19.2 THROTTLE CURVE SETTINGS

Operating the throttle stick moves the throttle servo, but also

automatically operates the collective pitch servos. The match

between collective pitch and throttle is very important, and for

this purpose the thr

ottle function can be assigned one of six

possible curve types, each of which can be allocated a maxi-

mum of seventeen variable points. The FX-40 also offers swit-

chable flight modes which enable the pilot to set up the opti-

mum throttle curve for each individual flight mode.

To move to the throttle curve set-up screen, mark this option in

the Model menu (‘Helicopter’ type already selected). The

screen now looks like this:

For the model helicopter application, the throttle and collective

pitch functions are always intimately connected. It therefore

makes obvious sense to have direct access to the collective

pitch function from the throttle curve set-up screen. You can

switch to AFR programming for the collective pitch function by

marking the appropriate field in the first line. The active display

always has a red background. It is possible to determine whet-

her the settings are to apply to all flight modes (Glob) or only to

the currently activated flight mode (Sepa) using the ‘Glob’ or

‘Sepa’ button field. The change takes place when you confirm

the security query.

• Programming throttle curves

In this menu for the following flight modes throttle curves

can be set up:

Normal: for starting and stopping the motor

Idle-up 1: for hovering

Idle-up 2: for circuits

Idle-up 3: for aerobatics

Auto-rotation: for auto-rotation landings

Flight modes 6 - 8: for any other purpose

If you wish to set up dif

fer

ent throttle curves, you must first

switch from group mode (Glob) to individual flight mode

(Sepa). You can switch between these two curves (flight

modes) by operating the switch (flight mode switch) assigned

to that mode (see Section 17.1, page 55). When you switch the

transmitter on, the Normal flight mode must be selected; if not,

the mixer alarm sounds. The RF section can only be switched

on in ‘Normal’ mode.

Throttle curves are programmed using the familiar procedure.

First you have to define the curve type: five curve types are

available via the corresponding fields, in addition to the stan-

dard linear curve. The values are adjusted exactly as descri-

bed for programming the Dual Rate curves. Please refer to

Section 17.2 on page 57.

This shows a typical throttle curve for the ‘NORMAL’ flight

mode. The curve should be programmed in such a way that
