Enhanced courtesy of the new SAFE technology that takes 6-axis stabilisation technology to a whole new dimension to provide an on-board safety net that's with you every step of the way. SAFE is designed to help limit the response envelope that the airplane can otherwise be placed into by over control caused by pilot input. With SAFE technology, the novice pilot can learn and grow accustomed to the flight control responses as the technology limits the bank angle or the climb or descend rate within preset limits regardless of the transmitter control inputs.
