    Alaskan fowler flaps and inline engine thrust mounts

    Has anyone a combination of the above.What effect do the flaps have on the approach trim etc?

    I installed the Thrustline mod and I still preferred two turns of nose down trim on landing. After installing the P STOL Flaps I do not need to touch the trim except to trim the load after I level off in cruise. Other Super Cubs I have installed the Thrustline mod on needed no trim from cruise to landing.

    I have a stock wing and engine mount Cub with with P STOL flaps and also do not change trim from cruise to full flap deployment once the Cub has been trimmed for the load. The experimental Mackey slatted wing with SQ 2 ailerons I recently completed requires lots of trim as it slows and the flaps are deployed which is the main reason for electric trim on this aircraft to speed the trim changes needed.

    Further to my Query, with a full flap approach would you guys say the aircraft requires much more power ? Does this situation improve stability?

    No more power, more stable, rock solid.

    And flies slower, stalls slower, all around more stable/solid as Steve says.

    Don't you have the long flaps on your Cub Ron? Those performance details sound a lot like the 110" flaps on my Cub. It would be interesting to hear from someone who has the long flaps and who has changed to the double slotted Keller Alaska flaps.
