to save that addition of weight for auto pilot servos (which I have installed currently and will not go without again either). I am on the fence about instruments at this point about how much glass is to much but there is certainly a weight savings to be had right in the panel of first guess is the upper side of 5 lbs. Your results will certainly be different, but hope it helps some.

I feel like I am almost starting over with the KR2S. With the end of my caregiving responsibilities, I now have some time to get into the build.

Dang Mark! That's a great airport. Our airport is much more challenging, take a look: http://www.wilgroveairport.net/contact.htm 2700' of usable runway. Hi-tension power lines on the south end and 60'+ trees on the sides and north end. This is where I learned to fly. -- Wayne DeLisle Sr.

I knew this airport looked familiar, I flew right over the top of it enroute from Moontown to KSET in St. Louis last July. Flew a Rans S12 back for the new owner. Beautiful strip!!

My GPS had me right on top of Mark's field but all I seen was brown grass dirt.??
