Step 04: Cyclic calibration

The goal of this calibration is for the VBar to know approximately how much deflection is required for a certain reaction. It is NOT the cyclic deflection in flight - but a value that describes the cyclic geometry.

The prerequisite is a statically correctly adjusted (rotated) swashplate as explained above. We can only measure this if the blade has the maximum aileron deflection perpendicular to the direction of flight.

Video: Setting up the swashplate on a scale heli - from 5:04 until 6:45 it covers the 8 deg cyclic setup
 

If the swashplate (e.g. follow-up check at some point) has already been further optimized during flight (rotated differently from the previous 90° setting), please either temporarily take it back or zero and measure at the point in the rotation with the greatest deflection.

Since the swashplate tilts for aileron when the button is clicked, we have to ensure that the blade we are measuring on also shows 0° on the gauge at zero pitch - and that we also get the maximum deflection.

So we should call up the "Trim" menu (all blocked at zero colelctive) - place the blade over the tail and zero the pitch gauge.

 

 

We set the check and take a look at the swashplate. The blade remains there during the entire measurement.

 

Now we have the result and can set it to about 8°. Ideally, this should result in around 80...110 points.
