Hovering pitch

When an AttitudeControl mode with pitch is used, you can set the minimum amount of pitch deflection used to keep the heli in hovering position. Ideally the pitch angle is exactly as large as necessary to maintain a stationary hover without ascending or descending - typically somewhere between 5 and 6 degrees. The value shown here is the percentage of the maximum pitch. So if your helicopter is set up with 12 degrees of pitch, a value of 50 corresponds to roughly 6 degrees of hovering pitch. If you want to measure the exact pitch, click the "Measure" button - this will temporarily move the swashplate into the hovering position.

• Please note that during operation you can always add more pitch by giving thrust stick input. The pitch you adjust here is only the minimum amount of pitch, so in case this is not enough to keep the heli in the air, you will always have the option to override the pitch input for safety reasons.
• When using "3D Mode with pitch", make sure the maximum pitch range is symmetrical, i.e. the maximum positive and negative pitch are the same size. Otherwise the hovering pitch will differ between normal and inverted flight, as the AttitudeControl pitch is calculated from each maximum pitch setting! The setting affects both directions - separate adjustment of the hovering pitch angle for each direction is not provided.
• If the maximum positive/negative pitch is changed at SETUP MENU point K, the hovering pitch will change as a consequence! So after adjusting the maximum pitch, also check and readjust the hovering pitch here at menu point M.
• When tilting the helicopter, the amount of pitch will change and you may not see the exact hovering pitch you set. This is because the system uses an internal algorithm that controls the pitch during rotation, trying to roll the helicopter with as little horizontal and vertical movement as possible. This algorithm assumes you've set the hovering pitch as well as possible - so, for example, if you've set more pitch to help the helicopter gain height when AttitudeControl is active, this may prevent the helicopter from turning cleanly on the spot.
