    From: "grantr" <grant_richardson25@yahoo.com>
    I guess I am hard headed but I always wind up going out to fly in mid day conditions. I hate getting up early and I hate going out late and getting home late especially with the time change having it get dark around 8 so I choose to fly in mid day conditions. I don't know how rough it is in larger planes but it sure gives me a workout keeping the wings level and the airspeed and altitude constant. The winds were not bad at 5 to 10mph but thermals were! Its fun though and I can climb over it. It has helped me flying in these conditions to become more comfortable with the airplane. The rough air still makes me a little nervous at times especially low on final when I get a good toss. I have posted 21 videos! WOW I didnt realize I was enjoying this camera so much.:D http://www.youtube.com/watch?v=i83zmWxqpZM&fmt=18 http://www.youtube.com/watch?v=3Gvs3PaElJM&fmt=18 Read this topic online here: http://forums.matronics.com/viewtopic.php?p=236075#236075

    That kind of air brings up my only complaint regarding my Kolb. Strong up/down drafts involve what I consider to be excessive pitch changes and corrections. Whether it is a symptom of only my individual airplane is open to question. I would prefer that the result of a sudden boost from below would involve less noticeable speed and pitch changes. Wing leveling corrections are understandable and are common to all craft but watching the ASI go from 40 to 80 in a matter of seconds is not comfortable.

    Hi, I used Marvel in the fuel of British sports cars in the '70's. Seemed to prevent sticking valves, didn't seem to hurt. I use their Air Tool oil as an after-run oil on RC 2-strokes, works great.

My own understanding from earlier articles on the subject is that Marvel Mystery Oil is a light viscosity oil, roughly equivalent to an SAE 3W, containing (among other things) about 20 percent solvent (probably mineral spirits), dye, wintergreen for smell, and 790 PPM of a phosphorous additive.

Might be that unconventional power plant. ;-) Seriously, and I'll try my best to be, that is not a common problem with Kolb aircraft, of any model, that I am aware of. I don't like rough air either, but in most cases, if you are going to get where you are going, ya gotta fly... John W and I had a unwritten law of anything over 25 mph ground speed was reason for staying on the ground. We demonstrated that May 2008, when we spent three days waiting for the wind to subside at Ontario, OR. The wind averaged about 45 mph for all three days and nights. Got used to walking around at odd angles. john h mkIII

    I am guilty of flying too low also. 25 mph wind over the flatlands is fine. When the terrain is bumpy it's time to climb. The lumpiest part of most of my rides is when I descend to the rolling hillsides returning to my home strip.

The last time I flew my FSII in midday thermals was one hot day back in TX and that was indeed the last time I ever did that. The titan has significantly higher limits in stuff like that, but even then I prefer not to battle airmasses that are trying to slam the plane into the ground while I'm trying to land. The trip back here to NM from nebraska, I ran into the midday stuff over Kansas, as that was about 1 or 2 in the afternoon when I was out in that particular area. I had it slowed down to 90 and even 85mph, and I was still getting popped up into the shoulder straps from time to time. I've just accepted over the years that I don't like flying on the edge of control. Regular full-stop control movements just to maintain flight or keep the plane out of the dirt isn't a region I like to be in. I'm ok being a wuss nowadays. but in good smooth air, there wasn't a much more fun plane to climb into than my FSII. Even after I'd bought the titan and before I had to sell er, I was usually in the FSII in late afternoons shooting wheel landings or sightseeing rather than the other plane. I can tell I'm pining away for that plane a bit. The firefly idea keeps coming back too...

