100 Digital trims

Description of function

Both the dual-axis stick units are fi tted with digital trim 
systems. When you give the trim lever a brief push (one 
“click”), the neutral position of the associated stick chan-
nel changes by one increment. If you hold the trim lever 
in one direction, the trim value changes continuously in 
the corresponding direction with increasing speed.
The degree of trim offset is also “audible”, as the pitch of 
the tone changes to refl ect the setting. When you are fl y-
ing a model, you can fi nd the trim centre position easily 
without having to look at the screen: if you over-run the 
centre setting, the trim stays in the centre position for a 
moment.
The current trim values are automatically stored. 
The digital trim only works when the transmitter is swit-
ched ON. When switched OFF, even an accidental touch 
of the trim lever does not change the set values.

Stick Calibration
If you suspect that the centre point of your self-centring 
sticks (transmitter controls 1 … 4) does not correspond 
exactly to 0% travel of the transmitter control, you can 
check and - if necessary - correct it using the following 
procedure:

Turn OFF the transmitter, and insert the supplied pro-
gramming plug into the DATA jack on the back and the 
jumper in position „DELTA“ on the front of the transmit-
ter. Bring both sticks in the middle position. Turn the ra-
dio ON. The transmitter starts beeping after one second 
for 10 seconds once per second. During this 10 seconds 
move both control sticks to all the end positions, so that 
the transmitter can save this positions. After expiration 
of the 10 seconds the calibration is completed and 
the transmitter is back in the normal mode, the beeps 
become silent. Turn the transmitter off and then remove 
the programming plug on the back.
