Les,
I tried the Tom Hoopes method (article referenced on Charles River RC
website) and was not satisfied with it. The whole point of reverse
differential is to allow larger amounts of crow (ailerons acting as
spoilerons when flaps are down). While Hoopes' method did increase the
reverse differential, it also seemed to effectively cancel the crow on
my ailerons. What is the point in that case?
I came up with:
Mix #2
AILE->FPRN
SW: BTFY 1
Multi-point / \
curve like / \
this: / \
/ \
/ \
L 1 2 3 H
The mix value at L and H is some negative number like -75. At the
mid-point (2), it is zero. The intermediate points (1 & 3) are
inhibited. What this does is mix in negative flaperons at the left and
right extremes of aileron travel, i.e. reverse differential. The exact
values in the mix curve depend on how much aileron crow you have set up
in the Butterfly menu. Works for me.
