ground) and 12* negative ( and yes I can use all of it when light). The idea
was to keep all the flap you can get...so why would I intentionally make it
less. I've been bad and had them fully deployed at 100 MPH (takes a heck of
a pull on the handle!).... but mine are alum covered so a tad bit stronger
than 99% out there covered in fabric.......and I haven't blown them off YET!
Mine still flex up somewhat in flight...but nothing near like the standard
manual installation.
Howard's CYP has electric flaps. It's a cars seat mover unit mounted into
the side panel, below the rear window, with the bellcrank mounted right to
it so it goes straight up and down. That gets rid of the slight rotating
movement of the mixer arm that changes stick center as you put flaps on in
most Rebels. I personally hate electric flaps...but if you like them this
gives absolutely no flex and the absolute most positive flap movement you
can get. There is still flap lost from the torque tube twist, horns
flexing...rod end slop, attach bolt flex and the like..but not near the loss
of the push/flex in the teleflex cable.
Other things I have found that cause a huge loss of flap is the mixer arm
being assembled with too much slop in it, too much clearance in the guides
that let it tip and the bellcrank spaced out to far on the arm causing it to
twist back and forth. All of these movements cause loss of flap when
airloaded.
Cheers,
Wayne

Hi Wayne,Flaps sound normal for the Rebel (unless of course you have a full
mechanical linkage like I do!).
On your mechanical linkage setup, did you still use the flap angle
bein the manual or did you reduce it a bit? (since the cable setup reduces
the angle with air loads)
I'm playing around with the idea of tossing the cable in favor of a
mechanical linkage - maybe electric. I can see where the cable would have
slop in it - you're pushing on the cable to lower the flaps. That would
like trying to push a rope through a tube and expecting to do some work on
the other end wouldn't it?
Joel
