whatever the case may be, you should consider a logical 
assignment of the control mechanisms before you begin 
with the model programming.
For models in which the emphasis is on the "motor", 
regardless of whether it is powered by an electric 
or combustion motor, there should be no problem 
in this respect, because the assignment of the two 
joystick units essentially lies in the four basic functions 
"Power regulation (= throttle)", "Side", "Altitude" and 
"Transverse"! However, in the menu …

… you should determine whether you would like 
the minimum throttle position in the "front" or "rear", 
because "none (motor)" is entered by the program in the 
creation of a model memory as a basic principle.
The difference between "no" and "idle front/rear" is 
not only in the effect of the C1 trimming, which is over 
the entire joystick path with "none" and with "idle front/
rear" only effects the idle direction. In the process, 
the "effective direction" of the C1 joystick is adapted 
accordingly, so that with a change from "front" to "rear" 
or vice versa, the rotational direction of the throttle servo 
or brake system do not have to be adapted as well. 
In addition, with an "idle front/rear" setting, a warning 
indication appears in the display for safety reasons and 
issues a warning beep, if the throttle joystick is too far in 
the full-throttle direction:

In any case, you will also have to consider "special 
functions". 
With electro gliders, on the other hand, it is only 
occasionally different. In this regard, one must ask 
how the drive and brake system are actuated. Certain 
solutions have shown to be practical and others have 
shown to be less practical.
For example, it is certainly less practical, if you have to 
release a joystick for the approach of a glider model in 
order to be able to appropriately control the spoilers or a 
crow position using one of the other controls. It may be 
more advantageous to either design the function of the 
C1 joystick to be switchable (see Example 4, beginning 
on page 247) or to leave the control of the brake system 
at the joystick and to control the motor through one of 
the other controls or even with a switch! Since this type 
of model does not normally have a motor, and just a 
"start assistance" function to either "lift" the model in 
the sky with full force or, in any case, to "tow" it with 
"half" force by a wind fi eld, Therefore, the motor can be 
switched on and off without having to release one of the 
joysticks  – even in the approach. The selection is not 
diffi cult with the 

mx-20 HoTT transmitter.

For the control of the motor you use a two-stage switch 
SW 3 or 8 or, even better, one of the two three-stage 
switches CTRL 9 or 10. In any case, select a switch 
which you can reach easily in order to perform this 

option without having to release the joystick. In addition, 
this procedure should take place on the transmitter side, 
which is modifi ed for a holding hand with a manual start 
of the model. In other words: If the model is started from 
the right hand, the motor switch should be assigned to 
one of the switches available on the left side and vice 
versa.
The idea is the same for the control of fl aps, regardless 
of whether only ailerons or fl aps covering the entire 
wingspan (combinations) are raised or lowered.
If everything is now in order, you can begin with the 
programming.
