Turbocharging does not increase HP, it merely provides full HP at altitude. Secondly, the prop speed reduction unit can reduce pulse waves from your crankshaft to the prop and help increase motor life.

In the last year two guys on the CorvAircraft list pulled Subarus off their airplanes and weighed EVERYTHING, including the water, firewall forward. The end result was something like 280-285 pounds. The consensus on a similar comparson for the Vair would be 240-245 pounds. With the small diameter prop we use on the KR, you can turn the "standard" CorvAircraft engine up to 110 hp easily, and I'll bet mine will do 130hp (while weighing a few pounds less, due to the lighter VW pistons/cylinders). And these things are just loafing along at 3500 rpm. The 150 and 180 hp versions used exactly the same bottom end (well they nitrided the crank on the turbos, but otherwise identical). The thing that makes me nervous about water cooled engines is that "extra" mode of failure, a leak. A water-cooled engine with no water won't last 5 minutes at the high power settings required to stay aloft. Turbos fail too. Constant speed prop? There's another mode of failure. Ask Steve Makish (he had a Sube too, and replaced it) what happens when one entire cylinder of a 6-cylinder Corvair quits. It's down a few hundred RPM, but not enough concern for a precautionary landing! He's had a VW Type 1, a Type 4 , a Subaru, and now the Corvair on his KR2, and I think now he's finally happy. See a photo of his engine in his KR at http://home.hiwaay.net/~langford/snf2002/020409054.jpg , and more at http://home.hiwaay.net/~langford/snf2002/ . I won't kid you though. I'm extremely prejudiced in favor of the Corvair...

Sorry I missed out on the conversation, but I can't imagine where the twisting forces are going to come from that are going to make these hinges rotate. I suppose you could argue that over a long period of time the wood would "creep" and lose the torque on the nut, but if that's the case, we're all in trouble with regards to wing attach fittings, among other things (yes, we should check those every year during the condition inspection). If I'd had the good sense to think a little harder and utilize this method, I'd just T-88 the bearing to the big washer (4130 spacer), and the washer to the wood, and I'll bet between the tension on the bolt and the epoxy, there's no way it would ever rotate. And there's always spotwelding the two together in three or four places, but I really wouldn't worry about it if it were my plane, but I would T-88 the thing. I've epoxied my WAFs to the spars, and all brackets where it made sense. I'd use red Loctite 271 on that "H" bolt too, personally, and forget about it. I like the KR U-bracket idea too, since that would put the bolt in double shear (or at least a double case of single shear :), but a steel clevis might even have nicer geometry than the KR bracket, and wouldn't require spacers. I'll have to look around and see what off the shelf part would work best. I may have to go downstairs and play around with some rod end bearings, and keep my eyes open while digging through the McMaster-Carr catalog...

So, I have to route some wires to the wingtips. The trouble is, the wings are closed (my KR has been flying for 8 years). I did not build the plane, so I'm not too sure how KR2 wings are built. I have been told that KR ribs are made of foam. Therefore, I thought I might be able to use a very long piece of hard wire to poke through the wings, all the way through the wing gap seals. Now, after having had a look at the construction manual, I have doubts. There seem to be some plywood ribs on the way. Is that correct? If yes, any ideas on how I could route these wires?

The inner bearing in a REB is limited in it's movement. That bearing will not rotate past the point where a bolt would come into contact with the outer casing. With the eyebolt, or washer (preferably), compressed against the bearing the rotation arc of that attach point would inhibit what is being discussed from happening. I just don't see how you could make that arrangement lock up. Like I said, I just may not be seeing the forest for the trees though.

As per the drawing, bolt H or AN3-11A that holds the female REB to the H/S spar does not have a locking device. What will stop it from coming loose? or rotating slightly? Or should it have a thread lock fluid on it? The site does not discuss this. The normal KR2 hinge which I do not like has two AN3 bolts with self locking nuts to hold it and stop it rotating.

I'm not arguing, just wondering how you see >that happening. ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ In order for my concern to become a reality the bolt holding the R.E.B. and the eye bolt would both have to rotate in their respective spars at the time. Bolt a R.E.B. and an eye bolt together. Hold them so they will rotate in the vertical plane. Now slowly twist them while still trying to rotate them in the same vertical plane as before. How many degrees of rotation do you get before lock-up? I'm guessing 20 or 30 degrees will do it. I'm now convinced I'd do the double eye bolt and one R.E.B. on each hinge or the channel and one R.E.B. on each hinge. That to me would be a 100% fix. In either of those cases the only rotation possible is the bolt holding the R.E.B.(or the R.E.B. on the bolt) and it will only rotate to the point that the outer portion of the assembly holding the bearing strikes the bolt going through the bearing. Even in this position there would be no binding or lockup in the system. I'll admit the chance of failure I suggested is PRETTY SLIM. I'd not advise anyone to go back and change anything already done. If I were building my control surfaces again from scratch I'd sure use the R.E.B. but a double eye bolt and not the original R.R. hinge design I have now. Your results may vary.

