"They have known about this issue since Feb 2011, but no action, QA is a mystery at 3DR. Great blog by Users, DIY QA too. "
Willem replied to Chris Card's discussion Pitot Tube Question"Just got in to this, mine came last week from 3dr, and guess what, yep just the same.
Whats irritate me is that 3dr knows from this faulty pitot tubes, and still go on selling them to every one.
I do not call that a good service at all!
Thanks for…"

Chris Card replied to Marc's discussion Arduplane 2.70 Altitude failure in the group ArduPlane User Group"I flew my Skywalker with APM 1.4 hardware + V2.70 firmware last Tuesday and it seemed to be holding altitude.
In fact 2.70 did quite well, better than me on manual mode, considering the wind was 7 m/s gust to 11 m/s."
Profile Information
- About Me:
- I have recently re-ignited my interest in R/C airborne craft.
I think it was the FPV & AP systems that hooked me.
II work in special effects for film & T.V.
I'm no longer a kid but I still enjoy R/C boats and planes, model rockets.
I also like photography, boating (being around water), motorcycles & electronics.
- Tell us a bit about your UAV interest
- I am interested in doing aerial photography.
It is my hope be able to map with photos, [for example; The area around a lake], from different directions to produce a "street-view" 360 Deg PAN -TILT etc. Maybe use it to show seasonal changes over an area.

New Firmware for XBeePro900
Posted on January 5, 2011 at 10:46pm 7 Comments 0 Likes
I just noticed that there is a new firmware available from DIGI for the XBeePro 900MHz radios.
The new firmware #1061 has added a choice for 1 or 2 stop bits for serial I/O.
New sleep functions , could be useful ground-side but not likely needed.
There also are some new network node functions.
There are 3 more diagnostic commands and there are functions for I/O sampling.
I haven't read though the updated manual, yet, but I hope to get to this weekend if the weather… Continue
