"@Tridge Congrats on the new release to you and all the developers!  Question about the "fixed 50Hz MAVLink support". Does that mean that MAVLink messages can now be requested/delivered at rates up to 50 Hz?  "

Philip Giacalone replied to Hugues's discussion Is there a Mavlink library or programming API (not python) ? in the group ArduCopter User Group
"Yes, understood, thanks. But there's still a need for an airborne java API, rather than python. Are there plans for this? "
