Hey DJI-

Over on the Facebook page, we've been discussing some weird D.Bus/S.bus compatability issues with the Ronin, and think we've narrowed it down to a firmware issue on the Ronin side.  

Here is the discussion link with video:
https://www.facebook.com/groups/RoninOwners/806245072782262

In short, when using the D.Bus port of the Ronin connected directly to the S.Bus port of a FASSTest r7008SB receiver, the ronin seems to stutter every once in a while, where it completely locks up, then jumps back to life.  It seems like it works fine with the receiver in 12ch mode (vs the normal 14channel mode that has 2 extra digital channels in the S.Bus stream).

Any way to make a firmware tweak on your end to make the ronin better ignore those two extra digital channels?  Using the FASSTest 14channel receivers we have access to telementry giving us voltage feedback and dual receiver capability (which is extremely important for any fully remote ronin application like a ronin on a cablecamera), but this unpredictable stuttering is really a bummer.

DJI? any insight?  Definitely a compatability issue between FASSTest 14ch and ronin- FASSTest on 12ch mode works fine.  Must be in the two digital channels causing the ronin to choke.  Would love to have this fixed to use telemetry and dual receivers!

For some reason I know that the Futaba has a weird PPM signal when you use the 14 channels but that goes away with 12. I know that the Spektrum remotes have a terrible PPM signal so don't even go there with a Spektrum, stick with the Futaba for the best PPM out.
