Do not use excessive force when tightening the aerial: no
tool is required!
! Note: at regular intervals check that the aerial is firmly
seated, and the screwed joint is still tight.

HANNEL EXPANSION MODULE
Graupner mc-18, mc-20 and mc-24 transmitters with M-LINK
technology can be expanded by four fully proportional auxiliary
channels using the channel expansion module (# 7 5810). In
typical Graupner terminology this corresponds to eight sup-
plementary channels.
Once the channel expansion module has been fitted, up to four
additional transmitter controls can be connected, with an option
of two-position or three-position switches. In this regard please
refer to the notes in the operating instructions relating to the
channel expansion module.
Due to restrictions inherent in the system, the four auxiliary
channels cannot be configured or adjusted using the trans-
mitter's software.
! Note: the four expansion channels are dynamically "ap-
pended" to the PPM signal, and therefore have no fixed channel
assignment, i.e. when the transmitter is operated in different
PPM modes, the auxiliary channels will be present under
different channel numbers: PPM 18 -> channels 10 – 13; PPM
24 -> channels 13 - 16.
This is the procedure for installing the channel expansion
module:
1. The channel expansion module can be installed in any
suitable location inside the transmitter. Ensure that there is
no possibility of a short-circuit once the unit is fitted. The
transmitter battery must be left disconnected all the time
you are carrying out this work (
The following section describes the method of attaching the
unit directly to the stick housing (dome):
2. Position the channel expansion model at its eventual lo-
cation, and fix it to the stick housing (dome) using a self-
tapping screw. Don't over-tighten the screw!
3. Connect the lead to the socket marked "EXT." on the 2.4 GHz
HFMG1 M-LINK RF module and to the circuit board of the
channel expansion module.
! Caution: note the correct orientation of the JST sockets;
do not force the connectors together. Refer also to the
sketch on the 2.4 GHz HFMG1 M-LINK RF module.

4. Deploy the JST lead as described in section (
result should look like this:
5. Remove the plastic switch blanking plates at the wells where
the additional transmitter controls are to be installed (
Point 2.).
6. Install the controls at the switch positions.
7. Connect the leads (sockets) of the supplementary transmitter
controls to the appropriate sockets on the channel expansion
module.
8. If the total number of servo channels to be transmitted is
greater than twelve:
You will need to disable the "Fast Response" setting (
on the 2.4 GHz HFMG1 M-LINK RF module, otherwise the
supplementary channels will not be transmitted.
9. Now re-connect the transmitter battery (

DEAL POSITION OF THE TRANSMITTER
AERIAL WHEN USING THE SYSTEM
When installed, the 2.4 GHz transmitter aerial can be rotated
and set to any angle.
Before using the transmitter, the aerial should be angled
approximately at right-angles at the swivel joint, then swivelled
either to left or right in the horizontal plane:
For applications where the model is not operated directly above
or below the transmitter, the optimum aerial orientation is verti-
cally upwards; this applies in particular to model cars and boats:
