What a beautiful morning for flying. I headed over to Lake Michigan and went north up the shore line to Oshkosh and circled north of the field. Then I went west before turning back south to Hartford for a beautiful approach and landing. The only thing about this flight was that it was pure fantasy as I never left the hanger. It was one of those flights where you get in the KR and make airplane noises with your eyes closed while pretending to go somewhere. For those of you who do not know, my engine is torn down right now while I am waiting on parts to arrive for re-assembly. However, I did install a Narco 11A Com this morning. The radio works great and is a huge improvement over a handheld. Now the tower can't say I am scratchy and unreadable.

So for the moment, I'm still in my shed "Shed Flying" rather then out at the airport, wishing I was able to go " hanger flying" I guess my point is Mark, I am glad that I am not the only one who makes airplane noises GAWD!!!

Incorrect air inlet baffling on the front of the cowl caused my two front cylinders to over heat. This in turn resulted in a cracked piston and a broken ring in the #5 cylinder. The resulting compression on this cylinder was 14/80. The opposing #6 cylinder had problems also with a compression of 25/80. The rings and piston on #6 were not broken or cracked but the rings were no longer sealed and the gaskets were leaking as were the gaskets on #5. The front cylinders were blocked from any direct cooling air as you can see in this link http://mywebpage.netscape.com/n886mj/baffles.html . Notice how the air inlet baffles cover the entire front of the cylinders. A costly design mistake on my part. The top half of the cylinders must be exposed to the inlet air. The strange thing is that my FSDO inspector did not catch the bad design nor did anyone else who looked over my plane. The photos on the link above were posted long before I made the first flight and not a single person on the net caught the design flaw either. That really surprised me since everything posted on the net is picked over with a fine tooth comb. Oh well, my loss, your gain since you learn from my mistake. I have a total of about $250 in repair parts (one piston, one full set of 6 piston rings, lifters, head gaskets, base gaskets, top engine gaskets, valve cover gaskets, push rod tube o-rings, push rod guide o-rings, etc.) headed my way and should be here by mid week. I have already surfaced my heads and cross hatch honed the cylinders and cleaned up the five good pistons. The re-build should be a piece of cake. If you guys remember, I had the EFS-2 crab which was too small and replaced it with a EFS-3. After installing the bigger crab, I did not get any performance increase and was doing everything possible to figure out why. I finally purchased a differential compression tester and that revealed the problem. Looking back over my flight records, I see where my oil temps went from 190° to 220° back on 4-7-05. I also made a notation that two days later, I had an oil temp spike of 260°. These temperatures were discussed in depth with very knowledgeable Corvair guys and I was assured by them that this was nothing to worry about. Of course I worried anyway and made several changes to my oil cooling duct to improve the temps. I honestly feel that the damage was done during the flight on 4-8-05 when the oil spiked to 260°. Since that day, I flew the engine for an additional 23.8 hours. Cruise ranged from 135 to 145 mph and climb out on take off was 1100fmp all the while basically flying on four cylinders. This is a testament of just how strong the Corvair engine is. I am extremely excited about getting back in the air with a healthy engine and seeing what increase in performance I get. Another point is that I only had one cht probe located at the GM stock location between #1 and #3 cylinders on the head. I highly recommend getting six probes for mounting under the spark plugs with a six way switch to monitor all six cylinders.

To: KRnet Message-ID: <42ED3D08.7060906@spots.ab.ca> Content-Type: text/plain; charset=ISO-8859-1; format=flowed Hi Mark, Live and learn I guess, I am amazed that no one picked this up, but your system really looks good. These baffles would cause a turbulence inside. We all have a tendency to make our inlets too large and this causes turbulence, it is better to have small inlets for a smooth cooling flow. Absolutely no obstructions from outside through the inlets to the cylinders. A hard lesson for sure but I hope this is a heads up for others that are at this point.

It was hard to fly back in 97 but I thought it was important and in 2002 it was actually a fun event. I went as well in 2003 to help out Steve and to show the KR on the flight line. I have had several things come up at work in recent years that have prevented me from going. With that said, I am planning on going again in 2007 assuming I'm still able to pass my medical and I'm not off sailing. I think we should start talking up 2007 at this KR Gathering to try to outdo the 20 +/- KR's we had there in 1992. It would be a fun event. Keep flying and I look forward to seeing everyone at the Gathering.

Speaking of the Gathering, it's time for those that want to host the 2006 Gathering to start putting out their pitch for a location. That will give us some time to start checking out the proposed sites. Plan now to lay the ground work and bring your best sales pitch to the Gathering. Before making your pitch, make sure to check with all the locals to insure you have all the support you will need to make it work. I got in three hours of KR time this weekend. Covered the area today flying formation with a C-150 and an AcroSport. I have to throttle back to 1800 rpm to stay with them. I'm probably only burning about 3 gallon per hour at that power setting. I love the new RV pants. I can get an easy 170 mph at 2700 rpm from the 0-200. With a 200 fpm decent to the airport I'm getting 180. I really have to watch my decents with cruise power (2650rpm) or it goes right to 190+ mph. I brought my lower cowl home today to start to finish and repaint from my carb fire. I'd like to get it and the wheel pants done before the Gathering and if time, get at least the left wing repainted where I opened it up for the fuel leak. Too much fun flying to take it down for repair. Have a good week and keep on sanding, sanding, sanding..........
