Were you happy with the height above the floor that the horizontal made (the bit that your foot rests on)? I have a set of pedals made to plans and have decided to hang them from the shelf to make room for the nosewheel well and retract mechanism, but the horizontal sections are now too low to the floor. I was wondering what solutions you guys have come up with. I thought by shortening the arm and keeping the cable attach point the same as the plans call for (just closer to the horizontal piece now), it will just take a little more movement at your foot to give the same movement at the rudder. I can't see this posing any problems, can you? I suppose I could move the cable attach point further out to compensate but there isn't enough length left to compensate completely. By measurements I have taken, I will have to shorten the pedals lever by about 60-70mm.

You will note that I had to add a second layer of 1/4" ply to the lower shelf to move the pedals back from the firewall to give the clearance for the master cylinders. There are a few more pictures at the krnet.org site that I posted several days back.

I'm tall, 6' 4", and that puts my feet on the pedals at a rather flat angle. That caused me to drag the brakes when I don't intend to even though I moved the fixed pedal back from the toe-brake pedal with some washers. My fix was to add a piece of wood trim called "half-round" to the top of each fixed rudder pedal so I must roll my foot a bit more to actuate the toe-brake. I think I used 1/2" thick stock and applied it with JB Weld. I love my set-up and haven't had a single problem with it in the 180 hours to date. I do wish I had 3 or 4 more inches of leg room though.

I hope so. If not here is a quick and easy way, provided the mag has not been opened and the internal timing altered. First identify which position on the mag is the # 1 position. In reality it does not matter, except that the existing harness will probably only fit certain plugs because of the length of the lead. If you attach the harness portion to the mag and lay the leads out to where they will be installed. You then take the mag and rotate it by hand, you will hear the impulse coupler snap and the leads will spark. Continue to rotate until the lead for the #1 cylinder sparks. You must remember that the impulse coupler is designed to retard the timing and spark at TDC and once the engine is running the timing will automatically advance to it's pre determined setting in some cases that's 26 degrees. In theory all you have to do is set the engine to #1 cyl TDC and the mag to #1 cyl TDC and install the mag, and the engine will run just right. To help install the mag in the engine without loosing the #1 TDC position, there is a feature that allows you to remove the cap with the leads attached (it only fits on one way anyway) and there is a hole in the top of the distributor cap designed to fit a small pin like tool in a hole that locks the mag in the TDC position, allowing you to put the mag on the engine without the gears inside the mag moving from the TDC position. The size of the pin is somewhere between 1/8 and 1/16 of an inch. Care must be taken with the tool inserted to insure that the coupler is not rotated because rotation with the pin in place will cause the plastic gears inside the mag to break. A tip that will help is that when the coupler snaps, it generates forward momentum due to spring action. To set TDC at the correct hole, you let it snap and then rotate it backwards just enough to get the pin to insert freely. Although the buzz box is helpful, it is useless until the above procedures are accomplished. I have used a standard automotive timing light with equal success in fine tuning the timing. I usually do this only on an initial installation and always with the prop removed. It requires that you mark the prop flange with a TDC mart and some degree indicators. Hope this helps. If I missed something let me know.

To: Message-ID: <436D48F8.00000D.00356@DANHOMECOMPUTER> Content-Type: Text/Plain; charset="iso-8859-1" Well, today, we did time the mag. Orma, that is very good information and we had already done those "prerequisite" things. Steve says that it should be timed at 29 deg before TDC. Well this Mag has a 25 deg lag, so, if we did that, and we did, it would try to start, firing at 4 deg BTDC, theoretically That did not work so well. So, we backed it up about 3 Deg and now it is starting on second blade. We are going to time the electronic with a timing light. It would be interesting to know how you time the mag using a timing light. For those of you who have been following our cowling and carb air inlet installation, I can tell you that the design as it is at this moment is causing the engine to run extremely rough. That is because I have caused an air restriction in the cowling parts, which I am working on. Also, we decided to make new wing gap covers today. We should start calling them WGC, sort of like WAF, then I would not have to spell it out every time This time I layed it up in the hangar on a piece of 8' shelf board that I got from Lowes for about $9. I used a layer of deck cloth on both sides as on the first one, but only put in 3 layers of glass. Jerry made me get started on installing them, much earlier than before. In fact, they were a little bit too tacky, but that is better than too cured. I put one layer of that "seran like" wrap on one side and left it on as it will conform to the wing and protect it. That side went directly on the wing and we taped the cover on with vinyl electrical tape. This tape will not cause any damage to the wing surface and it stretches very well. Jerry and I agree that it was much easier than using the big roll of the stretchy plastic wrap. This one looks very good and will be the one that we use. Amazing, only had to build this one twice to get it right. See N64KR at http://KRBuilder.org - Then click on the pics See you in Mt.

