Sunny, 60's, light winds, probably the last good day... >> Hi Dana, I took my plane out of the air for the winter about 10 days ago. It was a lovely day but cold winds and rain were forecast. After all it is nearly the end of November, much late than usual and I have had enough unscrewing nuts and bolts with freezing fingers so I took the decision. Every day since has been flyable with little or no wind, it has not been cold yet and it has been sunny.( My new solar panels have generated 40 Kw in this period) You just have to call `em like you see `em and make a decision. I was wrong.

During primary training I was trained to keep the ball centered at all times especially in stall. In less I'm miss interpreting your description I have to believe you were allowing the plane with the trim tab to yaw when going into stall. I currently have the leading edge of my vertical stabilizer off set by about an inch. I really couldn't tell any difference but it has to help the trim tab do its work. My trim tab is defected about 45 degrees and seems to be about right. I add left rudder under full power climb, right rudder power off and just a bit left in cruise. Big high thrust props flying at a high angles of attack produce lots of asymmetrical thrust referred to a P factor. No thrust, no P factor. Your photo was taken from one side so it will naturally look like it is defected. Rick Neilsen Redrive VW Powered MKIIIC On Wed, Nov 16, 2011 at 9:35 AM, Richard Girard wrote: > Thanks, John.

I know it ain't fancy and glamorous but I used the full synthetic 2 cycle oil from Walmart in my recent Cuyana adventure, and it was very smooth running and no plug fouling and inexpensive. Still have plenty left I was using it in 40 to 1 if I remember it right. Back in my Yamaha motorcycle 2 stroke days I used whatever cheap 2 cycle oil I could find mostly because I had no idea about one oil from another. Sometime in the 70's I switched over to synthetic oil and was surprised at the lack of smoke and the improved smoothness. Nowadays when the occasion arises I use only 2 stroke synthetic lube and am happy with it. I need to add I never had a 2 cycle motor failure,, ever!!!! I think the Walmart brand is called Super Tech oil, I doubt we would find anything better at 3 times the price, and its probably down the street from all of us, excluding Pat; poor fellow no Walmart in Britannia.

I'd recommend flying a Kolb first. Then...if it doesn't fly like you think it should fly...change it to your satisfaction. Kolbs have been flying for many, many safe, enjoyable hours, as they were designed by Homer Kolb and Dennis Souder. I made changes on my Kolbs based on flight experience in that particular model. My first Kolb was an Ultrastar. The only changes I made to it were progressively heavier wall tubing for its rigid landing gear, because, at times, I blew landings, usually landing on one gear leg and bending it. The Firestar, we went to heat treated 4130 gear legs much longer than stock gear legs. This put the FS in a good 3 point position for taking off and landing. Also helped some to keep it off its nose. and helped me get it slowed down on my 600 foot airstrip because I had no brakes. BTW: I made a flight in the FS in 1988, with no brakes, from Alabama to Monterey, NY, to the Flight Farm. Had no problems, but had to stay well ahead of the FS in all taxi situations, especially when the fuel pumps were at the bottom of a slope. When that happened, I'd get out and walk the FS to the pump. We made changes to the MKIII based on 1185.0 hours flying the US and FS, and what we needed to make extended cross country flights. Based on flight experience in the new factory MKIII, I decided to reduce the size of the ailerons and flaps. The easy way to do that was snap a line from the stock inboard aft corner of the flap to a point a few inches short of the stock aileron aft outboard corner. This way I reduced more aileron and lost less flap area. Putting more weight on the tail wheel by moving the main gear forward was insurance during off field landings to keep the mkIII off its nose. Other than tuning horizontal stabilizer leading edge positions, I never changed any of Homer's flying surfaces. With more than 3,100.0 flight hours and nearly 20 years, my mkIII and the few changes we made to satisfy me, have worked out well. I see nothing wrong with wanting a V tail Kolb and nose gear. What it will accomplish to make it a better airplane than the stock configuration, I have no idea, other than to satisfy the builder/flyer. I still think it is a good idea to fly your airplane a significant amount of time before you decide it needs changing. You may find that it is a great little airplane in its stock configuration. john h mkIII Titus, Alabama - On a rainy Sunday morning. ________________________________ Message 8 _____________________________________ Time: 09:01:51 AM PST US From: "Ron @ KFHU" Subject: Re: Kolb-List: Some success at last Yup !!! ---- Pat Ladd wrote: ============ John, your post is coming through too large to fit on the scheme, large font and blue in colour..