It works for any pin hinge. After you attach your aileron, pull the pin out. Grind the center eye off the aileron hinge and two eyes off the wing hinge. Remember, only grind off the eyes, do not cut the hinge into two piece. This leaves you an 1.5" slot in the middle of the hinge. Cut the pin in the dead center of the slot and bend those two .75" pieces 90 degrees. Now you have two pins that you can take out from the center of the wing. Just more food for thought.

He said that scratch built airplanes like the KR is not type accepted. Because there is such a variation in the construction, design gross weight, and horsepower, they approve each airplane on its own merits. So, we in the United States can't help you with your documentation. I believe that both Canada and Australia do have specific criteria for the KR's that are built in those countries. Perhaps one of these owners could assist you. Best of luck in your project. I have learned a lot and met a bunch of neat people because of my project.

I know this is airplane's and not car's, but every thing writen on elect vs mech. fuel pumps is elect pumps dont have the same suction power as mech pumps do. This is why you always find a elect. pump at or in the gas tank pumping gas to the carb or injectors, but you can stick a mech. pump on the motor it will work just fine. Even on the certified injected engines the motor run's on a mech pump,the elect pump is just a back up to get back to the airport, i guess theres enough head pressure to make it work. Now having said all off that, i guess the best way to do it, would be to mount one at the tank and then one close to the carb if your not going to use a mech pump.But then agine, it's acording to if your going to use the elect pump as a back up or as the main pump. anyway let's do some work Anthony. -----Original Message----- From: John and Janet Martindale [SMTP:johnjane@chc.net.au] Sent: Tuesday, January 07, 2003 5:12 AM To: KRnet Subject: KR> Alternative thoughts on fuel pumps Hi folks There would appear to be two main reasons why a electrical fuel pump may be needed.

We have both known each other way too long for us to think that so please don't anyone chime in with a "you two lay off it" OK:-) What is good about a forum like this is to be able to clear up concerns, whether it confirms ones' thinking or disqualifies that same thinking. Here is a picture with a piece of alum. substituting for the eyebolt. http://rvflying.tripod.com/p1070002.jpg With a washer placed between the REB and the alum. the REB rotates to it's max deflection without ever having the casing touch the alum. As I said before, the inner bearing is not full pivoting. The bearing will only rotate until it hits in internal stop which does not affect the smooth rotation of said bearing. I can't make it lock up. If the eyebolt were as wide as the outer casing, though it is not, it would rub without a washer. My take on this, and it is only mine, is flox the head of the bolts to the spar because these are imbedded in foam. Run these thing down with some loctite, put a washer between and put a bolt in. The two eyebolts is a good idea although I might be more concerned with having two holes drilled in the spar so close together. What I really liked was how easily this arrangement lined up when I built mine. The RR method is a pain in the butt to line up compared to this. With a bearing to rotate on a bolt, you get muck less friction. I just think, all things consider, this is a very nice arrangement. The shaft of the REB if flat so that it can be cranked down with a wrench. The way I see it, when you do a preflight you always check the hinges. Look at it, if the two are not parallel, line it up. Like I said, even if it touches, I can't make it lock up.

That's what this forum is for. Discussion of ideas. I've also known you long enough to know you won't let me get by with a statement unless I convince you I'm right. :-) I accept your answer on failure mode if one of the two components in the hinge rotates. My failure mode concern (AND IT'S PRETTY SLIM) is if BOTH components in the hinge rotate. Take the items in your photo. Orient the alum piece in the vert. plane. Move the R.E.B. up and down in the vertical plane as if installed on the elevator. Slowly rotate both components while still moving the R.E.B. up and down in the vertical plane. After BOTH components rotate 20 or 30 degrees you will start to get very limited movement of the R.E.B. Yes, this failure mode would be very remote. The only way I could see it happening is because of the two dissimilar materials, wood and steel, expanding and contracting , along with airframe vibration or something. Both components in the same hinge would have to loosen in the spars at the same time for a problem to develop. Again , pretty remote. The same thing would happen to the R.R. hinge if only a single center bolt were used on each side of the hinge and they rotated. I had no problem aligning the R.R. hinges. I used the 3/16 inch rod through all hinges at the same time when mounting as suggested in the plans. It worked just fine. Strike a pencil line down the centerline of the spar, align the rod with the line, and drill the mounting holes for the bolts. I later used the same rod on my gullwing door latch assy as lockdown rods. I still wish I had the Dr. Dean style hinges instead of the R.R. hinges. I think the Dr.Dean style is MUCH better and probably would be good for the life of the airframe. Your results may vary. :-) Larry Flesner ------------------------------ Date: Tue, 7 Jan 2003 08:04:40 -0600 To: "kr net" From: "JIM VANCE" Subject: Spinner Diameter Message-ID: <000a01c2b655$d2310ae0$0300a8c0@VANCE> ------=_NextPart_000_0007_01C2B623.6DC17220 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable I have finally finished my windshield and am ready to mount up the = engine to form the cowling. I am installing a Type I VW with a rear = drive. It should permit a very aerodynamic nose. I don't want to buy my propeller and spinner until I am able to come up = with the final weight. My question is: what diameter spinner is others = using on a rear drive? Can I plan on a six inch diameter, or is eight = inches more realistic?
