M4 and Taranis with DM9 module - Roll Channel Problem

Hello,
I have a Taranis radio with Spektrum DM9 module. It works well with my all other receivers ( official and orange rx ).
When I bind to my M4 v2, all channels are ok except for Aileron/Roll ( CH2 ) which jumps constantly between +12 and +64.
When I move the stick the gap increases and jumps between +100 and +300 etc.

This is weird, and it never happened to me before. Any ideas of what can be the reason for this odd behavior? Maybe I'm missing something.


Thanks in advance,

You can try my eeprom.

Hi chestnut,
thank you for your time, but that eeprom contains a model configured for the internal FrSky module.
I'm using Spektrum DM9 module for DSM2, which works great with all my other receivers.


Thanks,

All I can tell you is it works with an Orange DSM module (in a Taranis)... not very helpful, I know, but seems strange that it wouldn't work properly with an official Spekky module. What happens if you map the Roll control to a different channel (on Taranis and AQ)?

I have the same with my DM9, module. :shock:

I though it was defect, but because you have the same problem it must be a DM9 timing problem. :)

Instead i use a home made DX5 module adapter and that one works fine but only 6 channels.

I'll try some remapping tonight, but I don't have high hopes if others like Frank have the same problem.

My alternatives are:
- get another module like the orange and sell my DM9
- put an orange spektrum satellite which works well in my other mini projects

Thank you for your help guys,

Good news!
the problem is gone when I remap Aileron/Roll Channel. Thank you Max for the idea! Tomorrow I'll do some more test, but so far so good. Yeah! :)
