Inductrix & Taranis, using Spektrum DM9 module

Got lots of money and no patience? You’re in luck, you can get a Spektrum DM9 module for your Taranis quickly, and have it bind to your Inductrix easily.

Inductrix, Taranis, DM9

Unfortunately the module is $59 from eBay, …but it arrives within 3 days and it works.

You’ll need to create a new model on your Taranis, and as shown on the picture below, disable the internal RF module, enable the external RF module, mode on PPM, CH1-8, 22.5ms, 400u, negative polarity.

Inductrix Taranis Model setup

Bind

To bind, follow this sequence:

  • Switch off Taranis
  • Switch on Inductrix and wait for blue LED to flash rapidly
  • Hold down bind button on DM9 module (the only button on it) and keep it held while turning on Taranis
  • DM9 will have a flashing orange LED, then solid orange LED, then go out, now you can let go of the bind button.
  • Blue flashing LED on Inductrix should stop flashing and go solid blue. Now you’re bound.

If the above doesn’t work, keep trying, remove the module from your Taranis and then put it back in and try again. It took me about 5 attempts. At the moment it appears you have to re-bind every time you reboot, but I’m working on a solution for that. EDIT: Appears to be permanently bound now, maybe you have to rebind a couple of times before it remembers?

Channel Direction

My Yaw and Roll channels needed to be reversed within my model setup on the Taranis, there is a nice easy instruction video here: https://www.youtube.com/watch?v=I046G6cW9W8

Timer

Within your model setup on the Taranis you can also add a countdown timer, since the inductrix batteries don’t last long. In Timer 1 choose: THs (throttle start) 3:30 (my conservative estimate), minute call: on, countdown: voice.

Range

If you experience loss of range, open up the DM9 module and ensure the UFL connector is still plugged in. Mine wasn’t, but it still flew!

    It works! Thank you!

    Hi Sam, and anyone else having trouble – just a heads up that in my case, the only way I could get my DM9 module to work with my Taranis / Inductrix was to change the polarity to + tive (with all other settings the same as yours). As soon as I did that, it worked perfectly.
    Thanks for this post! I bought the same module using your link! Works a charm.

    Same here, until I actually changed polarity it didn’t work. I thought I had a brand new module too!

  • Jesse P

    hey man thanks for the shout!! I’m still not getting this thing to work. The orange light on the module will never blink when i’m in ppm mode… what gives??

  • Andrew Schultz

    Hey just thought I’d ask… I can get it to bind, but it is totally unflyable.. it lists in different directions, and I did bind chanel 6 to SH^… is it the expo settings that i have to adjust? it being winter I’m dying to fly this thing around my home!

  • Sam

    Hey Jesse, sorry I missed this comment. I’m having problems binding this DM9 module since I switched to HV lipos, is that what you’re using? Also, did you try switching the polarity as mentioned by others?

  • Sam

    Hey man, did you see what I wrote above about channel direction? Maybe you need to switch that?

  • Andrew Schultz

    I did reverse the channels, but it still is funky.. I guess I’ll screw with the expo’s, unless you guys have any suggestions. Thanks!!

  • Andrew Schultz

    NVM, I got it.. I am rapidly coming to the conclusion that I am just a terrible pilot 🙂 Thanks for your response and your blog 🙂

    Edit: the secret was that Spektrum is roughly 125% of Taranis expo values.. once I dropped it to 80 throttle, and 65 on the rest, it was much easier to fly.

  • Sam

    Nice, thanks for sharing. Are you flying in rate or horizon mode? Maybe you need to switch to auto-levelling with horizon mode?
