1. INTRODUCTION
Many thanks for purchasing the Graupner M-G2 HoTT 2.4 module. This module is a direct replacement
for the standard RF module
fi
tted to your mx-22, mx-24, and mc-18, mc-20, mc-24 transmitters.
Please read right through these instructions before you attempt to install and use the system.
Installation requirements
We recommend that you have the module installed by a Graupner Service Centre. It is possible for
the modeller to carry out the conversion himself provided that he has a certain amount of manual skill,
but the transmitter’s
fi
rmware needs to be updated for the
fi
rst time in order to integrate the telemetry
display - also the Telemetry PCB Order-No. 33306 is necessary - (mx-24 and mc-24 only), and this can
only be carried out by the Graupner Service Centre Germany. Please note that we cannot offer a gua-
rantee for all failures which have been caused by incorrect installation, if you carry out the conversion
work yourself.
2. PREPARING THE SYSTEM
mc-series
First remove your previous RF module. For details of this procedure please refer to the appropriate
chapter in the operating instructions supplied with your radio control system. If you have previously
used a 35 MHz system, you will also need to replace the telescopic aerial with the Graupner HoTT aerial
supplied in the set.This requires the use of the aerial conversion kit for tray-mounted transmitters, Order
No. 23049, and the aerial, Order No. 33801 - see Figs. 5 to 10.
If you have previously used a 2.4 GHz system such as Graupner iFS, all you need to do is unplug the
existing aerial from the module.

First remove your previous RF module. For details of this
procedure please refer to the appropriate chapter in the ope-
rating instructions supplied with your radio control system.
If you have previously used a 35 MHz system, you will also
need to replace the telescopic aerial with the Graupner HoTT
aerial supplied in the set.
This is the procedure:
fi
rst unscrew the telescopic aerial from
the transmitter, then pass the aerial wire attached to the
HoTT aerial through the opening, working from the top. The
mounting adapter (1) features a small notch on one side (see
detail), through which the aerial wire is routed; this must be
on the left-hand side, as seen from the front. Fit the adapter
in the opening, followed by the tubular spacer (2), with the
hole for the retaining screw facing the rear. Now secure the
adapter by tightening the gold-coloured M4 screw (4) fully.
The
fi
nal step is to
fi
t the aerial on top and secure it with the
black self-tapping screw.
If you have previously used a 2.4 GHz sys-
tem such as Graupner iFS, all you need to
do is unplug the existing aerial from the mo-
dule.
