KR> gear legs
Recent discussion on gear legs using Yankee gear. I measured my Diehl legs (30 inches long) to which I added additional glass and they measure 1 inch thick. I also added 1 inch of foam to the front and rear edge to run brake line and to shape to streamline. My empty weight is 765 pounds and have on occasion flown to 1320 pounds. This seems to be the ideal length and thickness. My KR is a 24 inch stretch over the standard KR and this dimension gives a nice 3 point attitude on the ground. My wheels are set for zero toe-in / toe-out and the tires show little if any edge wear and ground handling is superb. On a KR2S you may want to go with a 28 inch leg to account for the slightly shorter fuselage. Lower leg fittings are easy to make with a 2X6 inch X 1/4 inch piece of 4130. Make a saw cut at the 3 inch mark about 3/4 of the way through the metal. Bend at the cut to a 45 degree angle, weld and dress the cut, and weld a gusset on the inside. http://myplace.frontier.com/~flesner/21.jpg A single washer on the top two axle bolts between the axle and fitting should give you the correct camber. Set toe-in / toe-out by drilling one hole in the gear leg to attach the bracket, snug it down, set toe-in / toe-out, and drill remaining holes. I think I'd suggest using the Diehl profile on cutting the Yankee legs as I believe they are made of the same material. I'm using the Cleveland 500X5 wheels and brakes and the RV wheel pants cover the entire assemble and work great. http://krgathering.com/picture_library/Gathering%202011/N211LF/RRL_2710.jpg As alwaysYRMV..

KR> Chino trip
Hey Guys, I had planned to write up a bit of a story and include a few pictures of the trip of a life time for me but I had a computer melt down at the very moment that I was down loading the picture card and I lost over 300 pictures from the time we left LosAlmos until I got home. I'm very unhappy with this to say the least.

KR> Nose wheel weight
Not sure I've ever heard of an "ideal" weight, but mine worked out to be 200 lbs on the nose gear with 200 pounds on each of the main gears.

KR> Nose wheel weight
Thanks, Ernist was answering a question about axle placement back in 1976. I don't think this was brought up with Sid's plane. It was all about cg.

Paul Visk Belleville Il 618 + Given identical gear setup, the weight will vary from aircraft to aircraft depending on how it is built (loaded) and where the empty CG falls. Identical gear setups with the CG at the same moment arm should have very similar weights given identical aircraft empty weights. Any change in gear location or aircraft empty weight will cause the weights to change also. My gear legs, being slightly longer and placing the main wheel contact slightly forward, will cause my tail weight to be slightly heavier. Remember, the CRITICAL factor is the flight C.G., not weight on the ground. A slightly lighter or heavier weight on the nose or tail will effect takeoff and landing handling, not flight performance. Given identical gear locations, a large variance in weight on aircraft with the same empty weighs probably indicates a CG problem. An RV 10 I helped on weighted out just 4 pounds different than the factory example. The nose wheel weight came out several pounds (15 pounds as I recall) lighter than factory indicating the empty CG slightly aft of factory. Well within range and not a bad thing on an RV10 which is considered to be a bit of a nose heavy airplane. Those in the know recommend flying it with 50 pounds in the baggage area. Too many variables to say any weight is ideal. It is what it is as long as the C.G. is located properly. Larry Flesner
KR> Proseal-fuel tank rivets
How much proseal do i need for sealing the rivets? My fuel tanks are 10" wide x 48# long and tapered . I see Aircraft spruce sells 6 oz tubes . Maybe two tubes per wing tank? Joe Cruz cruzj12 at frontiernet.net KR1.5 N3151K KR2S builder

Would anyone be willing to send me a scan of the KR2S supplement? ? After more than 2 months of waiting for the plans and a couple notes from Nvaero saying my order was going to sent I came to the conclusion that Nvaero is for whatever reason not interested in doing business with me. I requested they cancel my order and refund the price paid. Guess I'll find something else to build. I would just like to have a glimpse at what could have been. Thanks Gary Wold
KR> Proseal-fuel tank rivets
You can get the brand that all the RVs use from Vans Aircraft for less and it works well. I think you should get a quart. I built wing tanks for my KR2 using it and it worked perfectly. Do not skimp on the application. Be sure you have ample amount on all the seams and rivets. If you cannot find it, let me know and I will find it for you as I need to order some as well.

