Elevator trim compensation for ﬂ ap commands

If elevator trim correction is required when the cam-

ber-changing ﬂ aps are deployed, this can be set up in

the menu …

… by selecting the “Flaps 6  3 Elevator” mixer, and

entering a suitable value in each ﬂ ight phase. If you

have assigned the same transmitter control to inputs

5, 6 and 8 – as described above – then all six ﬂ aps

move simultaneously, while the elevator moves in ac-

cordance with the set mixer input.

Flap following for elevator commands

The ﬂ aps can be set up to reinforce the effect of the

elevator; this is normally used in high-speed ﬂ ying to

improve the model’s agility around the lateral axis,

and is also set up in the menu ...

… by setting the mixers “Elevator 3  6 Flaps” and

“Elevator 3  5 Aileron” separately for each ﬂ ight

phase. Both the secondary ﬂ aps (servos 6 + 7) and

the ailerons (servos 2 + 5) follow the movement of the

camber-changing ﬂ aps in accordance with the set mi-

xer ratio – usually in the opposite direction to the ele-

vator.

To force the two inboard ﬂ aps (servos 8 + 1) to “fol-

low” this movement, move to the menu ...

… and set up an “EL  8” mixer for each ﬂ ight phase.

These mixers have the effect of making both inboard

ﬂ aps follow in the same direction when an elevator

command is given – provided that you have already

set up the dual mixer as described on page 142.

On the second page of the screen, set up a mixer ra-

tio suitable for the model and the ﬂ ight phase in ques-

tion.

To ensure that these mixers – in our example Linear-

MIX 2 and LinearMIX 3 – work as required in the ap-

propriate ﬂ ight phases, you now have to move to the

menu ...

… and determine which mixer is to be disabled in

which ﬂ ight phase. This is done by switching between

the ﬂ ight phases and setting the two mixers to “yes”

or “no” as required.

Using airbrakes

If the model features airbrakes in addition to the wing

ﬂ aps – and if your receiver still has a vacant output

socket (9 or higher) – you can control them using the

Ch1 stick, which until this point has not been assig-

ned a function. To do this you have to set up a further

free mixer “Ch1  9”, which causes a servo connec-

ted to output 9 to extend and retract the airbrakes.

If necessary you can adjust the characteristics of the

airbrake control system in the »Channel 1 curve«

menu.

If your model needs automatic elevator trim correction

when you extend the airbrakes, this can be achieved

without the need for an additional mixer. Simply use

the pre-programmed wing mixer “Brake  3 Elevator”

in the »Wing mixers« menu.

However, you still have to ensure that the elevator is

not affected by the Ch1 stick when the airbrakes are

retracted, and to this end the mixer neutral point (off-

set) of the “Brake  3 elevator” mixer has to be ad-

justed accordingly.

This is carried out in the menu ...
