"Hi Remzibi,

"One thing to try is disconnecting the GPS to make sure it's serial interface isn't interferring with the airborne XBee.

David Sprague commented on Chris Anderson's blog post ArduIMU now available!
"Hi Jordi,

Just to check, you meant 50Hz not 50MHz for DCM update rate. Did you arrive at that refresh rate to be compatible with the radio/servo PCM refresh rates or is that limited by the processing power you have available for the DCM…"

David Sprague commented on Jordi Muñoz's blog post ArduStation Assembly Instructions
"I"ll try the idea of using the Tx line and post what I find out.
