I have been thinking about what to do for my Pular Jabiru cowling for months and seeing you work is quite inspirational. I guess I need to quit thinking aboit it and start building some prototypes.... I'm try to figure out how the NACA will be installed that you mentioned to help the exhaust ?? Mind telling me more? Thanks, Ned "since I plan to build in a NACA duct into foam glued and glassed to the bottom of the fuselage for exhaust and cooling air to exit (I got this idea from Troy Petteway's latest incarnation).

What I mean is that the wide deep part of the duct is the exit under the cowling, just below the firewall, and it narrows to a taper (converges) as it goes aft, while getting shallower, until the air is smoothed into the slipstream in the same direction and at something close to the speed of the air that's moving over the rest of the plane...

A better solution is to do it the way Steve Wittman did on his Tailwinds. He picked up high pressure at the base of the windshield and low pressure from behind a gear leg (both take some experimentation to find) then used one to blow and the other to suck on the same instrument.

If you want to save money & time go to work at MacDonalds you will be able to buy a production aircraft in less time. Building a plans built a/c means every part is a prototype and usually has to be built 2 or three times. But think of the learning experience and the friends you meet. Just got my sport aviation. Its tough sledding up here in the summer so the mail is slow. Great article Mark. A very unique contribution to sport aviation.

There are plenty of areas where the KR can be modified to improve it (in general) or to simply make it unique from others. The amount of time one wants to spend doing this is entirely up to the individual. I personally did not want a "clone plane" and chose to build from plans, not a kit. Personal desire. I am at the 650-hour point myself and have the following left to do: -Mount engine -Instrument panel -Wiring -Close and finish outer wings -Seal and paint I have modified the following: -Wings (new airfoil, length and changed the method of fiberglassing the foam) -Tail (extended H-stab and modified Rudder and new airfoil) -Fuselage (extended width aft 10" to reduce drag) -Engine (Corvair) -Fuel cells (aluminium, in the outer wings) -Seats (fiberglass of my own design) -Fuselage tank removed and storage compartment inserted While my airplane will not win any awards as the slickest KR-based aircraft around, my intent is to have a safe, reliable aircraft. I am convinced that I can do that in around 1,000 hours. I have received compliments on my wood work, so I cannot be all that hasty in my building, but it is not a race, either. My costs for a VFR++ aircraft will work out to about $22,000. All that for a plane that will likely go 180+ MPH on 5.6 GPH. The beauty of this aircraft over others is that you can take as much time building it and making it a reflection of yourself as you desire... and when you are done there will be none like it!

He rates the EJ 2.2 at 100 hp at that speed .I should mention that Don Parham is an engineer , and is of course quite comfortable with the electronics involved . Now before you start laughing at that 60 hp figure , let me tell you that Reg Clarke of AIR RYDER originally used an EA - 81 without a turbo ! Wayne ; how about rephrasing the issue yet again ? The displacement of the ( 2.2 L ) engine is of course fixed : I am doing nothing if I am not turning that crankshaft .If I can turn the crank fast enough , I can get the result I want .What are the obstacles ? Well , the use of electronics would get me ahead at least 15 hp , but I'm seriously considering carbs ( kiss ) .The real trick is to find the optimum prop After cooling , props seem to be the biggest issue ...the guys on airsoob seem to come at the problem from every which way , getting quite varied results .I'd really like to hear from someone much further ahead - especially with the 2.2 L .----- Original Message ----- From: Wayne McMullen To: Richard Parker ; Sent: Tuesday, July 17, 2001 10:31 PM Subject: Re: KR> KR and soob engines > Let me rephrase the question.

Remember that Labor dollars are all relative. If you take out the reason behind doing something ( the fun factor and sense of accomplishment) and try to equate it to what our perceived value is we would never do anything ourself. Example - Mowing the yard : Straight labor costs (what I would see in my pay) $30.00 per hour (not counting mower, gas, oil and sweat) , Pay the kid down the street $20.00 (his dad's mower, gas ,oil) Why do I do it? I enjoy it. I have friends that are MD's and they mow their own yard (their hourly rate is substantially higher) for the same reason. I think that the reason people like this aircraft so much is that it is designed so the "average" handyman can build and fly it using his "average " skills and abilities in a reasonable timespan. From what I have seen some people have gone one step further to refine the design by adding improvements. I applaud them for their innovation. They are the ones that help the rest of us think. There is no price that can be put on the satisfaction in building something and making friends with a common interest. Plus if we had the money that we perceive our labor has cost we could go buy a someone else's RV or even a Lancair. Where would the satisfaction be??? Bottom line is this. Continue building. If you get to something that is beyond your capabilities/budget then explore your options. I think that you can still get this airplane in the air at a cost that many of us can afford. Even as Mark L. has said about what his labor costs projections are, I bet he wouldn't trade it for anything. Expecially after a hard day at the office when all you do is hit your head against the wall. You can then go home and do something, anything (even sanding) and get the feeling of satisfaction that the day wasn't a total loss. Another way to say it is "Keep the dream alive". Norm F.

Then run an aluminum tube down the firewall to a place away from your exhaust out under the bottom of the plane into the slipstream and bend it forward. This will keep it out of site and any fuel that may get out, will come out the bottom. It also puts positive pressure on the tank. I would think that an unvented tank would have a problem letting fuel out as it could not get any air to replace it. I would also think that you don't want those fumes building up pressure in your tank while it is sitting it that hot hanger. I put this vent on the Little Beast. It was easy because it has an aluminum fuel tank and I could run the vent directly into the top of the tank at the front, under the forward deck. This new KR has a glass tank, so I had to go directly into it just under the top edge in the center front. This makes for a clean installation as you don't see that vent sticking up on top of the deck.

I did initially install a nipple in the intake of 616TJ and it spun an artificial horizon and DG quite nicely. The only time you won't have vac. is at a high power setting. We have a secondary vac. installed on the Bonanza that is STC'd and is exactly the same thing. The only thing you need is a pressure regulator between the intake and your instruments so as not to exceed vac. pressures of the instruments.
