I found that I was not getting a complete squirt when the pumps had been left for awhile. So I began a habit of having 2 epoxy cups handy, one to squirt just enough epoxy and hardener to prime the pumps fully, then dispense the amount I wanted for the job.

I have all the info and would appreciate if you would circulate the info as widely as you are able. I would like to sell my KR2 because I have another in my garage and a hanger in a state of partial completion and can use the funds. The plane is a standard KR2, on trike gear and using a Subaru engine and belt reduction drive. It has undergone a full re-build, with many new parts, all ignition system replaced, new tank, tires and tubes, prop, radio and GPS. I'm in New Brunswick, at 506-856-7977 or available here. I'm asking $18000 CDN. Best bet is to come here to look it over, and go for a ride if you are able. Then load it on a trailer and take it home before the snow flies. PS it was -5 here this morning. Hope you enjoy the pictures and will let me know that you received them.

Over here we are very limited to materials that we can use for things like this so most of us take a trip to our local leaf spring manufacturer and purchase enough stock to bend up two legs. At 14mm thick and around 80mm wide they tend to weigh a fair amount! You could trade a lot of 1.5"x0.125 wall 4130 tube for the same weight!

I am now well and truly confused! It was my understanding that you used a regular length drill for alignment purposes inserted through the jig from the rear and held there with finger pressure. The long bit is then used with the drilling machine through the jig from the front. The long bit will go through the spar and then push the regular bit out the rear and "PRESTO". >From one or two of the replies it seems that drilling from both sides >with a regular bit is recommended meeting up somewhere in the middle of the spar. Either way the drilling jig is a must, that much I do know. So which way is correct, drilling from both sides or from one side only?? Also guys, don't forget I live in a metric world here and I have tried all the machine tool suppliers around here believe me. I believe that drilling the fitting holes then removing them from one side before installing the spar into the fuz is by far the easiest, most accurate and quickest way of getting it aligned spot on.

Dan Walker is looking for a prop for his VW engine. The prop bank has one that Dan can try out and if he likes the prop then he can purchase the prop form the Prop Bank. Dan, if you are interested in trying a prop from the PROP BANK, please contact me directly at flykr2s@wi.rr.com EVERYONE PLEASE READ THIS: THE PROP BANK As most of you know and some don't, there is a propeller fund in the making. This fund will be used to buy props which will be available for testing by KR builders on their planes. This will enable you and the rest of us to learn from testing different props on different planes and engines. Hopefully, this will help in making that final decision on exactly which prop will best suit your needs. All of the details have not been worked out on using a prop from the prop bank but I am working on that. This program was something that Mark Langford started and has now been turned over to me. As of today, there is $701.00 dollars in the prop fund from donations by KR family members and the sale of the KR stickers. We all know that $701 will not go far towards purchasing props. Therefore, I am appealing to all of you to donate to the prop fund. This can be a money donation or a prop donation. If you do have a prop, but do not want to donate it, yet are willing to loan it out, then e-! mail me with the details. Money donations are accepted via PayPal to my account which is my e-mail address flykr2s@wi.rr.com or you can mail it to me. My address is: Mark Jones 615 Wexford Circle Wales, WI 53183 Any donor props can also be shipped to the above address. The Prop Fund Bank is public information and will be kept that way. A periodic update of the amount of funds collected will be posted as well as any prop inventory that becomes available for your use. This can be a good program so let's make this work. Please make a donation.

There is NO WAY you can get a retract gear system that is safe and relaible to weigh as little as my Dan Diehl fixed gear system. Common sense tells you that you have to have just as strong main gear legs so that is nearly the same, wheels and tires and brakes, so that is the same. Then, the part count goes up on the retract because now we have to have the linkages or jack screws, electric motor if that style, & wiring, hydraulic system if that style, and indicator system for gear position. The shear increase in part count makes it obvious that the retract will weigh more, the question is just how much more. The coolness factor is not worth the added weight and drop in performance. Look at the Loehle P5151R vs the P5151. Same max speed, 10 mph cruise speed increase. For the KR1 no big deal, but for the KR2, the added weight surely means lower payload. Remember, added weight in empty weight reduces payload because you still have the same gross weight! If Troy Pettiway, one of the fastest KRs flying, and Marty Roberts, another fast one, and Steve Alderman, another fast one, felt that they would get significant enough speed gains to make it worth the added weight and time on this plane, trust me they would have put them on! You can install a Flight Director too in your KR and it will work, BUT does it make sense and is it necessary to match the mission of the plane, or is it just the latest greatest toy available and money is burning a hole in your pocket. If so, so be it. But do not believe that you can make a retract system come close to the same weight as a well designed fixed gear system. That defies common sense. Comparing a car's heavy duty leaf spring to my light weight fiberglass gear legs is truly apples to oranges. Not trying to talk anyone out of doing it, just want you to see both sides BEFORE you buy parts and change your install and begin cutting....

John's is a perfect example, his is reliable and relatively light. I weighted mine after fabrication and the assy weighed the same as stock gears with my compressor and plastic air tubing and controls it's about 7 lbs heavier. They deploy by gravity. Allot of work to fit them up is required.
