You should have your heading offset once airborne to maintain the track over the ground but the ball should always remain in the centre, ie., no additional rudder is needed.

This can be a problem tuning from base to final when you're low. You have plenty of warning when a stall is about to occur in a KR just by the feel of the plane. It sinks like a brick, or a manhole cover on edge when it gets slow. During some full power climb outs I've had it down to 60 and still climbing. I just lower the nose until it gets to 70 and hold it there and the rate of climb will come up a bit. I just did a test flight last week with some new parts in my engine. No more oil cooler. I have copper tubing wrapped around the lower intake just downstream of the carburetor for hot oil to go through. Also I've sealed off the upper baffling so no air will leak through. So far I've noticed about 90 deg. F cooler cylinder head temp. I don't know about the oil temp yet. More to do. -Joe ------------------------------ Message: 6 Date: Wed, 13 Jul 2005 05:06:11 -0400 (Eastern Daylight Time) From: "Dan Heath" Subject: KR> Ester and plastic sheeting.

I would like to hear your thoughts on why you prefer a looser tailwheel connection. With my "nearly tight" connection, using Maule tailwheel springs, I get ground handling that I would consider very similar to a nose wheel Cessna such as the 150 or 172. I feel very little difference in the amount of pedal needed in tail up or tail down and little if any change during the transition. My steering seems very positive with very little pedal movement. I've had no problems with tailwheel shimy at any time with two different tailwheels. My setup works well on grass and any additional forces or pressures from operating on grass does not appear to have caused any damage or un-do wear on the system. I've never tried my KR with the cables looser nor have I ever taxied other aircraft that have had a looser cable setup. My 15 hours of tailwheel time before flying my KR was long enough in the past that I have no way of comparing it to my KR handling. I do, however, see a lot of tailwheel aircraft with sometimes VERY loose cables to the tailwheel. I'm just not sure what I'm missing out on that would cause me to want to change my setup. Your thoughts would be appreciated.

Your thoughts would > be appreciated. We all know that I'm no taildragger expert, but mine are set up with no springs at all, and pretty loosely. I did this on Troy's recommendation. He swears by it, and since it works for me, I can only assume it might make taildragging childishly simple. Having said that, Larry's apparently works too, so maybe it doesn't make a big of difference! But the logic is that if you land carrying some rudder to keep lined up with the runway, when the wheel touches down it won't be straight and might jerk you around a little. If the wheel has some slop in it, it'll just pivot to where it wants to be and you'll never even notice. Of course, that's proabably what springs are for, but springs create drag, and we wouldn't want that! Since I'm a sloppy kinda pilot, it works for me. I must say that having finally figured out how to land a KR (which has nothing to do with whether it's a taildragger or a tri-gear), I have to wonder what's so difficult about ground handling with taildraggers...

It was like driving a go cart. I put expansion springs on the tail wheel cables to allow for some give in case the wheel was at an angle upon landing. The compression springs that I originally had on it were too stiff for that little wheel and it was like a direct connect. The only tailwheel plane that I had flown before that was an Aeronca Champ and compared to the KR,,, well, there is no comparison. The KR is way easy because it goes where you point it, when you point it. I only hope that this WannaBee does as well. See you in Mt.

Although some of the trainers allow for use of the rudder alone to lift a wing during slow flights and stalls, this is mainly done by CFI's in training to build control confidence in the student so that the student gets used to small inputs, and being smooth, not because the rudder is the preferred control device. Some ultralights fly with only rudder and elevator due to their slow speeds allow for the application of rudder to make a turn which momentarily skids the plane, but slows the in board wing causing it to drop, while speeding up the out board, causing it to lift. The trainers do the same thing, and can "get away" with using this uncoordinated approach to turning. It is also to build confidence in the student for later spin recovery if ever it has to be done. Application of ailerons then will only cause a tighter spin. By design the rudder is only used to maintain coordinated flight to correct for yaw. The wing washout is by design an attempt to maintain some aileron effectiveness as the aircraft slows down. Not always can they maintain positive aileron control near the stall, but that is the effort anyway. It is also more primarily apart of the design to insure that the stall occurs at the wing root, and not the tip so that the stall characteristics will be more forgiving, and more control is preserved than would be otherwise, (stall occurring at the wingtip first).

To update where I am at... and lessons learned... I pulled the piece off tonight... 1.The areas of the mold, that I used duct tape on, the piece still came off... but for whatever reason, the resin melted the tape and caused the resin not to cure in that area. 2. The piece is really not straigt enough.. as I've stated there are slight dips and hills in it because of the mylar 3. I dont know if its the resin I used or what... but the piece is VERY flexable.. about that of cardboard paper,.... and not stiff like I would have thought 4.Round one goes in the trash. Although I might keep it to laminate up foam .. I hate to waste a 100 bucks. Lessons learned. 1. Use a good epoxy .. and not impact polyester resin from the hardware store, you'll have a little better control of the pot life when you mix it. I only had about 15-20 min before the stuff set to the point I couldnt use it. 2. coat the mold with monokote, or the like, and dont try to use 10 mil mylar. it just didnt work. the mylar ended up with slight dips in it that ended up being transfered to the piece. 3. always by twice as much cloth as you think your going to need... because you will end up building the stuff twice. 4. The carbon fiber ribs that I used to ( I thought it would anyway) replace the foam core structure is just as flexable as the rest of the glass 5. pulling bits of 1/2 cured resin out of your arm hairs hurts. well hopefully part doux will be better then this piece. thanks everyone for the information. -Jeff ------------------------------ Message: 20 Date: Wed, 13 Jul 2005 21:24:17 -0500 From: "Mark Jones" Subject: KR> First passenger To: "Corvaircraft" , "KR Net" Message-ID: <002a01c5881b$23106a20$6401a8c0@wi.rr.com> Content-Type: text/plain; charset="iso-8859-1" This evening I made a flight with my first passenger. The passenger got in my plane and hid till I was up around 4000' and then he appeared and landed right on the top of my control stick. That darn house fly made me feel like Charles Lindberg when he crossed the Atlantic and had a fly for a passenger. The additional weight of this passenger was not a factor. Other than the annoying buzzing around the cockpit, I could not tell he was in the plane. Another great flight!!!!!!!!!

Mark Your first passenger is a real expert, its a shame , or maybe not, that he couldn't comment of your flight/landing.

I guess it's "whatever works for you is the > way to go". Hey, you just asked WHY, not if it actually WORKED! Reality is probably that the tailwheel is so light that it just skitters along when you land with it cocked off to one side, so it probably doesn't matter one bit, like you said. On my plane the tailwheel doesn't have much to do anyway, since it's up almost immediately after adding power, so what do I know anyway?
