0 Binding Spektrum DSM and Turnigy OrangeRX Receivers

Here's how to bind a DSM{2,X} transmitter and receiver.  This applies to both Spektrum and OrangeRX units.

Safety First: Remove your props.  If you screw something up, your motor could unexpectedly spin up at 100% power.  That's an uninteresting problem to resolve.

Setup

• Remove props.
• Power off Rx, Tx.
• Make sure ESC is plugged into the THR port of the Rx.
• Plug bind plug into Rx bind port.  Polarity does not matter.

Binding

• Power up plane.  The Rx LED should fast blink.
• Move Tx sticks into desired failsafe position.  Most importantly, make sure THR stick is at lowest position.
• Press and hold Tx bind button.
• While keeping Tx bind button depressed, power on Tx.
• While keeping Tx bind button depressed, wait for Rx LED to go solid.
• Release Tx bind button.
• Power off  Rx.
• Power off Tx.
• Remove bind plug from Rx.

Testing

• Power on Tx.
• Power on Rx.
• Controls should be operational Fiddle with sticks and adjust Tx settings appropriately.

Testing Failsafe

• Adjust throttle so that motor is spinning.
• Move sticks so that control surfaces are deflected.
• Power off transmitter.
• Motor should stop spinning.  Depending on your Rx model, the control surfaces will either stay in place or return to the failsafe positions set while binding.
• Power on transmitter.  Stick control should resume.

Range Testing

• Attach the model to the ground.
• Move away 90 feet.
• Press and hold the Tx Bind button.  This puts your Tx into reduced power range test mode.
• Ensure all controls work as expected.
