Receiver type

OMP protocol

OMPHobby M2 EVO and M1 EVO OMP comes with built-in receiver that supports OMP Protocol. In OMP Protocol, the throttle curve is fixed in the helicopter and cannot be adjusted at the Transmitter Radio. OMP protocl supports telemetry for Helicopter battery voltage. Normal, Idle-up1 and Idle-up2 flight modes are assigned by a switch on the Radio transmitter.

Choose model EVO OMP from the configuration file.

Channel	Function	Direction
1	Aileron
2	Elevator
3	Collective Pitch
4	Rudder
5	Throttle Hold
6	Flight mode (Normal/Idle1/Idle2)
7	Stability mode (ON/OFF)	Inverted

Futaba / S-FHSS

The helicopter supports one one SBUS port. You can connect a SBUS compatible receiver to this port. It will override the internal OMP receiver. e.g. OSHM2055 S-FHSS micro receiver

Choose model EVO FUT from the configuration file.

Channel	Function	Direction
1	Aileron	Inverted
2	Elevator
3	Throttle
4	Rudder	Inverted
5	Stability mode (ON/OFF)	Inverted
6	Collective Pitch

DSM

The helicopter supports one Spektrum DSM Satellite port. You can connect a Spektrum satellite receiver to this port. e.g. DSM2 / DSMX nano Satellite receiver with bind button.

Choose model EVO DSM from the configuration file.

Channel	Function	Direction
1	Aileron	Inverted
2	Elevator
3	Throttle
4	Rudder	Inverted
5	Stability mode (ON/OFF)
6	Collective Pitch

Frsky D16 protocol (Archer Plus RS mini / R-XSR)

The Archer Plus RS mini receiver is perfect for M1 and M2 helicopters due to its compact size. It even comes with the correct adapter cable.

Note that R-XSR receiver supports 2 modes on SBUS out pin (SBUS mode and CPPM mode). This pin should be in SBUS mode to work with M1/M2 helicopter. The blue LED is turned ON for SBUS mode and OFF for CPPM mode. Press the bind button for 4 seconds to switch between the two modes.

Choose model EVO XSR from the configuration file.

Channel	Function	Direction
1	Aileron
2	Elevator	Inverted
3	Throttle	Inverted
4	Rudder
5	Stability mode (ON/OFF)
6	Collective Pitch	Inverted

Radio switch Layout

Function	Switch
Throttle hold fail-safe	SE (↑Throttle cut disabled, ↓Throttle cut)
Throttle hold switch	SD (↑Throttle cut disabled, ↓Throttle cut)
Flight mode switch	SB (↑Normal, -Idleup1, ↓Idleup2)
Rescue switch	SF (↑Normal, ↓Rescue)
Stability mode switch	SA (↑Self-level OFF, -Self-level ON, ↓Self-level ON)
Volume control	S2 Knob
Brightness control	S1 Knob

Other functions

• Flight timer: 4.5 mins, Haptic countdown at 10 seconds
• To reset flight timer, both Throttle hold switches should be in Throttle hold.
• Voice call on Throttle cut, Throttle active, Flight modes and Stability mode.

Binding and pre-flight Check

Binding

1. Ensure batteries of your Helicopter and Transmitter are sufficiently charged
2. It is a good idea to remove the main and tail blades of the helicopter to prevent any injury if motors start accidentally.
3. Choose the correct model on the Boxer.
4. Ensure throttle hold is engaged.
5. Plug in the battery into the Helicopter and wait for beeps.
6. Press and hold BIND button on helicopter. Blue LED will start flashing. Release the BIND button.
7. On the Radio, go to Model setup. Press MDL button
8. Scroll down to INTERNAL RF section
9. Check that the RF Protocol is selected. If not you have chosen the wrong model.
10. Press the BIND button
11. During binding process, the Blue LED will flash rapidly. Once binding is complete the Blue LED will be steady.

Pre-flight check

• The Red LED indicates Auto-level mode status.
  Red LED blinking = Auto-level OFF.
  Red LED steady = Auto-level ON.
  Toggle auto-level switch and see it is switching between Auto-level ON ja OFF.
• Keep Auto-level OFF.
• Move the aileron/elevator sticks and check that the swash plate is moving correctly (left-right ja front-back)
• Move the collective pitch stick and check that the swash plate is moving correctly (up & down)
• Disengage both throttle hold and throttle hold fail safe switches, give some collective and check that main rotor is spinning.
• Engage any one throttle hold and check that main rotor stops.
• Engage both throttle holds and check that flight timer resets.
• Now you can put the rotor blades back on and do a test flight. Good Luck!

Model Customization

You can customize the model configuration as per your linking. Please refer to explanation of different settings.

Switch Assignment

To change the switch assignments Navigate to Model->Input Page

Scroll to the Function whose switch you want to change. e.g. To change rescue mode switch scroll to Rsq input. Press and hold the Scroll wheel and select EDIT.

Scroll to Source and press the scroll wheel button. Then scroll till you find your desired switch. Press the scroll wheel button to confirm.

Throttle curves

For OMP Protocol, there are no throttle curves on the Radio Transmitter as throttle curve is fixed inside the Helicopter. For other protocols, the below curves are used.

Curve	Curve name	Function
CV2	TCn	Throttle curve for Normal mode
CV3	TC1	Throttle curve for Idle-up 1
CV4	TC2	Throttle curve for Idle-up 2

Throttle curves

Pitch curves

For OMP Protocol, there are no pitch curves on the Radio Transmitter as pitch curves are fixed inside the Helicopter. For other protocols, the below curves are used.

Curve	Curve name	Function
CV5	PCn	Collective pitch curve for Normal mode
CV6	PC1	Collective pitch curve for Idle-up 1
CV7	PC2	Collective pitch curve for Idle-up 2

Pitch curves

Dead band curve

OMP Helicopters have some deadband at center stick at Aileron and Elevator. The dead band curve is mixed with Aileron and Elevator controls to get rid of the dead band. Curve CV12 (DBD) is used as dead band curve.
