EN SAFE® Select Switch Designation SAFE® Select technology can be assigned to any open switch (2 or 3 position) controlling a channel (5–9) on your transmitter. Once assigned to a switch, SAFE select ON gives you the flexibility to choose SAFE technology or AS3X mode while in flight. If the aircraft is bound with SAFE select OFF, the aircraft will be in AS3X mode exclusively.

EN Flying Tips and Repairs Consult local laws and ordinances before choosing a flying location. Getting Started Once on the ground leave the elevator neutral and avoid sharp turns until the plane has slowed enough to prevent scraping the wingtips. Before you fly, range check the radio system. Refer to your specific transmitter instruction manual for range test information. When you first connect the battery to the airplane AS3X will not be active.
