Have been holding right rudder...just a bit... to keep it straight at 50 mphi and about...not sure, but about ... 5300 rpms. Decided to try "feet off" and got slight nose pitch up and what felt like a slight flutter somewhere behind me. Can't see what's going on back there. Not reassuring, though. Back to pedals and okay again, but holding a bit to keep it straight and flutter disappeared. Did it twice. Air calm, conditions ideal. The huge rudder trim tab (12" tall and 6 3/4" wide at bottom, bent about 15 or so degrees to right as you face the cockpit, and riveted 22" down from top on the trailing edge pipe of the rudder), was sloppy, loose. Drilled the aluminums and the one steel rivet wasn't attached anyway, intending to find a better way to attach the tab to the round pipe surface. A&P said it you are having to hold right rudder, you are already fighting that trim tab.. "Try flying it without it." Think I read one of the Kolber gurus said you gottas have em, nature of the beast and all that. I'd like some solid information about this idea before I play test pilot again. Ideas? Wouldn't mind flying tomorrow. Some haze with the moisture, but good conditions in a.m. Still a bit of oil spray on prop, apparently from behind the front carb on the 532. Just replaced the gaskets at about 95 buck s a whack each and think I have em tight. Oil appears to be from one of the little mystery hoses there. Again, open to ideas of getting this thing good to go. Did replace the muffler gaskets, and didn't put any sealant on them. Ones I removed that were really leaking looked okay. Wondering if there is slight warp that may have occurred in past. Anyway, always grateful for the help and the array of ideas. jsf ________________________________ Message 4 _____________________________________ Time: 12:24:38 PM PST US Subject: Kolb-List: Re: rectifying problems maybe From: "George Alexander" --> Kolb-List message posted by: "George Alexander" jsflan(at)valornet.com wrote: > > Have been holding right rudder...just a bit... > > The huge rudder trim tab (12" tall and 6 3/4" wide at bottom, bent about 15 or so degrees to right as you face the cockpit, and riveted 22" down from top on the trailing edge pipe of the rudder) > Not sure from whom/where I got the recommendation for attaching the fixed trim tab, (CRS) but I do remember that it was from a respected source. Mine spans the bottom two ribs in the rudder (not the bottom edge). This puts the vertical center of the trim tab at about the horiz stab. In the construction of the rudder, the ribs are bent at the rudder trailing edge into 'L' shape, then riveted to the TE. The rudder trim tab was made of sufficient size to be able to rivet it to the ribs a couple of inches forward of the TE and in the 'L' where it connects to the TE. I did not rivet it to the TE. Have attached a picture of the rudder showing the approximate set up for the trim tab and where it is riveted. The blue lines are the rudder ribs and the dots show the rivets. (The picture was actually taken before the trim tab was installed. I have modified the image to show the approximate setup.) jsflan(at)valornet.com wrote: > A&P said it you are having to hold right rudder, you are already fighting that trim tab.. > > Would agree with your A&P re: fighting the rudder.

Check carb alignment to ensure that they are level particularly if you have had the carbs off replacing "gaskets". Just some things to consider.

If you do not have strong return springs on your pedals then you can expect the rudder to flutter if you remove your feet. In my case, there are no springs, instead there is a return cable loop. It works well but if you take your feet off the pedals you can expect a flutter to start soon. Also, when Bryan Melborn builds Fireflys he always puts the same tab on the rudder from the get go.

I'll read a while longer. Maybe ask for some more specifics. Such as, my being new to Kolbs, haven't sorted out Bryon or what his standard tab is. Or if it is suitable to the Mark III.

Not just a slight flutter, more like "Your boom tube is now a sine wave" and the rudder pedals are moving to the stops in both directions flutter. Some rudder flutter is fairly common for Kolbs, but mine was absurd. And probably very bad for the airframe...

