Installing The Receiver; Preparing The Helicopter; Transmitter Presettings - GRAUPNER GR-18 Notice D'utilisation

Maximum altitude (max. altitude): This is where you can specify a maximum altitude. When the model reaches this
altitude, an alarm is triggered either by the transmitter's RF module in the form of a "general alarm tone" (regular beeping
at a rate of approx. one beep per second) or the "altitude" speech output message. Note: When the receiver is switched
on, the model's current altitude is set to 0; the displayed altitude is therefore the altitude relative to the launch point.
Cycle time (PERIOD): If your system is used exclusively with digital servos, you can set a cycle time (frame rate) of
10 ms. If your system includes some or uses exclusively analogue servos, you should always select 20 ms, as many
analogue servos cannot process the higher frame rate and may respond by "jittering" or "growling".
HoTT sum signal (SUMD): If the digital sum signal is activated at channel 8 (6 for GR 18), a sum signal with 8
channels is issued from this socket (instead of a servo signal). The HoTT receiver configured as SUMD
constantly generates a digital sum signal from 8 control signals from the transmitter and makes this signal
available at the specified servo socket, which is receiver-specific. At the time this manual was revised, this
type of signal is used by several of the latest electronic developments relating to heavy-duty power supplies, etc.
WARNING: If you wish to use this option, you must observe the
setup information supplied with the device connected to the receiver, otherwise there is a risk that your model
may be uncontrollable.

Installing the receiver

The receiver must be aligned at right angles to the helicopter on the receiver platform. Please ensure you always
observe the installation instructions in section 3.1. Prior to installation, remove the sticker on the back of the receiver.
We recommend using double-sided tape (order no.: 96382.1) to fix the receiver in place.
The receiver must be connected to a stable power supply with at least two power cables. Comply with the maximum
power consumption permitted by the servos.
Caution: The receivers may only be used in electric helicopter models.

Preparing the helicopter

Set all servos to neutral; the arms must be at right angles and the swashplate must be in the neutral position (perpendicular
to the main rotor axis). The swashplate pushrods must be the same length.

Transmitter presettings

Select the free/deleted model memory and activate the helicopter model.
All trims must be set to 0 and must not be altered in flight under any circumstances. If possible, trims should therefore
be deactivated in the transmitter. With transmitters MX-20, MC-16/20/32 and mz-18/24, disable the trim in the menu.
(Set trim increments to 0).
• Activate or retain the servo for swashplate type 1 (the swashplate mixer is implemented in the FBL system)
• The travel of the gas channel (K6) must be set so that a value close to -100% (servo display) is reached when the
motor is off, as otherwise gyro calibration will not take place.
• Transmitter travel settings always remain at 100% for the basic settings
• Do not connect the tail servo if it does not have a mid-point of 1.5 ms (standard).
• Swashplate servo arrangement at 120/135/140 degrees:
front left = 1, front right = 2, back =3
• Bind the receiver to the transmitter
• Access the receiver's "Telemetry" menu and set the model type to "Heli" in the first row of the first screen
• Set all the servo settings on the transmitter to neutral (servo display 0%)
