Survey - the essentials

14

The unit is as simple as we could make it in terms of setting-up and flying. 

However, if you are a beginner to helicopters it is really essential to ask a friend 

with experience of flying these machines to help you at the initial test-flying 

stage, as the functions of a helicopter are very complex. 

This double page and all the points marked with an exclamation mark  

  

are particularly important, and should be read carefully even by pro-standard 

pilots.

 

Installation

  Mount  only  by  using  the  supplied  self-adhesive  soft  foam  stripes,  strictly 

  according to the instructions (pages 16-18).

 An electrical connection must be created as an earth between the tail boom,  

  the motor crankcase and the helicopter chassis.

 The higher in the model the unit is installed, the smoother the stabilisation in  

  position mode when close to the ground.

 Please ensure that the unit is set vertically, securely fixed in the model, and  

  with an absolutely unobstructed view between the sensor and the ground.

 Important  notes  for  internal-combustion  helicopters  and  comprehensive  

  installation tips: see page 19.

Transmitter 

All the mixer functions for elevator, aileron and tail rotor must be disabled: al-

ways set single-servo mode (H1 or CCPM), as the 

HeliCommand

 is designed 

to use its own internal mixer exclusively.

Configuration

The unit must be configured in order to match it to the model and the   

RC system; this only needs to be carried out once (page 23). 

If the standard default settings suit your model and RC system (page 22) this 

setup can be omitted.
Before the first flight with the system it is essential to check the controls and 

sensor directions on all three axes! (page 28)
