Or if you use your deviation Tx as trainer on another radioPhracturedBlue wrote: Only in the case you need an external module may you need to tweak the values.
I've just tested my Devo 10/Deviation (release of last saturday #a8d0315) as trainer on my WK2801 (as master) ...It works, I've just to trims the zero of all channels which are away from the good value.

Now PPM output can be tweaked for different PPM-FM module, below is test result to generate PPM complied with walkera's TXPhracturedBlue wrote: I implemented a config option in the code.
the default is set to match the devo10's normal output.
I also added support for more than 10 channels, though I'm notsure it will actually work.
Let me know if you have further issues. It works fine in Phoenix
As different TX vendors use different setting for PPM output, e.g. Futaba's PPM settings are notch=300us and center+notch=1.5ms, there is no actual PPM standard. I might let the Frame pulse width be configurable between 20000 and 22500m
