Initially the Status LED will be off, the swashplate will be leveled and rotorblades will have 0 degrees of pitch. Attach your pitch gauge at the rotorblade or blade grip, calibrate it to 0 degrees and then tap the aileron stick once. This will move the rotorblade into measuring position. Now check the pitch gauge, we want to see exactly +-6.0 degrees. By rudder stick input you can increase/decrease the amount of pitch (left = decrease, right = increase). You can switch back and forth between measure and zero position as often as you like. When done click the button to proceed to the next menu point.<br />

If your helicopter is too small for attaching a digital pitch gauge or simply in case you haven't got one you can use a little trick to measure the pitch anyway. You can calculate the angle from the distance the rotor blades move from zero position. Actually this is not so accurate as measuring with a pitch with a digital pitch gauge but it's better than nothing. All you need for this is a ruler and and exact eye. First you need to know the length of the rotorblades from the bolt hole to the outer edge. Usually this matches the specified rotor blade length of the manufacturer. Then you align the rotorhead with the longitudinal axis of the helicopter and fold both rotorblades to one side (as this will put heavy load on the servos it is not recommended use this method on large helicopters with heavy blades!). Now hold your ruler to the blades and mark the zero position. Then when you go into adjustment position the rotorblade will move up or down a few centimetres. This distance can be transfered into degrees of blade pitch using the mathematical formula of sinus. Or the other way round you can calculate how far you rotorblades must move in order to get 6.0 degrees of blade pitch.<br />
