1357.0. "Great Planes Cap 21" by N25480::FRIEDRICHS (Keep'm straight 'n level) Fri Sep 13 1991 12:03

    Anyone out there flown the Great Planes Cap 21??  
    
    I was lucky enough to buy the one recently for sale in here.  It is
    the .40 size..  I am hoping that my trusty K&B .60 will fit on it (is
    that Eric smiling there??)
    
    So, does anyone have any building/flying hints??  I have heard that
    they have a real tendency to snap roll at slow speeds.  I am planning
    on adding flaps to try to reduce this tendency on landing...
    
    Thanks!

    Jeff,
    	Keep it as light as possible and you'll be happy with it.  Make it
    heavy, and you'll snap it when using too much elevator.

Jeff,
I may be wrong but I think there was a letter published in either MA or RCM from
an older gentlman who had about given up on his Cap 21 as being too much for him
to handle. The bigest problem was snapping while trying to land. He ended up 
turning the plane into a pussycat on landings by adding turbolators strips 
to the top of the wing. Something to think about...

Being real helpful here, I know, but I have a feeling it was in MA in the front 
letters column with in the last year.

    Jeff,
    
    did you try those turbulator strips on top of the wings ?  I'm curious
    because my big CAP20 has the same tendency to snap roll on too low
    speeds.
    Annother suggestion when using ailerons that are just on the outer side
    of the wing is : on landings mix a flap function UPWARD to the
    ailerons. It helps quite a bit to reduce the snap roll tendency. But
    still am I curious to try those turbulator strips....
