I never flew like this as my gear was fixed down by the previous owner and would produce too much drag, I ended up replacing the whole undercarriage. regards Barry Kruyssen Cairns, Australia RAA 19-3873 kr2@BigPond.com http://www.users.bigpond.com/kr2/kr2.htm ----- Original Message ----- From: phil brookman To: krnet@mylist.net Sent: Monday, May 23, 2005 8:48 PM Subject: KR> kr retract gear mods and angled blocks hi does anyone know what the angle is on those 3 blocks that join the gear to the main spar and what do people think about adding a small plate at the end of the gear to shift the wheels forward and thus place moreweight on that tail the small plate would also give it more ground clearance .i see torsion loads being applied to the bar and brackets but should be ok i think anyone done it. also to get the plane sitting higher has anyone fitted any spacer blocks on top of the retracts between the spring gear phil ------------------------------------------------------------------------------ No virus found in this outgoing message.

A friend had to move his wheels 4 inches forwards. He used a 3/8" bar , the same width as the gear leg. This was bolted to the place on the gear leg where the axel usually sat.In his case it pointed forward, parallel to the ground. He moved the axel forward 4 inches to this new location.His ground handling problem was solved but it did look a little peculiar. I guess that you could do this forward, backward or if you required more ground clearance, straight down. It proved strong enough. Regards Harold Woods Orillia, ON.

Any mis- alignment of the hinges will make your control surface bind. To maintain alignment when mounting them is maintained by using a proper diameter steel rod inserted through the hinges and when you swivel the control surface spar ( elevator or rudder) it must be free moving and there can be no flexing of the spars. If you are replacing the hinges because they are galled and there is play in the hinge, consider re using them. Either use sintered bronze bushings and redrill what you have or even better use Garlock DU series bearings what they are is a steel jacket that has a coating on the inside that is lead impregnated teflon and the claim is that they are good for 5000 hrs.moderate use. If your hinge pins are AN3 aircraft bolts 3/16 inch diameter. the Garlock bearings are only 1/4 inch O.D so all You have to do is redrill your hinge pin holes to 1/4 inch , they are split down the sides so they'll maintain tension in the hole and won't spin. On my KR 1 I have 3 inspection holes 1 on the rear turtle deck to inspect upper elevator cable pulley, 1 on the left side to inspect the lower elevator cable where it attaches to the bellcrank and the other on the right side and I cover that hole with a 4 3/4" domed inspection cover used on inspection holes in fabric covered airplanes Hope this all is of some help to you ------------------------------ Message: 8 Date: Mon, 23 May 2005 20:31:17 -0400 (Eastern Daylight Time) From: "Dan Heath" Subject: KR> Retract Gear To: Message-ID: <429275D5.00002D.03764@DANHOMECOMPUTER> Content-Type: Text/Plain; charset="iso-8859-1" I am going to say what most KR builders already know. The only real solution to problems, note I said problems, with the retract gear, is to replace it with a fixed gear. I went through 3 failures of the retract before putting on a fixed, on my first KR. If you are not having problems, then, don't fix what ain't broke. See you in Mt.

The only problem is that all of the boxes come with at least 2" tube. So, I guess I would have to make all of my own boxes, which is not a bad idea because these are way too expensive. Well, anyway, here it is with most of the engine stuff installed and hooked up and ready to go. I am now trying to fit all that stuff under the cowling I don't know how Mark and the others got all their stuff in this little plane. What if I had a turbo, where would it go?

Moisture and dust will create mud which does not pass pressure very well. Fibers soaked with moisture swell up and don't pass pressure very well. Filtering is a good thing and should be done. In advance of the filter should be a moisture trap which uses a material like Desiccant which will dry the air and show a visible indication that moisture has been present, enabling the pilot to get the system serviced. My KR does not have a moisture system. My pitot and static tubes are simple soft 1/4 in L shaped aluminum tubes. Moisture must be sufficiant to climb up hill 3 inches to get into the tube. then it must climb another 12 inches to get to the instrument. I will only fly in light rain and then only if I can see the other side of it. I could probably use an inline filter. I would be cautious in installing one too low in the system, would not want it to came in contact with moisture.

The filters don't effect calibration, tried and proven for many years our club gliders. We change them every year, at a few of dollars each, no problems. I've never seen any evidence of moisture but I have seen dust in them (very dusty when towing gliders behind a Pawnee on a dirt strip). regards Barry Kruyssen Cairns, Australia RAA 19-3873 kr2@BigPond.com http://www.users.bigpond.com/kr2/kr2.htm ----- Original Message ----- From: Orma "a small inline fuel filter to try and prevent any moisture or insects" You can call me cautious Clara if you like, but I see a small problem with the design of a system which uses a fiber filtration product with the hope that it might trap moisture.
