Christmas coming and being from the Northern USA, he and the family cut themselves a purty Christmas pine for a Christmas tree in their home. Took it in the living room and set it up with lights, etc. Really beautiful he said. Next day the house was full of bugs; big bugs, little bugs, muskeetoes, biters, crawlers, everything. A big mess. Seems that all those critters nest in them there pines during the winter and they thought they woke up in the bahamas or something. I guess you should check with the natives before you take up a tradition in a strange place.

I live about 30 miles from Filton and I remember the Vulcan that had its bomb bay fitted out as a test bed for the Concorde engines growling around the sky locally. I was on the beach near Weston super Mare as Concorde banked at the end of her final fly by circuit before landing at Filton for the last time. There was not a dry eye in house, she was soo beautiful and we shall not see her like again.A sad end to a marvellous chapter in aviation. Thankfully I was lucky enough to fly in her 3 times. Once to Egypt, FOR THE DAY, how cool is that, and twice to the States. The cheer that went up as the Machmeter on the bulkhead in the cabin clicked up Mach 1 and then Mach 2.

I don't know why that seems hard to believe, grease is an excellent, think corrosion preventative that is thick and does not evaporate over time like many of the light oils do. If you have doubts as to if it works or not, try it on one elevator half pivot bolt, or other high wear area, and leave the other side dry, and compare your results after the next 100 hours.

Would have to look it up in the parts book. They seem to fail with extended time, or did back in my day. Another reason for not wanting to idle normally, is an engine that is not operated normally. If you only run it on the ground, never going full power or cruise power, the engine (crank case) with load up with excess oil. Causes irratic/poor running and a lot of blue smoke. If you are running rich at idle, it should probably blow black smoke. I'm not too good at two strokes any more. Hardly ever operate one except my chain saw and weed eater.

I never actually pulled the bolts on mine (I hope Bob does at some point), but I did at one point pull the joint apart to troubleshoot the little bit of slop at the channel bracket where it bolts to the frame. That whole joint is well designed (IMO), but is fairly low tech. It doesn't have to be high-tech because it's not a high speed or constantly moving joint, but it can eventually start to wear if you fold the wings a lot. If the bolts are that worn I'd also check for slop at that channel bracket, as if it gets too bad it can change the AoA of the wing panel slightly. The original builder of my plane used shims of some kind under the channel bracket to tighten it up (he folded it all the time too). I'd treat the bolts and the channel brackets as consumables if I folded every flight (i.e. I'd have spares on hand and would replace on a regular basis)....

FS 447 > [b] Most likely the idle jet is plugged. this happens over time easily on the bing especially on the 2 stroke if you let it sit for long periods of time. This blocks off the airflow through the jet and makes the thing run full rich at idle no matter how much you open the idle mix adjust screw. If the choke weren't sealing right you'd have a more extreme version of that, up to and including 4-stroking or even 6, 8, 10 or more -stroking as you approached full throttle....... Don't ask me why I know that...... Pull the choke plunger and check the rubber stopper at the bottom. If it's really hard or chewed up replace it. Just an impression on the surface is ok. Check the action of the choke and make sure the plunger seats fully by itself when you close it with the lever. I.e. press on top of the plunger.... Any drag in the choke system can cause it to hang open a little bit, which can be a BIG eye opener on takeoff....

The amount of wear from folding (1/4 revolution each fold) is probably insignificant compared to wear from vibration and changing flight loads, unless something is way too tight or binding badly. OTOH, the looseness required for folding allows more motion (and thus wear) than tight bolts. -Dana -- A cement mixer collided with a prison van on the highway.

How's the rebuild going? You going to be ready to fly it this year? -Dana -- A cement mixer collided with a prison van on the highway.

Yes, even with powder coating, the rest of the airplane requires some attention. There are some areas where I have had to remove the powder coating where it gets chipped, or for whatever reason has not sealed well, and sand off the corrosion and use Epoxy Primer. Corrosion X helps with the inside of the boom tube, and I will be putting Corrosion X it in the wing spars for the first time soon. Fortunately, I am in an enclosed hanger which helps a lot.

