    My impression of my own flaps is the first notch is like standard flaps but subsequent notches “rotate” the nose down. Holding the flap button and moving the lever up and down between notches directly manipulates the attitude. Very interesting. My flaps are longer than most and I definitely have to slow way down to make pulling flaps practical. Above 40mph the pull effort is too high. I’m not used to these flap speeds but I expect I will be soon.

    Did you use the short version of the flap handle? I had the same issue with my long 110" standard shaped flaps. The solution was to lengthen the handle until it just cleared the bottom of the instrument panel.

    No need for a longer handle. I need to get used to flap speeds that are slower than my traditional stall speeds. If I land with three notches of flaps at near 30 mph the tail remains very high, like cruise attitude. If I try to bring the tail down the plane will fly. I'm not used to that. And I still have another notch that I haven't landed with yet. It's no problem, just me getting acquainted with my airplane. I'm sure some of the stock Supercub-Performance Flap guys that land a little faster than others will experience the same thing.

    Otters (single and twin) with a very similar double flap do the same nose down pitch with flap extension. When landing they look tail high and wheel landings are common after a noticeable pitch up just prior to touchdown. Just rode in them never flown.

    Hell of a rig! Guess I missed the boat on this one. Is there a link to the backstory on your plane?

    Experimental PA12 installation and test
    Initial pirep
    The experimental kit was well boxed and arrived without damage’
    The parts are all very well made and fit well.
    Installation was relatively straightforward following the instructions
    One notch of flaps significantly reduced the take off time on pavement
    With one notch of flaps it got on step quicker on floats
    Application of the full flap deflection decreased take off time off of water significantly

    Keller flaps

    Looking for real world experience comments on Keller flaps. I’m building an experimental PA18 and considering the Keller flaps. They are offered in 2, 3 and 4 hanger versions with price ranging from $6400 to $8400 respectively. Basically, I would like to know if those folks that have flown them think they are worth having and would you do it again? Why, or why not? Also, which of the three options (2,3,4 hangers) do you have? What made you choose that option?

    Thanks for any information/insight you are able to offer.

    Mr. Ed

    Ed, here’s another thread to review. http://www.supercub.org/forum/showth...nsion-some-how

    Mine are 112”. First notch flap speed is 60 mph. My first notch is a baby step. The second and subsequent notches require considerable effort to pull even using 40 mph as a target speed. The effect of the second and third notch is like using a lever to roll the nose down. How your cables are rigged willl determine how much actual deflection you maintain at landing speeds. Mine seem to be doing okay as I learn to slow the plane adequately. In my Cub the top pulleys are attached to the relocated upper longeron. The cable tension was great enough to flex the longeron and that contributed to the flaps “blowing back” from reduced cable tension. We added a brace leg to fix the deflection. The point of that comment is that the cable tension is high with these big flaps. How your pulleys handle it is worth consideration. My own pulleys are all braced to prevent flex and ultimately breaking the attach welds. At the end of the road? The flaps work great. With my slatted wings they allow very slow speeds at a normal approach attitude. Two thumbs up.
