George,
I know you emailed with the newsletter thread but this warrants a thread
of
its own.
First Adjusting the Ailerons will not correct any roll problem in an
aircraft with push rod system similar to ours. The =93system=94 will
simply fly
in a different position and you r stick will be off center. The ailerons
should be neutral with the tips of the aircraft with the stick centered
vertically.
Next measure the difference of angles between your flaps. You can
measure
the gap up or down from the wing roots on the fuselage for reference or
use
an digital level on the bottom surface of the flap. I would suggest
only
having about a =BC=94 difference in flap angle if using the fuselage as
a
reference point, or about 5 degrees in flap differential.
IF the flaps are currently at deferent angles, and adjusting will help
the
eliminate the roll and make them closer to even, than do that first.
If they are even, than try dropping one and raising the other. In your
case
some left flap drop and right flap rise will help.
Now if the flaps are adjusted to the maximum suggested, than its time to
put
a small tab on the aileron. Build the tab from a 2=94 by 6=94 piece of
0.040
aluminum. These seem to be more effective if bent down to fly the
aileron
up, so a small tab on the right aileron bent down will help the roll.
As for attaching the tab, most hardware stores have what called
=93gorilla
tape=94 this is a 2 sided tape that will hold just about anything
together.
This will be good to test the tab, once happy than bonding it on is the
permanent solution. Bond the tab on by; sanding the aluminum with 60
grit
paper on the portion that attaches to the aileron, do the same to the
aileron. Wipe clean with acetone or similar to degrease. Use some good
structural epoxy for this, 24 hour is not needed but if that is what you
got
ok, make sure to mix some flox in as well to provide a filler for the
small
voids.
There are many more ways to correct the roll, and maybe we will get some
more suggestions.
