I have a buddy that built a 601 xlb and it used the top skin of the aileron for the hinge.  That seemed a little different to me. He has had no problems in over 200hrs.   I guess I am just trying to reinvent the wheel when it comes to the flaperons, probably not worth the time and effort.

Ed,
 sorry I didn't give you my location . I live in south central Pennsylvania. Near Gettysburg. I fly out of Lazy B Airport in Dover PA.
 
Thanks, Cliff

Ed,
Yea and the Wright Brothers used wing warping but you don't see that on any new designs. I  had just been day dreaming about how to improve the stol performance of the avid and came up with this idea. I watch the  stol planes with the huge flaps, Sherpa, supercubs, Highlander, and alike. They all have seperate flaps and ailerons. What got me to thinking about the yaw was, I had a Taylorcraft 15a a couple of years ago and when I got it, it was out of rig. We attempted to make it fly straighter by tweeking first the ailerons then the flaps. During the changes we actually induced some  yaw with a flap adjustment. I never did get the thing to fly perfectly hands off before selling it. It just made me realize that ailerons  at the root of the wing don't seem to make much sense. I know that Avids and Kitfox have been flying for years, I just don't like the set up. I was just trying to see if any one actually flew one with the split  set up to see if it is worth all the extra work.
Thanks, Cliff

Ed,
 
Thanks for the info. It will be another year until I get to the mark 4. When you get your design finished I would be very interested to see it. Hopfully you will have yours finished and flying by then. Have you ever heard of it being done before? In my opinion the flaperon set up was a compromise to make the folding wing easier to engineer. Giving up better flight characteristics for simplicity of design. I am not a flight engineer or an expert in design. I have just looked at all the other airplanes that I have flown and none had flaperons and non lost alieron throw with the flaps down. Thanks again, Cliff

You are doing exactly what I had in my mind. I was going to mention the crosswind landing improvement in my last post but my wife asked me to do something with her so I cut it short. I also thought that if the flap cord was increased and balanced correctly you could have them almost touch the trailing edge of the wing when fully deployed for better flap athourity. If you have any pictures of your modification please post. One of my projects is a mark 4 with speed wings, I bought a wing extension kit from airdale and thought that when I rebuild the wings I might use a split flapreon design. I also need to install a left speed wing fuel tank at rebuild time.. I just haven't had any time to work on the Avids lately. I am still in the middle of a cosmetic (paint and interior) on my cessna 206. It is taking way too long to get it finished. I have an A model that I have put Kitfox 3 wings on that is very close to being finished, I plan to get it flying next then start back on the mark 4 next winter.

I only have a few hours in an avid heavy hauler so this is just what I noticed while flying it. The ailerons become less effective whith the flaps down and not because of lower airspeed. There is actually less aileron throw  with the flaps down. My thinking is that if you split the flaperon into 2 sections you might  have more aileron control at lower speeds. It might be necessary to make the aileron and flap have a little longer cord. It might help with adverse yaw also. I was just thinking about it and wanted to see if anybody ever did it. I know if it aint broke don't fix it , I was just wondering.

Snaps,
  Does your left damaged speedwing have a tank in it that you would consider removing and selling? I only need the left tank and fuel cap. If not does anybody have a left speedwing tank for sale?
 
Thanks, Cliff

I am knee deep in painting my 206 right now. As soon as I get that finished I will be ready to get to work on the Avid's again. I am browsing the threads right now to see what has all ready been discussed. I don't know how to down load pictures, I have just enough computer skills to be dangerous. I plan to learn more.  Thanks again for the tips, Cliff

Thanks for the replies. I will renew my EAA membership. I  will have my granddaughter show me how to private message. I have on occasion browsed this forum. My computer skills are getting slightly better so I decided to try to join in. Thanks again, Cliff