Paul Visk wrote: >>I just read in issue 15 of the news letter that the ideal static weight for >>the tail wheel is 5 lbs. Does anyone know what the ideal weight for the nose >>wheel is? << I'm no help with nosewheel weight, but five pounds is probably a pretty good number for a KR2 taildragger, and that's exactly what N891JF has. The CG on that plane is on the forward side with pilot only, especially me. If I raise the tail past "longeron horizontal" with a full fuel tank, it'll end up on it's nose! N56ML (a KR2S) has about 25 pounds on the tailwheel, and you couldn't ask for a nicer flying airplane, but that plane is longer, fuel is located right on the CG, and it has much larger tail feathers. If KR2S builders discover you have more than about 40 pounds on an empty KR2S taildragger (or less if you're a heavy guy), read my harrowing "aft CG" account at http://www.n56ml.com/wb/index.html, and consider redoing your weight and balance... -- Mark Langford ML at N56ML.com http://www.n56ml.com

KR> KR2S supplement
Buy someone's project; if you pay attention, you will save build time, get something well built, and get a full set of plans for less than you would spend for the materials. I have a KR2S and KR2 project (not for sale) and each came with a full set of plans, builders logs, etc. We all start with the idea that a KR is a hot rod, but basically it is an aviation equivalent to a motorcycle; small, fast, and you will need to pay attention. I haven't finished building the KR, but mine will weigh a little less than my HD Dyna Super Glide Custom and the KR will probably be a little faster. My cost will probably be about the same to build the plane as the bike cost. Mark W.

KR> Tri-gear main wheel location
I made my gear legs 1/4-inch wider than the stock Diehl gear legs and 1-inch longer than the tail dragger version. My theory is the extra length is needed to compensate for the extra angle to get the needed 3-inch set back and to get a more level stance on the ground. The 1/4-inch extra width will add about 8% additional stiffness to compensate for the extra length. Some extra twisting comes into play due to the boomerang shape. That extra torque would be about 100 pound-feet at max gross. That seems nominal to me. I don't know the math to actually calculate the spring constant and don't have the lab facilities to empirically measure the various combinations of gear leg shapes. My approach is to duplicate the performance of the stock gear legs and adjust for my particular KR-2 configuration for 800 pound empty weight and 1250 pounds max gross. Sid Wood Tri-gear KR-2 N6242 Mechanicsville, MD, USA I got the same legs, but thinking of leaving the same thickness but using the full length of the Grumman blanks for prop clearance on my tail wheel. Just waiting on some cast brackets from Steve so I can finished them off. Do think the Grumman leg thickness would be too much? Mark L commented on leaving them as is as they are longer, Any finished and flying these legs care to comment?? Phil Matheson. Australia -- Update on moving the main wheels on my KR-2: Removed the main gear fiberglass struts. These are supposed to be used for a tail dragger version. Obtained Scotch ply Grumman Cougar blanks from Fletch Air. ___ I've been thinking on this as well. I suppose one could leave them the full inch thick but make them narrower (i.e. not as wide) if they were too stiff. Leaving them longer (which I also plan to do) will offset some of the stiffness, and additional stiffness will probably be a good thing given the higher gross weight KRs seem to be built to these days (mine will be 600kg/1320 lbs). I don't know enough about the engineering of springs to make an informed decision here, so the experience of others will be welcome. Cheers, Tony - I have installed the Grumman legs on my KR2-S. I kept them the original length and thickness but trimmed them down in width. Minor deflection as the plane sets now. Fuselage, tail, controls and motor mount (weighs 198 lbs). I have also used the fiberglass leg for the front gear. With me in the aircraft (250) gross so far at 448 lbs the gear deflect about 5/8". I expect a total of 1" deflection as engine, wings, fit out and fuel are added and dispersed across the 3 legs. I can send more detail and measurements if your interested. Dan Prichard > >I have installed the Grumman legs on my KR2-S. I kept them the original length and thickness but trimmed them down in width. That is exactly how I would do it. Our planes are heavier these days anyway, so some extra thickness is not a bad thing. Mark Langford ML at N56ML.com http://www.n56ml.com *