For a while I thought you might beat me into the air, but now I have hope again!! A few thoughts: 1) I have the SPG & it is a bullet proof unit with a BMW rubber donut, rated for 150hp. It would be a great match for you if only a VW adapter was offered. the north america dealer told me a guy in CA made a VW adapter & it was just a flat plate. He could probably get you the guys name. The rotax e-box might be the best way as it incorporates a starter & that might save you a lot of weight, but they won't sell you one unless you provice a serial # of your rotax engine. 2) About wiggles: All inline 3 cyl (2 or 4 stroke) rotate around the axis of the crank. Nothing will stop it but a counter rotating shaft. All 4 cyl inlines jump up & down & only a counter rotating shaft stops that. the flat opposed 4 is inherantly cancelled & is the smoothest configuraton. The wiggles from the inline 3 & 4's are obviously sufficiently delt with in thousands of instances or they wouldn't be seen in aviation. Everything is a compromise! 3) Please don't give up!!!! You are a hero to many of us. Progress Report: After coming up with a 42% cg I had to drop back & start afreh. I moved the engine 12" forward which caused me to weld up a new oilpan & oil pickup. That's done. Now the engine sat too high so I cut out the engine mount & backbone which left a bigggg hole to drop the engine (3cyl, Suzuki, 100hp, turbo, intercooled, distributorless ignition, port injected, 107 lbs torque at 3600 rpm) into my SlingShot. I bought a tig welder & wish I had done so years ago. It is so easy & does such a beautiful job & no sparks to fly! After just messing with the oil pan, I am confident to start on the kolbs structure. that's not done yet. I keep changing the design & am going in circles. Its hard to keep it simple, light & strong--- Kolb is a genius at that! I will prevail. Looking forward to another visit when you pass this way. -richard swiderski Read this topic online here: http://forums.matronics.com/viewtopic.php?p=65632#65632 ________________________________ Message 16 ____________________________________ Time: 07:46:19 PM PST US Subject: Kolb-List: [ Mickey Morgan ] : New Email List Photo Share Available!

Steve FireFly 007 on Floats ________________________________ Message 18 ____________________________________ Time: 08:23:51 PM PST US From: "Larry Cottrell" Subject: Kolb-List: EIS Just a bit of useful information regarding EIS and capacitance senders. I bought a new EIS model 2000 for 2 stroke engines when I began the rebuild on my Firestar. The main reason that I went with the EIS is that the new pod from TNK is shaped different, longer and more streamlined, and my analog gages were not going in there like I would have liked. Plus I had intended to use a 503 motor with dual EGT and CHT senders. My gages were for only one of each. So for me the cost was worth it. Plus when I talked with the gal at Grand Rapids Tech she informed me that I could get a remote to do the changes in the display rather than have to lean forward or as Ralph said, carry a big stick. So I got a stick grip with five buttons on it, which I configured to the EIS. Works great! Then Boyd tells me that he is using his EIS to monitor his fuel. So I talk to the gal at GRT and she walks me through the set up for the fuel. Last year my fuel gages had quit reading my fuel levels. I "thought" that it was the senders that had malfunctioned, so I bought two new ones @ $95 each. They didn't work at all, so it was going to be the gages that needed to be replaced this time. I really did not like that set up because I had to run the fuel lines to a selector valve up to the front where I could monitor them. That is quite a long run, requiring a facet fuel pump to make sure that the gas got back up to the motor. Now the way that it is set up is that both tanks are plumbed together, with the facet pump next in line then through a "Heffner" gascolater to a filter then to the pulse pump and the engine. The EIS AUX line reads the capacitance sender and at full (10gal) shows 56 on my display. 8 gals is 50, 6 is 35, 4 is 20 and 2 gals is 6. I have the alarm set to go off at 9 which means that I have 3 gal of usable gas. I took the top of tank pickup tubes out and installed a weighted filter on the ends of the pickup tubes via some fuel line. This is so that I use all the gas that I have available. I had previously raised the tubes up off the bottom just as a precaution to prevent picking up any water or garbage that might have accumulated on the bottom of the tanks. With the gascolator I can drain all that out and it will not be a factor. I did not realize that the EIS would do this when I bought it. Thanks Boyd! One of the factors that cause me the greatest unease when I fly here is how much fuel I have. Every place can be hazardous to landing here, and it is a looooooooooong way to more fuel. Larry, Or
