Don't do the approaches at the speeds recommended for that aircraft, but rather at the expected approach speeds of the KR which should be slightly faster. Just 5 knots on each leg of the approach will make a big difference in your timing and mental prep for transition onto the runway. The faster patterns will better prepare you for how things will be happening faster. Also practice some power off 180 degree approaches to the runway to sharpen your ability to handle an engine out if it occurs. If it is windy, even better. This will develop your ability to plan better on a moments notice. Perform some landings with reduced or no flap landings, to illustrate a malfunction in your system or the float from most KRs with no flaps or speed brake. And make sure to practice some go arounds at differing points in the pattern. One last suggestion. Try several laps down the runway after roundout, where approximately 1400-1600rpms are left in where you hold the plane off the runway, and fly in ground effect the majority of the length of the runway, powering up at the end to climb out as normal. This time spent in ground effect for several laps would require at least 5-7 separate approaches and landings to get the same level of experience in ground effect. Get very comfortable handling an airplane here and your first flight will be much better. Then combine this skill with familiarity with your KR by doing several high speed taxi passes, and "hops" to fly in ground effect and note the difference with your plane. This skill and familiarity was in valuable on my first flight and gave me complete confidence that I could land safely, even with no airspeed indicator (debris from runway blocked pitot right after liftoff) because I knew what the sight picture in ground effect would be and how the plane would behave. The one thing on that flight that I WASN'T concerned about was landing due to this familiarity. Good luck and take it at your own pace, whatever that is...

So, I'll only add a short note. On my first flight I was as nervous as I had ever been, perhaps more so. So, remember to breath regularly and don't put a death grip on the stick. On my first flight I porpoise on climb out until I remembered what a Phantom pilot told me. "Don't grip the stick, rather place your hand around the stick and push, or pull the stick where you what it to go, block where you don't want it to go. See where the airplane wants to fly and correct it". Lastly, if you find your self shaking in the seat after takeoff and the plane seems to be functioning OK, tell the tower that you want to climb and orbit the field. That way you can calm down before time to land and your landing will be more under control.

I just thought I would pass along some food for thought. I am currently working on a good friend of mines airplane Getting it back into airworthiness status, and something happened yesterday that was really kind of funny. Well, we are currently changing the engine out to a Revmaster 2100 that was made back in 1982, but has no time on it. He told me that he wants to change the oil, prelube the cylinder walls, check the plug gaps, and check the valve clearances. All of witch is good precautionary maintenance since the engine has not ran since 1982. But when I told him we would change out the Oil filter he about had a heart attack. He presided to tell me that the filter was brand new and did not need to be changed. Well, I told him that it was brand new back in 1982, and was now 23 years old and needed to be changed. But he did not want to here of it. Well, being that I am the A&P signing off his plane we will change the filter, if I have to buy it myself. I probily will to, but I will stand my ground on this one. But the reason I write this is to ask each every one of you to check and double check your work. Ask yourself, is that glue aviation grade? or the cheapest you can buy. Is that bolt the proper bolt for that application? Or is it the best The hardware store had. Is the wood you buy the best you can get? It is up to each and every one of us to build, Maintain, and fly a good safe aircraft that we can be proud of.

Hello Net With an engine that has not run in the past 23 years, I would look a lot deeper then the items mentioned in the post. If the engine was pickled, it would probably be ok. If not, then the walls of the steel cylinders might have enough rust to cause it to fail at some point after the engine is back in service. I have opened several old VW engines and have always found that the crank is free of rust if the engine has had oil. On the other hand, the cylinders always had rust and the lifters were in bad shape also. The hot and cold cycles of winter and summer build up moisture as a normal cycle. Lycoming had engine failures due to this hot cold cycle allowing moisture to collect on the crank shaft and cause microscopic pitting corrosion deep enough into the crank to allow failure. The cost of opening that 23 year old case is less then $100. That seems like cheep insurance from my view point. As a professional AP/IA I would hesitate to put my name on an engine that sat that long without someone looking inside. Orma L.

