Transmitter stick mode
The stick assignment for the individual functions varies according
to the different modes - see also page 5.
Stick assignment, mode 1
Function 1: Roll
Function 2: Throttle (non self-neutralising)
Function 3: Pitch-axis (elevator)
Function 4: Yaw

Fig. 3 - Display and adjustment facilities in “H” mode (model
type: normal helicopter)
- The switch 1 (E) is used to switch the gyro between normal
mode and heading-hold mode.
- Normal mode:
the gyro compensates for changes in main rotor
torque; if an external influence such as a side-wind occurs, the
model will turn into wind.
- Heading-hold mode:
in this mode the tail stays “put” even
when an external influence such as a side-wind occurs, or if the
model is flying backwards.
- The left-hand rotary knob (C) is used to adjust the collective
pitch centre point. The adjustor should be left at the “10
o’clock” position as a starting point.
- The right-hand rotary knob (D) is used to adjust maximum col-
lective pitch travel. The adjustor should be left at the “1
o’clock” position as a starting point.
- The switch 2 (F) is used to switch the throttle / collective pitch
settings. Back position: normal flight; front position: aeroba-
tics.
- The switch 3 (Y) is used to select full or reduced travel for chan-
nels 1, 2 and 4. Top position: 100%; bottom position: 70%.
- Once any adjustments have been completed, the safety switch
“R” should always be moved to the “Lock” position; this action
disables the rotary knobs (C) and (D) and the push-button (G),
thereby eliminating the danger of operating or moving these
controls accidentally.
Note:
the transmitter and model are set-up correctly at the fac-
tory, so you should not carry out any changes to the reverse swit-
ches or rotary knobs. The safety switch should always be left at
the “Lock” position. The switch 2 (F) must be set at the “NOR”
position.
For smoother flying the Dual Rates switch 3 (Y) can be moved to
the bottom position (70% servo travel).
The transmitter also provides three additional model types; see
page 8 for an explanation of these. For the moment you can safe-
ly skip this section.
Operating the transmitter for the first time
Fig. 4 - Inserting the dry / rechargeable cells in the trans-
mitter
Open the battery compartment by pressing gently on the
cover and sliding it down. Insert the dry or rechargeable cells
in the compartment, taking care to maintain correct polarity.
Close the battery compartment cover again.
Note regarding battery charging: maximum permissible
charge current: 1 A.
The transmitter is fitted with a polarity-protection diode,
which prevents a short-circuit if the banana plugs on the
charge leads should touch.
If you wish to use a fast charger which exploits the “reflex
charge process”, this diode must be by-passed. Please con-
tact your nearest robbe Service Centre for details.
Using a reflex charger with the polarity-protection diode in
place will cause the automatic charge cut-off circuit to mal-
function, and the transmitter battery will be overcharged.
Notes regarding dry cells:
Never attempt to recharge dry cells. Do not open them, nor
incinerate them. Exhausted dry cells should be removed from
the transmitter without delay, otherwise electrolyte may esca-
pe, which can easily ruin the transmitter.
Take all exhausted batteries to your local approved collection
point.
Fig. 5 - Operating display
When the green LED lights up, the transmitter is ready for use.
If the red LED flashes (battery voltage below 8.5 V), or goes
out completely (below 7.6 V), land the model immediately,
cease operations and either replace the dry cells or recharge
the rechargeable cells. The actual voltage is also displayed on
the transmitter’s integral screen.
Figs. 6 and 7 - Changing crystals
The transmitter and receiver can be operated on different spot
frequencies within the prescribed frequency band by fitting
replacement crystal pairs - see crystal table in the Safety
Notes. The crystals in the transmitter and receiver are fitted in
sockets, and can therefore be removed and replaced at will.
Always take care to avoid channel clashes (two transmitters
on the same frequency). The spot frequency of the transmitter
and receiver must be the same. Transmitter crystals bear the
inscription FM Tx + frequency and channel number. Receiver
crystals are marked FM Rx + frequency and channel number.
Replacement crystals for the transmitter and receiver are
available from your nearest robbe Service Centre.
To change crystals, withdraw the crystal drawer from the
transmitter and replace the transmitter crystal.
Undo and remove the canopy from the helicopter. Withdraw
the crystal from the receiver, and fit the replacement crystal.
Crystals are not polarised; they can be fitted either way round.
