| • Trim Flight - Performing a trim flight is not essential but it can be a valuable tool in assessing the helicopter's mechanical setup. Whilst the results of the trim flight will apply the required corrections automatically it is best to improve the mechanical setup of the helicopter so the trim flight result can eventually become insignificant and be erased. Performing a trim flight - Wind gust will affect the accuracy of the trim flight, thus it should only be performed in calm conditions. Activate the trim flight 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. Making sense of the results - 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). 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. Erasing the trim flight results - Start a new trim flight and then press [S] to cancel it.
