KR> Engine-out gliding
I'd heard that there was a real difference in the glide ratio of a plane with a wind-milling prop as opposed to one with a stopped prop, and thought I'd test it to find what the story was for my KR...because I figured it'd be good to know some day. So one calm morning I climbed to 10,000' and noted altitude, compass heading, direction, speed (best glide being about 80 mph), and then started a timer and pulled it back to idle. I glided all the way down to 2000' maintaining 80 mph all the way down (pretty close, anyway), and stopped the timer. Then I landed, replenished the two gallons of fuel I'd used, climbed back to 10,000', took the same heading, started the timer (same heading and altitude), and switched the ignition off to get a dead prop. Because I have a high compression engine with a short, light, prop, the engine doesn't windmill at any speed that I've tried, but certainly not at 80 mph. Again I glided down to 2000' , stopped the timer, and divided out the numbers. They were almost identical, and certainly within the range of any kind of measurement error. I only mention this for informational purposes, as it may come in handy someday for similar KRs. Another useful tidbit is that the glide ratio for my heavy KR2S is just over 12:1 (12 miles horizontal for every mile of altitude). I'm guessing that a low-compression O-200 with a larger and heavier blade might continue to windmill with the engine off, but I've never tested that scenario. I'm sure somebody else on the list has, however. Mark Langford, Harvest, AL ML at N56ML.com www.N56ML.com
KR> engine out take off
After blowing up an engine at night 20 years ago, I was a real Nervous Nelly in that particular plane at night from there on, but made myself do it anyway, sweaty palms and all. It didn't seem to bother me in any other plane. I have always flown with emergency landing sites in the back of my mind, so it didn't really change the way I fly. Flying in the mountains all the time, there are many times when there are no good options. Night time in the mountains is even worse. There are no good options. I put a lot of my effort and money into making sure that I don't see another engine failure. I can't eliminate all risk, but I can sure reduce it by making sure my powerplant and fuel systems are in first class flying condition. Jeff Scott Los Alamos, NM N1213W -- J Lwrote: I think a good scare is in order every once in a while. I have never flown the same after I had my engine quite because of a factory caused mag failure on my VW. Had it quit one other time doing a high speed flyby and pulling to 45 degrees and then banking 90 (uncovered the fuel supply hole). That was stupid on my part. Luckily it started again by windmilling as I have no starter. The mag problem happened over the airport. Mark and Mark, you guys have nerves of steel to have snapped back from engine failures as fast as you have. I am always looking for a place to land from takeoff to touchdown. You just never know when it could happen. Its been 3 year since the last incident and I still can't get it out of my mind.

Gary, I learned how to fly off of a winch tow. I haven't ever seen one set up in the US. I recently moved to the seattle area, do you know if there are any clubs using winches around there?

Food for thought: While it's been many years since I flew a single engine helicopter, as I recall it took about 12 - 15 seconds to get on the ground from 500-700 feet AGL. Of course if you fail to respond correctly and manage your rotor speed you will fall faster. Also, when your engine quits, you look through the chin bubble and that's where you are going to land. 38 seconds is an eternity.

I'll always remember what my instructor said to me when I became a bit stressed after the engine actually died when he cut the throttle at 300 ft during takeoff on a flight test. He said "come on, you've flown out of here plenty of times, you should know where you're going to put it down". The choices at that airstrip weren't wonderful, but I realised he was absolutely right - for most flights that's one decision that should already be made in the event you suddenly find yourself in a glider. The only exception I can see is if it's an airfield you've never seen from the air - and even then you could (probably should) usually ask someone with local knowledge what the best option is before you start the engine. Fortunately, while he was telling me I should know where to go my instructor was also on the starter button and got the engine restarted so we didn't have to put it down in a swamp. I concentrated on achieving and maintaining best glide speed then turning towards the least treed area. I must have done OK because he passed me, but I learned an important lesson that day. Always be prepared for an engine failure and review your options frequently.

KR> engine out update
Guys I think that I have done and checked every thing that I can imagine and all the stuff that you guys thought up. I ran for another half an hour tonight. Every thing just seemed so sweet. I have been working hard at being precise with set up. The gaps, dwell, and timing as well as fine tuning the aero carb a bit. As a result right now I have the 3100 running as smooth as it ever was. Acceleration is smooth quick and responsive. It has gained a full 100 rpm at take off speed over what I have had the past several months. I am going to fly it in the morning- I could have tonight but just wanted one more night to mull the whole thing over. I know it has nothing to do with it but maybe I'll check the air in the tires just incase. Who ever has that Voodoo doll of my plane please put it away now. Thanks for all the help, Joe Horton, Coopersburg, Pa. joe.kr2s.buil...@juno.com
KR> engine out
Guys, The short and sweet of it is that I have gone over and checked every piece of engine, fuel and ignition. Reassembled with all the same parts. It started right up. Flipped back and forth between the 2 ignitions and no problem found. I ran it for about 20 min last night. I will replace everything on ignition #2 tonight (condenser, points, wire, and coil) the other change that I am going to make is in the ignition switching to a switch that instead of being on #1 or #2 is a switch that will be #1- both- #2. This would allow both for take off and landing. Any and all comments Joe Horton, Coopersburg, PA. joe.kr2s.buil...@juno.com

Joe did you have it running for a long time static ( idling ) on the ground before take off. Before I directed a blast tube at the gasolater early on which corrected the engine cutting out after landing and a long taxi on a hot day. What would happen is after landing the engine temps would come back up and when I applied throttle to speed up the taxi it would burp fart and carry on, after the blast tube that was no longer an issue. This was only an issue on the hottest of days 90 and above. Kenny - Original Message - From: "Joseph H.

Hey Joe - good to hear the engine ran fine. My guesstrash in the points or maybe a hot coil - next tiem (hopefully not) check your secondary coil. On testing I once had the A side not work and found dirt on the points - cleaned them and was back in business. Fly light the first few times (better climb and all that) and plan emergency landing procedure to get confidence back in your system. I have no doubt youll be fine. Bill
