He was running the FBO in Grove Field/Camas ( 1W1 ). To help his wife out of debt, we are currently selling his tools, supplies and his KR2 project. I would appreciate your help to find out whatīs it worth. I have set up a website for this purpose with all the pictures I could take. Please check at http://scott.jet24.de N50WM is still registered to the previous owner, and we are currently missing all paperwork. Due to the situation, it might be impossible to find the logbooks etc. The body is sanded for repaint. From what we heard, it was sitting some time on the ramp in Tennessee, including rainy days. None of us has the experience to determine if the body is airworthy or not. The engine is a converted VW, but we canīt figure out the converting company. I have personally talked to Scott, and he was very happy about the KR2, because the engine was running so good. Since he was a very professional AMP and IA, I believe that. The prop says Marfa Hegy, TX . Thanks for helping me to find a fair price for Scotts wife and children.

" Hey there, Not a KR pilot yet, Awaiting delivery of some plans and already working on some mod's and currently designing a separate craft of my own ;) You can probably go lower with little ill effects if your gross weight is significantly lower than the tyres rated load. You can judge this by watching the spread of the tread as the tyre inflates with a full load. For flat treaded tyres, watch for separation of the edges of the tread from the ashphalt, go back a little past the point where they touch again and that should be it. For grooved, rounded profile tyres, do something similar, but use the inside edge of the outer grooves as your reference point If you are going to be flying to/from softer ground, like a wet field or sand then you can reduce the pressure by up to 1/2 that for better traction. but this can quickly lead to tyre damage if used on a paved surface for extended periods.

PETER WASTNEY >ENGINEERING LTD ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ I think the FAA in this country likes to see 9 inches. That would be with the tail up in a taildragger. Remember, your gear legs will flex on landing and could reduce that clearance by several inches. Also, you don't want the tip of you prop running in the grass on a grass strip. You may have to consider some method of increasing your gear leg length.

A hard landing and gear compression can use up this clearance in a hurry. You should also being always trying to land on the mains first in tri-gear, and either 3 point or wheel land you choice on conventional. Greater clearance is needed for the conventional due to the possibility of having a tail high wheel landing, and hitting hard. The longer the gear legs, the more chance of greater compression/more there to flex, so also keep that in mind. I believe the Grove gear is taller. The primary purpose I have read about the prop reduction units are not to be able to run larger props, but to take the loads off the engine crankshaft, and isolate them to bearings designed more for that load. Secondarily you also slow prop, allowing it to operate more in its range of efficiency, and you multiply the TORQUE (not horsepower) of the engine due to the gained mechanical advantage (similar to a car's drive axle ring & pinion gears).

The plans don't really say, but a spruce list I have from Rand seems to indicate that the pieces were intended to go side by side, as in the glue joint going vertical with the spar in the normal orientation. That is also the way that the spars were made in the three KRs I have had. I know that you thought about this before you did it and probably have some good reasoning on deciding to do it this way. Could you tell me what it was. Before anyone gets the idea that I am saying one way is right or wrong, that is not what I meant at all. I have seen spars in production planes laminated in either direction. For tall spar caps you normally see a vertical glue line and for bent laminated spars you have no choice to go horizontal. The A.C. 43.13 states that laminated spars can be used in place of solid spars without a reference to direction and a laminated spar should be stronger than solid wood no matter what direction the glue lines are in. I am just curious on this. The only thing I wouldn't do is build a spar with a horizontal glue line right where a bolt hole is going for the wing attach fitting.

Davis (U.S. Navy and Boeing Program Managers) officially loaded the aft carry-through bulkhead onto the X-45C Assembly Jig, formally starting production for the first aircraft. The ceremony was attended by DOD dignitaries, Boeing executives, supplier representatives and of course the X-45 team. The ceremony was also simulcast to Boeing sites in Mesa, AZ., Tulsa, OK. and Seattle, WA. Team members were asked to autograph a X-45C Production Banner which will hang on the wall over the production floor. Boeing also supplied team members with lunch and special edition coffee cups to commemorate the occasion. Thus far the X-45C program is On Schedule, On Budget, and 165 lbs under allocated weight.

In that case you would have two independent strong spars next to each other. Of course, if you have leave crappy glue joint in your spars you should give up right there and stick to model planes.

The pilot was up and walking around when the emergency vehicles arrived onsite. He *was* taken to the hospital for a check but his name hasn't been released yet as far as I know. The tail number is: N250KB and the accident is, of course, under investigation. He had just taken off and landed about a half-mile from the departure end of the airport runway. I took some pictures this afternoon and there wasn't much evidence of a hard impact in the ground but the plane pretty much disintigrated except for the tail feathers.

That was Don Betchan's nice "motorcycle" retractable gear KR, which became a standard showing at the KR Gatherings. That sure was a nice plane, with a lot of ingenious modifications, and we'll all miss it...

The ultimate reference book on the subject is ANC-18, Design of Wooden Aircraft. It states that the direction of lamination makes no difference in the spar strength. It is only a matter of convenience and availability. Regions of the spar which have highly loaded bolted connections must have reinforcement in the form of cross banded high density plywood to help prevent splitting. Bolts should not go through a glue line.

Are up using Tri gear or tail dragger I have Diehl gear, and the new nose leg is long and my need shorting if I do not lengthen the main gear. I have around 10" clearance ?? but not sure on Prop as yet I will be using the RG2000 from VW engines Australia. http://www.vw-engines.com/ This has a Geared reduction, and can run up to a foot prop.( 200ft lbs torque) Picture of the RG2000, on my unfinished web listed below.

I needed to buy a 12' countertop anyway for my office so I was going to level it with a precision machinist's level to be sure it was perfectly flat and level. I would cover it with bagging film before I started. I was going to scarf the plywood pieces and let them dry before I started the rest of the spars. Next I was going to lay out lines on where all the pieces went and dry fit everything with the web laying on the countertop. Then I was going to spread T88 on one spar cap and the web and set it on, followed by the vertical spacers, then the other spar cap. Then I was going to put a bunch of heavy weights on the spar caps. Next I was going to put a bar clamp at each vertical spacer location to clamp the spar caps to the verticals. Then I will use a brush to spread all the excess epoxy around the inside to seal the inner sections of everything then put a bunch of weights on the caps and verticals to be sure they are pressed tight against the plywood. When the whole thing dries I will put on the top plywood web. Does anyone see anything wrong with this sequence? Am I going to wind up with the T88 drying before I get everything done?

And well thought out. You should have sufficient time with the T-88 to accomplish what you propose. Just remember that T-88 is as slick as owl poop until it starts to set and things can move around if you are not careful.
