Preparation For Start; Receiver's Binding; Transmitter Settings - GRAUPNER Race copter alpha 250 Q Manual

Setting the flight mode - attitude or
Rate mode
Do not forget to set the Fail-safe!

preparation for start

To start fling you need the following items:
Ð Transmitter (MX-12 / MZ-12 or higher)
Ð Battery pack Graupner 9717.3.D35 or similar
Battery installation
Fix the battery in its compartment using some hook-and-loop
tape. Place the battery so that the copter's centre of gravity is
in the middle of the frame.
Binding the receiver with the transmitter
Read the transmitter and receiver manual before you try to
bind them.

Receiver's binding

The binding is only possible if the receiver has not yet been
binded to another transmitter (red LED blinks). Pushing the
SET button the receiver will be set in Bind mode.
If you want to bind an already binded receiver to another
memory, follow the next steps:
Ð Turn off the RF module in the "Basic setting" menu (see
transmitter's manual)
Ð Switch on the receiver pushing the SET button to bring it
in bind mode
Ð Start the binding in the "Basic setting" menu
Ð If within 10 seconds the red light turns off and the green
LED will light, the binding process was successful. Your
RC system is now ready for use.
Ð If the red LED is still on it means that the binding process
didn't work properly. In this case repeat the procedure.

transmitter settings

In the transmitter it must be selected a free model memory,
the model type must be "surface model" and the channel 1
direction must be set to channel 1 in "motor off" position in the
power indicator must show -100%.
The flight mode must be set on channel 5. Then program a
two-way switch for channel 5 to control the flight mode:
attitude mode: Channel 5 = -100% to 0%. The stick movement
determinates the Copter reaction on Roll and Nick. It allows
a maximal angle of about 50° at 100% of stick movement.
Mode suggested for beginners. The stick movements acts
directly proportionally to Roll and Nick.
Rate mode: Channel 5 = 0% to +100%. The stick movement
determinates the rate without angle limit. Aerobatic mode that
allows Rolls and Loopings.
We suggest to set the fail-safe on channel 5 at -100% , so
that in fail safe it is active the attitude mode.