Changing from 70". Test flight yielded 5400 rpm WOT straight and level flight. I knew it was going to be a tad over pitched before I took off. Was looking for 5500 to 5600. Flew great, even though not quite as brisk as I like it. Today, pulled 1 degree of pitch out of the blades. Used the Warp Drive Protractor to do that on one blade. Then adjusted the other two blades with a laser tool provided by Scott (icrash). It worked great to get all three blades reading off the same sheet of music. My field elevation is 410 msl. Pulled 5400 rpm climbing out. Engine felt brisk. Climbed to 5,000 feet msl. At 5,000 feet the 912ULS was turning 5,300 rpm, climbing a steady 1,500 fpm with me (200 lbs) and 15 gals (90 lbs) of fuel, at 45 mph indicated. OAT was 40F at 5,000 feet. WOT straight and level at 1500 feet yielded 5,600 rpm. I am happy. The engine and airplane seems much lighter when freed up a bit, rather than overpropped. Cruise seems to be about the same, 80 to 85 mph, at 5,000 to 5,100 rpm. Now, when I head out West, I'll have a good responsive combination to haul a lot heavier airplane at much higher altitudes. Did not experience any abnormal operation with the new blades, as usual. john h mkIII ________________________________ Message 33 ____________________________________ Time: 07:19:18 PM PST US Subject: Kolb-List: Re: Wandering Wench is on her way From: "John Bickham" Yep, that me! We "passed a good time". It was great meeting and visiting with Arty (she hates "ma'm") and Randy. Also got to meet another Drifter pilot from Beaumont, TX - Tom Harlagn (sp?). Arty has taught me something new about XC flying. You don't have to worry about those rough air mid-day landings if you don't take-off till afternoon. Seriously, they left Nauga and False River late mostly because she needed to catch up some much needed rest. She is a tough little thing and pretty amazing to watch stuck out there on the front of the Drifter. When you guys catch up with her at Sun-n-Fun, she is getting real close to getting a Kolb. Those Drifter's eat a lot of runway both in and out. Had a great visit, hope they did too. It was some great weather while they were here. Rained 5" in 2 hours Sunday. Nauga Field had a water retention issue. -------- Thanks too much, John Bickham Mark III-C w/ 912UL St. Francisville, LA Landing a plane and being married - a few smooth moments mixed with a lot of rough ones.

I thought you could only get them in evens.... Even with the mild problems with harmonics on my plane, my WD continues to shock and amaze me with its performance. My 68" still gives me around 1000fpm at my field elevation of 6300' and yet yeilds right at 100mph indicated at only about 5100 rpm slightly above half throttle. I may have posted this already but I did also discover the other day that the harmonic part of the vibration goes virtually away at cruise, so I may be able to keep the WD on the plane as-is. Dennis and I if all goes well with weather (and I get my leave from work) will be travelling to MV a bit slower than that tho, as his Mark III is about a 70mph airplane (reminiscent of my FSII). I'll have some kind of prop on the airplane anyway whichever one works out to be the smoothest....

Asked me if I would like a set of his titanium tie downs. Replied with an afirmative. A couple days before I took off my tie downs arrived. I am very proud of them and take them with me every flight. They are limited in rocky soil, like out West. I also have some home made tie downs, rebar with a chain link welded just below the top, to use in rocky areas. Can pound them in with a mallet, rock, hachet, or whatever. Also have some nice long 3/8" braided nylon rope. Nothing like landing in a wind storm only to find the tie downs are spaced to far apart for your ropes. john h mkIII ________________________________ Message 37 ____________________________________ Time: 07:54:19 PM PST US From: "John Hauck" Subject: Re: Kolb-List: Re: Tweaking the Warp Drive > Can you get blades from WD in odd lengths?

They'll cut them any length you want, up to 72" (I think that is their max length with nickle edges). 75% power is right at 5000 to 5100 rpm on a 912. A little more than 1/2 throttle. Throttle lever positions are not good indicators of power the engine is producing. RPM works better. I have a slight vibration at 5,000 rpm with these new blades pitched the way they are now. I like the pitch, so I'll probably cruise at 5,100 or higher. Every engine has a sweet spot where it is happiest/smoothest. That is where I like to operate. If, for some reason you find a vibration, use the throttle to find a better place. Even turbine engines have certain speeds that one should not operate because of bad vibes. Doubt you will find an airplane engine of any type that is absolutely vibrationless through the rpm range. john h mkIII ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message kolb-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Kolb-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/kolb-list Browse Digests http://www.matronics.com/digest/kolb-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
