11.1. Channel assignments

[Note]Note

The channel assignments are determined by the transmitter, not the receiver. For example, when using a Futaba transmitter with a JR negative shift receiver, you must use the Futaba channel assignments.

11.1.1. Futaba/Hitec transmitters

If you have only two servos controlling your swashplate (with either non-CCPM or any CCPM) then the channel assignments are:

  • channel 1: left/right (roll) servo

  • channel 2: front/back (pitch) servo

  • channel 3: throttle (ESC)

  • channel 4: gyro control (tail servo or tail ESC plugs into gyro)

  • channel 5: gyro sensitivity (optional)

  • channel 6: collective pitch servo (for CP helicopters such as Shogun)

If you have three servos controlling your swashplate (either non-CCPM or any CCPM) then the channel assignments are:

  • channel 1: right (roll) servo

  • channel 2: front/back (pitch) servo

  • channel 3: throttle (ESC)

  • channel 4: gyro control (tail servo or tail ESC plugs into gyro)

  • channel 5: gyro sensitivity (optional)

  • channel 6: left (roll) servo

11.1.2. JR transmitters

If you have two servos controlling your swashplate (either non-CCPM or any CCPM) then the channel assignments are:

  • channel 1: throttle (ESC)

  • channel 2: left/right (roll) servo

  • channel 3: front/back (pitch) servo

  • channel 4: gyro control (tail servo or tail ESC plugs into gyro)

  • channel 5: gyro sensitivity (optional)

  • channel 6: collective pitch servo (for CP helicopters such as Shogun)

If you have three servos controlling your swashplate (either non-CCPM or any CCPM) then the channel assignments are:

  • channel 1: throttle (ESC)

  • channel 2: right (roll) servo

  • channel 3: front/back (pitch) servo

  • channel 4: gyro control (tail servo or tail ESC plugs into gyro)

  • channel 5: gyro sensitivity (optional)

  • channel 6: left (roll) servo

11.1.3. Multiplex transmitters

The Multiplex Evo transmitters can also use the Futaba or JR channel assignments instead of the Multiplex channel assignments.

If you have three servos controlling your swashplate (must be CCPM) then the channel assignments are:

  • channel 1: right (roll) servo

  • channel 2: front/back (pitch) servo

  • channel 3: gyro control (tail servo or tail ESC plugs into gyro)

  • channel 4: left (roll) servo

  • channel 5: throttle

  • channel 6: gyro sensitivity (optional)

11.1.4. Airtronics/Sanwa transmitters

If you have only two servos controlling your swashplate (either non-CCPM or any CCPM) then the channel assignments are:

  • channel 1: front/back (pitch) servo

  • channel 2: left/right (roll) servo

  • channel 3: throttle

  • channel 4: gyro control (tail servo or tail ESC plugs into gyro)

  • channel 5: gyro sensitivity

  • channel 6: collective pitch servo (for CP helis such as a Shogun)

If you have three servos controlling your swashplate (must be CCPM) then the channel assignments are:

  • channel 1: front/back (pitch) servo

  • channel 2: right (roll) servo

  • channel 3: throttle

  • channel 4: gyro control (tail servo or tail ESC plugs into gyro)

  • channel 5: gyro sensitivity

  • channel 6: left (roll) servo
