Receiver type

OMP protocol

OMPHobby M2 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 OMP M1, M2 OMP from the configuration file.

5Throttle Cut/Hold
6Flight mode (Normal/Idle-up1/Idle-up2)
7Attitude Hold (auto level) ON/OFF

SBUS

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 or Radiomaster R81 Nano receiver + SBUS receiver adapter.

Choose model OMP M2 SFHSS from the configuration file.

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 OMP M2 DSM from the configuration file.

Other functions

  • Flight timer: 3.5 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 TX16S.
  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.
Binding

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 and OFF.
  • Keep Auto-level OFF.
  • Move the aileron/elevator sticks and check that the swash plate is moving correctly (left-right and 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.

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.

CurveCurve nameFunction
CV2FM1Throttle curve for Normal mode
CV3FM2Throttle curve for Idle-up 1
CV4FM3Throttle curve for Idle-up 2

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.

CV5CP1Collective pitch curve for Normal mode
CV6CP2Collective pitch curve for Idle-up 1
CV7CP3Collective pitch curve for Idle-up 2

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.
