Simple Transmitter Setup – Aerobatic Airplane (ACRO)

Setting Up A->R Mixing (Rudder Coupling)

1. Press one of the Up Down

Edit buttons until the A->R win-

dow appears, as shown. The

default is for the function to be

inhibited, as shown.

To activate, press the Active/

Inhibit (Clear) key.

The letters “INH” will turn to “100,” and either the ON indicator

or the OFF indicator will be flashing,depending on the position

of the Rudder D/R switch.

2. Press the Cursor Right key once, and the Percent sign will

be flashing. Move the aileron stick all the way to the right, and

adjust the R/D mixing amount by pressing the Data +Increase

or -Decrease key. You may set any amount between 0 and

100% (an initial value of 10-20% is suggested). To return to

the initial 0% value, press the Active/Inhibit (Clear) key.

3. Move the aileron stick all the way to the left, and adjust

the L/U mixing amount in the same way. To return to the

initial 0% value, press the Active/Inhibit (Clear) key.

Setting Up E F Mixing

1. Press one of the Up

Down Edit buttons until

the E->F window appears.

The default is for the

function to be inhibited. To

activate, press the Active/

Inhibit (Clear) key. This will cause the INH display to

change to a number display, and either ON or OFF will be

flashing depending on the position of the Flt. Mode switch

(fully aft turns it ON).

2. Press the Cursor Right key to get the percent sign

flashing, then press the Data +Increase and -Decrease

keys to increase or decrease the amount of mixing.

Check the direction the flaps move with elevator stick:

with up elevator, the flaps should droop downwards, and

for down elevator they should come up. In other words,

they should move opposite the elevator motion. If they

don’t, use the Data +Increase and -Decrease keys to

change the sign in front of the percentage number. You

should probably start with a smaller number (say 20% or

so) and slowly increase it to learn how the model reacts.

Remember the position of the Flt. Mode switch turns this

function on and off (fully back turns it ON).

A->R - Aileron -> Rudder Mixing

Aileron-to-rudder mixing is a function which causes the rudder

to move automatically with the motion of the aileron stick. This

is done because when ailerons are used to command a turn,

the down-moving aileron has more drag than the up-moving

one, so the plane’s fuselage tries to yaw against the turn. Add-

ing rudder mixing cures this problem by making the fuselage

point straight into the oncoming air stream (this is also called

“coordinating the turn”).

The slower the model flies, the more mixing is needed, and

the faster it moves, the less is needed. It is ideal to make

slow-flying scale models fly realistically.

The amount of coupling is highly dependent on the model

configuration.

Usually only a small amount of rudder is needed. It will also

help to set up some aileron differential using the EPA menus.

This function is turned on with the Flt. Mode switch fully Back.

A good starting point is to limit

the ailerons’ down motion to

50% to 75% of the up-moving

aileron’s motion. The aileron to

rudder mixing function is

turned on and off by the

Rudder D/R switch.
