This  socket  allows  you  to  use  it  either  for  telemetry  or  for  an  extra 
channel  (9).  (Note:  Using  both  at  the  same  time  is  not  possible!) 
Switching is done in this menu item.  

 

receiver channel 9. 

Gyro Initialization  

After switching on your multicopter, the gyro is already active but not 
yet initialized. To initialize it, hold the Multicopter still after switching on 
preferably on a flat surface. The calibration will be done only when the 
receiver is completely still. After approximately three seconds you will 
hear beeps emitted by all motors. The signal tone can vary depending 
on  the  ESC  model.  The  beeps  will  stop  when  the  calibration  and 
initialization is complete. Wait until the initialization is complete before 
you  start  the  model!  The  motors  will  not  start  until  the  calibration  is 
complete. 

Transmitter Setup 

Before  flying  your  multicopter  you  will  need  to  make  certain  radio 
settings.  First,  create  a  new  model  setup  as  airplane,  single  aileron. 
For safety reason we highly recommend to have a switch or control 
configured as a throttle HOLD function that when active disables the 
throttle from accidental stick movements. For additional information as 
to how to setup a throttle HOLD consult your radio manual. 

The  GR18  controller  provides  two  flight  modes  to  control  your 
multicopter which is fixed to channel five on the receiver. You will need 
to setup a two-way switch for channel five in order to control the flight 
modes. 

Attitude  mode:  Channel  5  =  -100%  to  0%.  The  stick  movement 
determinates the Multicopter reaction on Roll and Pitch (Nick). It allows 
a maximal angle of about 50° at 100% of stick movement. This mode 
is  highly  recommended  for  beginners.  The  stick  movements  acts 
directly proportionally to Roll and Pitch (Nick). 

Rate  mode:    Channel  5  =  0%  to  +100%.  The  stick  movement 
determinates  the  rate  without  limit.  This  aerobatic  mode  allows  rolls 
and loops. 

Main settings 

TYPE

 

Quadro x, , Hexa I, Hexa V,Tri L, Tri R 

Make sure that your channel connections to the receiver are correct 
for the selected multicopter type. Also note the proper motor and 
speed controller direction as seen from the top. In case of tri-
multicopter use only a digital servo for servo 4 (channel 4). 

STEP ONE:

 Setup your transmitter for 

throttle hold and flight mode – 
Attitude or Rate mode 

STEP TWO:

 Select your multicopter 

type and calibrate the ESC’s. 

Make 

sure that your propellers are 
disconnected from your motors!
