I have recently added the Flysky telemetry module which, although I have not got around to using all the possibilities, has the great bonus of beeping at me when it's aproaching the edge of its range. I am using this system with the APM 2.0 to great effect.
As others have reported the quality might not be as good as some of the better transmitters but, despite that, it's the best I have used and has not let me down in any respect in over a year of use.
If there is a "bleed over" of controls it's probably due to a too wide pulse width on one channel. This can be checked in the APM Mission Planner under "Configuration" and the button that checks the flight functions (ie stabilise, auto etc). Another coment was that the back light was not working; this needs to be turned on in the set-up page of the ER9X firmware.
I am now using Open9x firmware which seems to have added options over the excellent ER system - http://code.google.com/p/open9x/ its worth a check.

I was asking about 9xr ... which already has programmer board etc. fitted.
My 9x's - I have 2 - are stock firmware and I'm happy to leave them that way ... I plan to empty one for reverting back to FlySky module for my WLtoys helis ... and the 9xr to replace it as fixed wing general.