I got the nose gear repaired and had every thing ready for a 4pm flight. Take off was uneventful just like it should be and quickly climbed to pattern altitude. I was staying in the pattern to practice approaches. I turned down wind and started to wonder where all the breeze in the cockpit was coming from. @$%@%^ the canopy is open -- I can't believe I did that again. I left the pattern and slowly climbed to work at the problem at hand. I finally was able to get one side latched and then the other side was easier. After that I climbed to 3000' and headed out to meet a balloon that was about 10 miles out to the west. I stayed well away from him but it was sure pretty in the setting sun. I made a big turn and headed back towards the airport. Again I was behind the curve on keeping the bubble centered up and it has a real effect on the performance. I did not fly above 125 mph today. But still flying for just a few minutes concentrating on the rudder and watching for traffic. I looked down for the airport and it wasn't where I thought it should be. I looked forward and said to myself " ya know that lake there is a lot further from the airport than this " I gave a glance back and saw that I had over flown by several miles. So we made another big turn and started to make practice approaches at 3000'. I took it to power off stall a couple times and was able to keep it straight and level without much effort. I gave it power and recovered after feeling the buffet for a few seconds. The airspeed was indicating 40 mph during the buffet. Total altitude loss was about 200'. ( sorry Mark L. still not ready for things floating in the cockpit) I worked my way around and down to pattern altitude and started a for real approach. I did not get it big enough and ended up not turning to finial early enough. I was able to get lined up in plenty of time to stabilize finial glide and set flaps. I still crossed the threshold at about the right height but still a little fast. I tried bleeding off the speed and I'm sure I could have gotten it down and stopped but I made the decision to go around sooner and get it right. She quickly climbed and we went round to do it again. This time I had eighty on finial and then started putting in the flaps, reduced power and started to pull back slightly and the speed started to bleed off. Crossed the numbers at 70 mph and 15 ft above. Into ground effect and keep adding back pressure. She went a long ways like this like 1200 to 1500 feet. And then it happened the sweetest two little chirps I ever heard. I had to fight the urge to let the nose down and kept adding more and more back pressure until she settled down on her own. The coasting speed dissipated quickly and was very close to making the first turn off. But I had not been trying to do that and I just ran her to the end and turned off and cleaned her up. I called clear of active and taxied back to the hanger. The total time was 45 min. and the engine temps are acting great. Oil today topped at 175 deg. Exhaust were running around 1150 and the highest cylinder was 350. Number 4 cylinder is the coolest running about 50 deg. under the others. The aerocarb is performing well for me and this engine is incredibly strong. I'm getting happier every day. Thanks to all who had advice on landing and speeds. Most of what I was told I knew but I needed the positive reinforcement. to bring the act together. I know how it feels and looks now and if things are not going that way in the future I'll be going around to get it right. I may have to do this again in the morning. Have a good night guys.

My KR does a better job of staying coordinated than I do with my feet just resting on the pedals.

If you release the pedals, a Corvair powered KR will yaw to the right. You will also find that after several hours of flight the left foot is begging for some relief and you will start thing about trim tabs on the rudder. I have a spring and ball chain arrangement that I can adjust for cruise flight and completely remove my feet from the pedals and the ball will track straight. This winter, I am considering installing a MAC trim servo and tab in the rudder.

Mine is only that way when climbing out. Once I get up some speed, mine's like Larry's, just take my feet off and it'll straighten itself out. I DO have a "heavy" left wing though, although I suspect that's due to 150 pounds in the left seat, and none in the right. I plan to remedy that with a 5" round aluminum tube fuel tank in the right wing, killing two birds with one stone. I did another hour and a half this morning, playing with static ports and fuel totalizer, and another four landings on short strips. I flew 2.5 hours and did 22 landings at Fayetteville on Thursday, with the goal of perfecting the power off landing from downwind. The static port tweak got the bottom end of the airspeed indicator to be fairly accurate at the expense of the upper end, but the VSI is still crazy. Need more investigation there, but it makes me feel better that nobody else can figure it out either. Today I added a backup electric fuel pump, and tomorrow I'll wire it to the backup UPS battery mounted in the tail. Redundancy will be mine, and CG will move aft a little. I talked to Kim McCutcheon (president of the Aircraft Engine Historical Society and mechanical engineer A&P) today , and he commented that it takes an engine out landing to start thinking like I do now...going everywhere at 12,000'. Next weekend it's a 400 mile trip to Daytona Beach to Corvair College #9. Lots to do before then...mainly wiping all the oil and exhaust residue off the bottom for the first time in 35 hours. 73 hours on N56ML to date! I did manage my first high speed "missed approach" at Hazel Green Thursday, for Jim Hill's benefit. He was setting the timing on his KR at the time. When I landed at Moontown a few minutes later, my phone was ringing. Jim said "You mustav been going at least 200mph! Sweet sounding engine!". Yep, first time...

I have a "heavy" right foot on climbout and a slightly heavy right wing at cruise. Hummmmmmmmmmmmmmmmmm...........

Making airplane noises is a lot more fun. Some times I forget the small things that I have done. Since the mag comes new with a blank harness cap ( for those who do not know, the mag and the harness assembly are sold separately), I made my own leads from automotive wires. I drilled that blank cap with a bit that was smaller then the wires and forced the wires into the holes. I use normal auto spark plugs with the auto wires. Once the mag is set to fire on the correct cylinder, I simply use an induction timing light and the marks on my prop flange to time the mag to the engine.
