Vortex with Spektrum

The last few days I had two or three customers which came in all with the same question. How can we use our DX8, DX9, etc. Spektrum transmitters to fly the Immersion RC Vortex?

While the answer seems easy and Immersion RC is providing a Spektrum PPM Cable for the Vortex, the setup can be a bit cumbersome for those who did not previously worked with the Spektrum receivers which have satellite receivers connected.

We prepared a few minutes video which explains the procedure in detail, but for those who like the written instructions better, here is this post to explain what to do.

  • Create a new model on the DX 7,8,9 etc. transmitter.
  • Grab a bind plug.
  • Grab an AR7000 or similar receiver which can accept a satellite receiver connected to it and of course an external satellite receiver.
  • Grab an 4.8-5V receiver battery, so you can power the receiver/satellite combo.
  • Grab a standard servo which you will connect to the RC receiver’s Aileron channel to ensure it is properly bound.
  • Get the Spektrum PPM cable for the vortex from the above link.
  • Remove the propellers from the Vortex
  • Get an FPV monitor, or a pair of Fatshark goggles to be able to see the video signal from the Vortex during setup.
  • Once everything is prepared you can follow the procedure below to set the Vortex up.
  1. Plug in the satellite receiver to the AR7000 and install the bind plug.
  2. Turn on the Spektrum transmitter (DX7, 8, 9 etc.) while holding the bind button down.
  3. Release the bind button and wait till the bind process is completed. Power both down, remove the bind plug, install the servo to the aileron channel and power up. Move the aileron stick ad ensure that the servo is moving.
  4. If all tested well, power down, remove the satellite receiver from the AR7000 and put those aside.
  5. Install the Spektrum PPM cable into the Vortex, into the same place where the original PPM cable was installed. Pull that out carefully and plug the Spektrum PPM cable in instead.
  6. Connect the satellite receiver to the Vortex, power up the monitor or goggles and your Spektrum Transmitter.
  7. Ensure that your propellers are removed and plug in a battery to the Vortex.
  8. Check on the initial setup screen that the sliders follow your stick movement. If something seems reversed, you might need to reverse that channel in your radio.
  9. Complete the setup procedure, install the Spektrum satellite receiver permanently with a piece of double-sided tape to the back of the Vortex and test if your motors are spinning properly after the arming sequence.
  10. If all is correct, power down, install the propellers in the correct order and you are ready to fly.

One important note worth mentioning before I let you watch the video. The Spektrum satellite receiver is not a full range receiver. While it will give you reliably good signal within a 2-300 meter radius (8-900ft) that is all considered within line of sight and not in an obstacle environment. If you fly between bushes, trees, expect signal degradation after 80-100 meters.   

Now, if you wish, please watch the video below which will explain the same thing once more.
