• Trim Flight Results - Swash trim offers some benefits when the helicopter is flying upright but it has a negative effect when flying inverted. Since V4 the swash results of the trim flight are no longer applied to the servos and should only be used to assess the helicopter's mechanical setup. The function of the tail trim remains unchanged and it can greatly improve tail stop quality and symmetry. Effectively it automatically achieves the same as mechanically trimming the tail in rate mode. Wind gust will affect the accuracy of the trim flight, thus it should only be performed in calm conditions.
Swash angles over 0.5 degrees are typical when the airframe is misbalanced or the swashplate is not accurately level. We recommend that the cause of such high readings is investigated and rectified. To erase the trim flight results start a new trim flight and then cancel it via the DataPod or simply power off before the trim flight is completed. Note for DataPod users: The letters F, B, R, L indicate the direction in which the Vortex needed to move the swash in order to maintain drift free hover (front, back, right and left respectively). |
| • Start Trim Flight? - To perform a trim flight activate this function and hover the helicopter. Once it is safe to do so, try not to touch the sticks for 5 seconds. Each time you move the sticks the 5 second interval will restart. It is not necessary for the helicopter to remain perfectly stationary as long as it is only moving very slow. Completion of the trim flight is indicated by the Vortex gently stepping up the collective thus causing the helicopter to slightly rise. Wind gust will affect the accuracy of the trim flight, thus it should only be performed in calm conditions. |
| • Trim Flight Aborted - The trim flight function was not activated. However, if it was already running it has remained active. To cancel the trim flight simply power off the Vortex. DataPod users can also cancel the trim flight by pressing the [S] button on the HOVER NOW screen. |
| • Trim Flight Active - The trim flight is now active and the Status light on the Vortex should be flashing rapidly blue. Hover the helicopter as instructed in the previous page. You can now disconnect the DataPod or USB cable. Once the trim flight is competed you can return to this menu to view the results. |
