Hi all

A huge amount of effort has gone into this exciting new release of ArduPilot: Copter 3.4.1.

The new features are mostly described on ArduPilot forum blog post but the first few are copied here:

New Features (in alphabetical order mostly):

  1. New boards/frames supported including:
  2. ADSB sensor (from uAvionix) support and FailSafe to help avoid incidents with manned aircraft

  3. Attitude control improvements including completion of move to Quaternions
  4. ACRO_Y_EXPO allows exponential yaw in ACRO mode (coming to other modes soon)
  5. AutoTune robustness improvements especially for larger vehicles (reduce chance gains go too low)
  6. Boat Mode allows easier takeoff from boats

.. and much more!

3.4.1 just added Pixracer PPM input fix

3.4.2 RC1/2 work is already well advanced and will be available shortly, but consists only on small minor improvements.
For some of us that fly small drones the support for the PixRacer is fantastic, and even the new PixHawk 2.1 from ProfiCNC is already supported.

Overall is a great release, with a high degree of professional work by the entire ArduPilot team.
Happy flying, and keep the feedback on the forum
