Mike, We retained the "aileron droop" feature which can be utilized if the
pilot so chooses. The flap setup allows for a negative setting to match the
negative aileron position if the pilot chooses. It sounds a bit complicated
but in practice it is not.
I don't usually choose to use the "aileron droop" feature upon landing
simply because of the feel of adverse yaw and heavy ailerons. Maybe I
should do some playing with the features on a nice still day.
I don't recall the degrees of up-elevator available. I will check that. I
do recall that the Murphy recommended incidence for the tail plane did not
work at all. That was quickly changed.
Securing 60 or so pounds aft of the seats makes a big difference when the
airplane is lightly loaded. This is a pretty strong clue as to what the
problem might be.
I don't have any problem with the rigging and C of G as it is. I just find
it difficult to 3-point the thing each and every landing.
Thanks for the suggestions.

Hi Collin !
One thing that is very important on the Rebel - be sure you have
AT LEAST 27 degrees of UP elevator travel - don't worry too much if
this reduces the down travel to 20 or less ... The other important
factor is the C of G - it will definitely work best if the empty
C of G is around 12 inches -- not that you can't do good landings
elsewhere - my c of g is only 8.1" !! As I mentioned, I find it
easiest to approach at 75 mph - much safer & more comfortable than
dragging it in with power, and it is easier to do a good landing
without the extra variable of power in the mix.
You mention you have "flaps installed" - if that is the split
flap arrangement, that could be the problem. Everyone here uses the
original flapperon setup - especially on floats. It works great
because it changes the shape of the whole airfoil of the wing !
With the split flaps, you get half the flaps and half the ailerons -
not so good in crosswinds, or for short landings. :-(
You also lose the increased cruise speed and better ride in bumpy
air that negative flapperon gives.

100

mains.
The tail wheel follows almost instantly after a proper power-off approach
but I cannot call it a true 3-point.
I am interested in knowing how folks are getting the tail wheel down prior
to the mains. I don't seem to have the elevator authority.

No finished plane to play with yet, but I was asking about adding flaps in
this because I've gained some impression that many Rebel pilots don't use
them much. I thought that because of the typical pitch down with flaps,
adding them might help with getting a slow 3-point landing without the
tail
hitting way early. Glad to hear Bob that you find the flaps useful all
the
time -- i was beginning to wonder.

Hi Ben !
Not sure what you are running into ... if the tail touches first
it's only by 1/2" or so - hardly noticeable. Playing with power
will get you into trouble every time ! I close the throttle as
soon as the runway is made - maybe 200-300 ft up ... and don't
touch it until you want to taxi !
I always take off & land with full flap - that's the way the
Rebel was designed to work. Approach at 75 mph - for safe penetration
of wind shear, and quick descent over trees -- aim a bit before the
numbers, flare & fly level, trying to keep it in the air. This
means <slowly> pulling back, the 'float' gives time to get the tail
down into the right angle, not much time, as the speed bleeds off
quickly with the flaps down. " If the stick is ALL THE WAY BACK
when the wheels touch, you'll have a good landing. " - heard
that often from old instructors ! :-)

Ken or others,
Does addition of flaps reduce the tendency for tail to hit first in an
attempt to do a slow landing, e.g, 3 point, even with some power added
as
well to limit sink rate?