In later years we just tapped into the oil galley and pressure fed the beast with a small pump prior to startup if it had been sitting for a while as over the winter. I always use STP as assembly lube as it has less of a tendency to leave the surface it's placed on than motor oil. Doug Rupert -- No virus found in this outgoing message. Checked by AVG Anti-Virus.

In later years we just tapped into the oil galley and pressure fed the beast with a small pump prior to startup if it had been sitting for a while as over the winter. I always use STP as assembly lube as it has less of a tendency to leave the surface it's placed on than motor oil. Doug Rupert -- No virus found in this outgoing message. Checked by AVG Anti-Virus.

Thirty minutes later, N886MJ returned to the earth and the pilot had one of those big KR/Corvair grins across his face that still has not faded away. So here it is guys and gals............................. YEEEEEEEEEEEEEEEEEEEEEEEEEEEEEHAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA I am now a true KR pilot. Does that mean I have to sing at this years gathering? Joe Weber flew in from southwest Wisconsin to witness the event. He even got the take off on video (which I have viewed at least 20 times since I have been home). The KR flew better than I ever expected. Take off and climb out were smooth as glass and absolutely no porpoising. I had intended to stay in the pattern and make one circuit and land but the plane felt so good that I made two circuits around the airport then left the pattern and headed north of the airport. My carb is an Ellison EFS2 which is a little too small for the Corvair but still yielded me a cruse at wide open throttle of 144 mph with the Sterba 56 x 64 prop I have. My static rpm is 2650 but I can not tell you my cruise rpm yet as I forgot to look. CHT temp at cruise was dead on 300°, oil temp at cruise was 180°, oil pressure at cruise was 50 psi, exhaust temp was around 1200° (I did not write that down but called it out to Joe down on the ground). Here is the best part....this KR is as stable as you could possibly ask for. Not one time did it pitch, wobble, shutter, or cough, and IT FLEW HANDS OFF. Just thought you guys would like to know......

After the aircraft had sat idle for six months, I inspected my engine with that cheap borescope that they sell at ASS (ProVision series), and I could definitely something that looked like a disaster in the making. So, I decided extreme measures: spray tons of WD40 oil inside the cylinders whenever I can, and build some preservation spark plugs. These are fake spark plugs, that end with a tube full of moisture absorber. At present, that absorber is... rice! But I will fill them soon with silica gel. By the way, if you need plenty silica gel, jut go to a luggage shop. There are big bags of them in every suitcase they have, so, just persuade them to empty a couple of them for you.

I purchased an engine that had been sitting for 4.5 years plus. When started it, the rust on the crank went through the bearings and seals, destroying the crank, rods, damaging the pistons and barrels. ----- Original Message ----- From: Orma engine has not ran since 1982. Hello Net With an engine that has not run in the past 23 years, I would look a lot deeper then the items mentioned in the post. If the engine was pickled, it would probably be ok. If not, then the walls of the steel cylinders might have enough rust to cause it to fail at some point after the engine is back in service. I have opened several old VW engines and have always found that the crank is free of rust if the engine has had oil. On the other hand, the cylinders always had rust and the lifters were in bad shape also. The hot and cold cycles of winter and summer build up moisture as a normal cycle. Lycoming had engine failures due to this hot cold cycle allowing moisture to collect on the crank shaft and cause microscopic pitting corrosion deep enough into the crank to allow failure. The cost of opening that 23 year old case is less then $100. That seems like cheep insurance from my view point. As a professional AP/IA I would hesitate to put my name on an engine that sat that long without someone looking inside. _______________________________________ Search the KRnet Archives at http://www.maddyhome.com/krsrch/index.jsp to UNsubscribe from KRnet, send a message to KRnet-leave@mylist.net please see other KRnet info at http://www.krnet.org/info.html ------------------------------ _______________________________________________ See KRnet list details at http://www.krnet.org/instructions.html End of KRnet Digest, Vol 347, Issue 115 *************************************** ================================== ABC Amber Outlook Converter v4.20 Trial version ==================================
