SMARTSAfE fAIl-SAfE
The AR6200 features the SmartSafe™ fail-safe system.
SMARtSAFe:
• Prevents unintentional electric motor response on start-up.
• Eliminates the possibility of over-driving servos on start-up.
• Establishes low-throttle fail safe if the RF signal is lost.
• Maintains last-commanded control surface position in the event of RF link interruption.
Note: Fail-safe positions are stored via the stick and switch positions on the transmitter
during binding.

Smartsafe is ideal for most types of electric aircraft and is also recommended for most types of gas- and glow-
powered airplanes and helicopters. Here’s how SmartSafe works.
RECEIvER POwER ONly
When the receiver only is turned on (no transmitter signal is present), the throttle channel has no output, to avoid
operating or arming the electronic speed control. In glow-powered models, the throttle servo has no input so it
remains in its current position.
AfTER CONNECTION
When the transmitter is turned on, and after the receiver connects to the transmitter, normal control of all channels
occurs. After the system makes a connection, if loss of signal occurs, SmartSafe drives the throttle servo only to its
preset fail-safe position (low throttle) that was set during binding. All other channels hold their last position. When
the signal is regained, the system immediately (less than 4 ms) regains control.
