Preflight Checklist
•
Mechanically Center Control Surfaces – verify that with trims neutral, servo arms are centered. Then with AS3X/SAFE inactive, mechanically center the
control surfaces by adjusting the linkages. For optimum AS3X performance the goal is minimal amount of subtrim, zero is preferred. A small amount of
flight trim is acceptable, adjust linkages after first flights if trim is excessive.
•
Test controls for correct response to stick inputs – If you are using an out of the box PNP model with no change in hardware, the presets will function
properly, but it is always a good idea to confirm these movements before every flight. IF they are incorrect, please refer to the channel assignment
diagram above and ensure your servos are plugged in as designated.
•
Check servos for binding – Move your controls to their maximum throws in each flight mode/mix and observe the servo arms and linkages. If binding
occurs; ensure the servo arms and linkages are installed properly per the instruction manual. Use additional tuning of the Absolute Travel Menu to
restrict movement of controls if binding is occurring. (This has been performed on our Model Presets BUT it can occur from variations to your servo arm
positions, control travels, and sub trim settings)
•
Take your time to understand what each switch position does – One great tool to help prevent confusion in flight is the Audio Events menu. Use this
menu in your Spektrum transmitter to have your transmitter announce the mode and switch position with a recognizable phrase or sound. (Audio Event
menu not available on DX6e or DX8e)
•
If using Smart SAFE/AS3X Receiver Model Presets, access the Forward Programming menu and perform the following:
▪
Select Relearn Servo Settings to ensure the receiver records your transmitters servo settings
▪
Adjust Receiver Orientation setting to match the position of your receiver via the Orientation menu
▪
Test SAFE/AS3X modes for proper control corrections – If these are incorrect, repeat receiver orientation setup and relearn servo
settings function.
•
If you have setup Thrust Reversing via the Avian Prog menu or with the Spektrum ESC Programmer:
▪
Ensure that the Channel and Switch you have selected is NOT occupied by another function
▪
Check motor for correct rotation in correspondence to your assigned switch – If this is incorrect or not to your preference, simply
reverse the channel in the Servo Setup menu
