Setting Up - GRAUPNER heim UNI-Mechanik 2000 Mode D'emploi

9. Setting up

9.1 Setting up the cyclic control system
The basic settings of the roll and pitch-axis control systems should already be correct if you
have fitted the pushrods exactly as described in these instructions. The pushrod linkage points
on the servo output arms are pre-defined, so any servo travel adjustment required must be
carried out via the transmitter's electronic adjustment facilities. Please note that servo travel
must not be set at too high a value; the swashplate must not foul the main rotor head when the
roll and pitch-axis stick is at its end-points, as this would mean that smooth collective pitch
control would no longer be possible, since the swashplate could not move any further along the
shaft.
9.2 Main rotor collective pitch settings
The collective pitch values are measured using a rotor blade pitch gauge (not included in the
kit). The following table shows good starting points; the optimum values may vary according to
the rotor blades you are using and the model itself.
Hovering, practice flying
Aerobatics
Auto-rotation
The collective pitch settings are adjusted at the transmitter. This is the procedure:
1. Measure the setting for hovering collective pitch and set it correctly;
2. Measure collective pitch maximum and minimum, and adjust the values using the collective
pitch adjustment facility on your transmitter, following the diagrams shown below:
9.3 Adjusting the carburettor control system
The following diagrams show two possible carburettor control curves:
• The hover-optimised throttle curve produces smooth, gentle control response in the hovering
range.
• The values stated here vary greatly according to the motor, fuel, silencer etc. you are using.
The only means of establishing the ideal settings is to carry out your own series of practical
test-flights.
