Setup

When setting up your head, adjust the links as needed so that:

Servo arms are horizontal
Swash plate is level
Washout mixer arms are level
Fly bar arms are level
Main blades have zero degrees pitch

This should be done when the radio is switched on, both sticks are centered on your TX and with your pitch curve setup for zero degrees at mid stick.

The above will give you push rod lengths of:

Pushrod	Length
Blade grips to fly bar mixing arms	18mm
Fly bar mixing arms to swash plate	40mm
Fly bar arms to washout mixer arms	24mm
Swash plate to front-left and front-right servo arms	33mm
Swash plate to rear servo arm	29mm
