Ail.Diff. (aileron differential)

16.1.2.
For fixed-wing models only
Diff. : -100% ... OFF ... 100%
Adjustment
Prefix (+/-) reverses direction
range:
=> reduction of aileron up-travel or
down-travel
Separate values for differential ( Diff. )
can be set for each flight phase
The differential value ( Diff. ) can be al-

located to the 3-D digi-adjuster
( 20.1.)
A simple description of aileron differential:
If ailerons are set up with symmetrical travels, i.e. the
same deflections up and down, then the down-going
aileron on the outside of the turn generates more drag
than the up-going aileron on the inside of the turn.
This results in a negative turning moment (known as
adverse yaw) which tends to push the model out of
the turn. The model yaws - nose-high - as it turns.
Aileron differential reduces the adverse yaw effect by
reducing the deflection of the down-going aileron. Ai-
leron differential is only possible if a separate servo is
installed for each control surface. The effect of 100%
differential is that the ailerons only deflect in the "up"
direction (sometimes known as "split mode").
Aileron differential is not generally required for high-
speed powered model aircraft with symmetrical wing
sections. Model gliders usually feature cambered air-
foils, and in such cases a good starting point is about
50% differential. The optimum values can only be es-
tablished through practical flight testing. The more
highly cambered the wing section, the more differen-
tial is generally needed. That is why the system allows
you to set different levels of aileron differential for
each individual flight phase.
Example:
Glider with the following flight phases:
Ail.Diff. = 50%
NORMAL:
Ail.Diff. = 65%
THERMAL*:
Ail.Diff. = 40%
SPEED**:
* The ailerons (and in some cases the camber-changing
flaps) are lowered slightly for the Thermal task:
=> Airfoil camber increased
=> Greater aileron differential required
** The ailerons (and in some cases the camber-changing
flaps) are raised slightly for the Speed task:
=> Airfoil camber reduced
=> Less aileron differential required.

Parameter Mode :
The Mode parameter is used to activate or disable the
Aileron Differential mixer (switch it ON or OFF).
If both ailerons are raised in order to act as a landing
aid, then +SPOILER should be selected as the Mode.
This suppresses aileron differential when the landing
aid (transmitter control: Spoiler ) is extended. The
effect of this arrangement is that more aileron re-
sponse is available on the landing approach, since the
aileron travels are not reduced:
Parameter Diff. :
This is the point where the differential value itself is
set. If the differential works the wrong way round (ai-
leron up-travel reduced, instead of down-travel), sim-
ply reverse the value using the REV/CLR button.
Aileron differential can be set separately for each flight
phase. To set the values, activate the appropriate flight
phase using the flight phase switch " Phases 1-3 "
(the active flight phase is displayed in the top line, and
also by the number before the parameter) and set the
desired value for Diff. :

Controls Mix (transmitter control mixer)

16.1.3.
! These mixers are not global, but model specific,
i.e. they can be set separately for each model.
The transmitter Controls Mix mixes the signal from
any second control ( Source ) into any other transmit-
ter control ( Target ). The mixing affects all servos
which are connected to the Target control either di-
rectly or via a free mixer:

The mixer can be switched on and off using a mixer
switch ( Mix-1 to Mix-3 ).
