Ok, thank you. Very hard to believe that an airfoil in free stream would behave similarly to the same airfoil tucked closely behind another body. I'm obviously missing something. I'll go back and

There I virtually no aerodynamic impact of the transition from the fixed elevator slot core to the elevator, so if that is what you mean, then no there is no effect. Cheers, Jay

"Elevator Slot" = "pocket" (pic taken from http://samhoskins.blogspot.com/search?updated-max=2014-06-18T04:55:00-07:00&max-results=20&start=27&by-date=false) -- Q2 N86KL

Not sure what you mean by “pocket”??

Here is about the best pic I could find without going out to the airport (sore throat). If I get a chance I will go to the airport for a side view so it can bet better evaluated. This is my set up

Jay, this is all very interesting. Do your (model) numbers for the above profile include the effect of the pocket that the elevator partially occupies and the gaps to the trailing edges of the

Hi Brian, So here is the non-engineering answer: The solution was developed a long time ago. John Roncz solved most problems for the Long EZ canard by introducing the new airfoil (Roncz

We think so..but remember that aerodynamics since 1980 has itself changed quite a bit, Brian. Aerodynamics is still an evolving study. Actually Manufacturing and Structures Design is also. Internal

My non engineer question. Is there an efficient solution with a change to the shape of the elevator? Would seem that if there was that it would have been developed a long time ago. Brian

Thanks Michael, I did read this after David pointed me in that direction. The problem with this approach is that the net moment arm is smaller because it is closer to the trailing edge, and the

Jay, that RAF CP 59 that Dave listed makes some interesting points. Burt recommended fixed tabs riveted on (and 10" long, to boot) to unload the elevator trim springs; different idea but something to

Not sure 4000 it's ready to have the wings on tons of parts there I couldn't load all the pictures

Am local. What you looking to get out of it? Thanks. Paul.

What I was thinking also, Brian. Either larger area as in Peter's Sparrow Strainers on his aircraft which he trimmed by flight testing until best effect..or in cleaner air below the canard. Further

Ah! Yes, so the prop blast is assisting the prevention of totally Stalled. Several aircraft use that same principal for additional lift at lower airspeeds but at higher airspeeds I would think that

27 degrees AOA is a lot. One would think lowering the AOA of the Strainer Clark Y, thereby taking it out of a stall condition, would increase the effective "inverted lift". Is everyone using the