    I hate being throw up in the shoulder harness! I hate roller coasters and thats what it feels like when the negative Gs occur! :( My asi didn't fluctuate much over 10mph and the fluctuations were mostly positive gaining asi. Strong up/down drafts do not seem to be that big of an issue in my plane. There are times when I have to be aggressive with fore or aft stick to overcome a vertical gust but for the most part I only make minor pitch changes to maintain a stable pitch attitude. I did have a lot of horizontal gust which was causing my plane to yaw around a bit. You can see it happen alot in the videos. Just the ole girl wagging her tail. [Wink] I guess thats just a matter of where you are in relationship to the up or down draft as to how it affects the airplane's axes Read this topic online here: http://forums.matronics.com/viewtopic.php?p=236121#236121

    FYI The Ellsworth Air Force base at Rapid City SD is allowing civilians to fly in on May 23 &24 of the Memorial Day weekend. All you need is a radio. Arrival is morning. There will be lots of exhibits and the Thunderbirds will put on a show. You do need to submita waiver tothe AirForce releasing them ofresponsibility.Complete details are not yet finalized but you can get information from EAA39.org site.

With the original ailerons, the FireFly could not be controlled in roll. One had to kick rudder to help lift a wing and so flying mid day was an exercise in dutch rolls. I found that I could not tolerate an hour or so of dutch rolls and so mounted nine inch chord ailerons. They were wonderful. With them the FireFly may bob up and down a little, but with light stick side pressure, one could keep the wings level. It made mid day flying very tolerable with out worrying about up chucking. I have continued to fly at mid day as it is more interesting. If I am going somewhere, I climb to at least 2,000 feet and mostly to 3,000 feet agl. There I discovered the thermal and winter weather rolls are greatly abated. By doing this there is only five to ten minutes of very active air that has to be tolerated climbing up or gliding down. The only time I do not feel comfortable in the FireFly is if I do not have my shoulder straps snug. If I can feel my back coming off the sling seat back, I get uncomfortable. During turbulent flight, if I do not move relative the FireFly, I am ok. Weird things will happen, but a bit of pressure on the stick and/or rudder usually set thing right. One of the advantages of flying mid day with the thermals, is that you can pick up about five mph ground speed by following a thermal street. Jack B. Hart FF004 Winchester, IN

    I have flown my MK III Xtra through mid day thermals, and it has never been a problem in pitch. The MK III Xtra has very good control in pitch and have only needed small fore and aft stick pressures to maintain level flight. I have never ever even come close to using just half stick for pitch control in turbulence. Roll control in my Kolb was to slow for me, I have never had to use rudder to get the airplane to roll level in turbulence, but it was slower than I liked so I added the Aileron Spades. With the addition of aileron spades on my Kolb, it is very controllable in roll, but being used to flying airplanes with very responsive ailerons, I am hoping to get a little better roll rate and lighter roll forces with my wingtip mod which will keep any wingtip vortices off the ailerons. Time will tell when I do this project. Remember when flying in thermals, its not just air rising and sinking, the air is swirling and moving all over the place in horizontal directions as well as vertical, so some yaw and other weird movements will happen. I never see changes in airspeed over 10 MPH in turbulence though. Gusts of 40 MPH are reason not believe the airspeed indicator though, that kind of air movement would result in severe turbulence even in a heavy jet, and would make a light airplane unflyable, and is very very rare unless in a thunderstorm or other extreme and rare condition. Heavier airplanes tend not to get thrown around so much in turbulence, and the airfoil also has a big effect on this. As John H says, the flat bottom Kolb wing loves to lift, and if there is a vertical gust, it will lift the heck out of the plane immediately, more so than other wings ! With a very high lift, slow speed wing, feeling the bumps comes with the territory. I like flying in the mornings and evenings, I don't fly mid day unless I need to go somewhere. Funny thing is my wife actually likes the turbulence, I can let her fly in the worst mid day stuff I can find and she says she wants more. One day I told her that is she likes turbulence so much that she should fly under one of the many thunderstorms we have here in South Florida. She said she would like to but had doubts as to weather the plane could handle it ! Here are some pictures flying in some convection induced turbulence, if you notice the airspeed, I do slow down for turbulence, it helps :) Mike -------- &quot;NO FEAR&quot; - If you have no fear you did not go as fast as you could have !!!