If the nose of the airplane is pointed at 45 degrees the airplane does not climb at 45, it climbs at 8 degrees or so (I am sawgging) so the relative wind is not impacting the blades straight on. Its impacting the blades from say 37 degrees. So the blade coming down hits the oncoming air at 37+whatever angle it has, and the ascending blade is climbing at 37- whatever angle your blades are dialed in for. Make sense? Ron @ KFHU ================ ---- Pat Ladd wrote: ============ <> Thanks Dana, Humm!. Not completely happy with that. If you have enough power to climb and NOT slow up, what happens then? As far as I can see the airflow direction in relation to the plane (what in sailing circles is called the apparent wind) is still directly on the nose. In that case it would appear that it is a matter of airspeed, not attitude. Therefore the P factor should change as you throttle back in the cruise. Does it?

With the Kolb in level flight, the wing will be at an angle of attack somewhere between 5 and 10 degrees, depending on airspeed, trim and any number of variables, but in any event, it will be at some angle of attack relative to the airflow in level flight. Engine mounting typically has the engine adjusted so that the prop is perpendicular or at 90 degrees to the airflow at level flight. Some have tinkered, for varying reasons with varying results, but just for the sake of argument, let's say that 90 degrees is probably typical. The airflow as it departs the aft section of the wing into the prop will not be at 90 degrees relative to the prop, even though the prop might be mounted 90 degrees relative to straight and level flight, because the airflow coming off that wing is going to be descending for several feet before it returns to being true relative wind and regains it's normal horizontal, or undisturbed flow. This descending angle could be further compounded by the airflow coming off the top of the wing within that prop area - or maybe not, depending on how bad the engine messes it up. In any event, you have a downward vector of airflow for several feet behind the wing, and that is what the prop is slicing through. I went out to the hangar and turned the 2 blade prop horizontal and looked at it from one side to see it's apparent angle of attack to the visualized descending airflow off the wing, and then went around and looked at it from the other side. The downward moving blade would be slicing through the airflow off the wing at almost zero angle of attack, while the upward moving blade will be going through that air at a very large angle of attack. Since I am running a 582, then the right blade effectively has a very fine pitch, while the left blade will have a comparatively coarse pitch, biting out a bigger hunk. Bearing in mind that the prop center line is several inches above the trailing edge of the wing, this is not a clear cut situation by any means, the descending blade is starting to sweep down and left, the ascending blade is going up and left through the wing-redirected airflow, but it will still be true to an extent. Which means that the lower left side of the prop is pushing harder than the lower right side with the net effect being that it will push the nose to the right. Which agrees with me needing a trim tab sticking out the right side of the rudder, to push the rudder left, to push the nose left, to counteract the left side of the prop pushing harder. If you had a 4-stroke Rotax, then the rudder tab needs to go on the other side, for all the same reasons. If it were possible to modify the Kolb center section so that the airflow just ahead of the prop was not receiving a downward vector, then (if this theory is correct) the need for a rudder trim tab would pretty much go away. This is just a theory, and like all theories, I have probably overlooked something.

A tractor engine mount gives the propeller clean air as apposed to trashy air flow entering the pusher propeller. That is why it so important to trim the wings level and then start washering the engine to move the ball or string slip indicator toward the center. At some point you will not be able to gain additional improvement from further washering and then you must tab the rudder to remove the remaining slip. You can only get it right for one desired aircraft loading and cruise speed while in level flight. For all other cases, slip and power factor will creep back in. With the ultrastar, firestars, kobras and the firefly it is a little easier, because wing loading due to fuel, pilot and passenger is symmetrical. But with the mark III's this will not be the case if one trims out for single seat flying. It seems that if one trimed out for this condition, a different aileron and rudder trim would be required when piloting from the right or left seat. And again it seem like it would be different when carrying a passenger. Have you noticed that is the case with your aircraft? Jack B.

My trim tab on the right aileron is adjustable, and I set it different when I am solo vs carrying a passenger. -------- Richard Pike Kolb MKIII N420P (420ldPoops) richard (at) bcchapel(dot)org Kingsport, TN 3TN0 Now faith is the substance of things hoped for, the evidence of things not seen.
