Hi guys,
The new revision - AUAV-X2 is ready. I performed all tests today - flashing bootloaders, flashing firmware, configuration, sensors test, receiver test, airspeed sensor test, servo tests, power tests, log tests, temperature tests, etc. It seems the "IRON" AUAV-X2 performs just fine. More pictures will follow.....
Nest week I'll fulfill all current preorders.
Best regards
Nick

I suppose nobody is using the AUAV-X2 with UHF (433Mhz) RC.
I bought a AUAV-X2 recently. I really like it's small size.
It's only got one drawback tough: it's very noisy on the UHF band, so forget using UHF-RC with it.
The Pixhawk by comparison is very quiet on the UHF band. It was my intention to use UHF RC and 1.3Ghz A/V, so that turned out to be a bummer :(
I measured broad UHF noise in the range of -75dB close to the AUAV-X2, and around -85dB at around 25cm (where my RC antenna should be). A UHF RC system can't just hop around it because the whole noise floor is raised (it's not just a few spikes).
Anyway, below are some photos of my board. I used coloured header pins because I don't trust myself to plug things in right every time. When using vertical header pins, one has to file/cut little gaps into the header pin plastic because there are tiny components (probably resistors) on the board where the header pins go. The case I use is from Shapeways.
Size comparison between Naze32, AUAV-X2, and a Pixhawk:

..and the case from Shapeways:
Hopefully future versions won't be noisy on the UHF band. If so, I'll definitely buy more.
@Patrick: I fly Arducopter, latest version 3.3-rc1,using Mission Planner (Not APM Planner!) without any probs, as I posted already @ the related thread. You won´t find too much people using QGC with native stack.
@Steven, usually Altitude stability probs are related to light , propwash (wind related), since the MS5611 Baro sensor (same as PIXHAWK) is very sensitive, so its strongly recommended to cover it with black Hi Density foam. Vibrations are an issue too, if the damping doesn´t work as required.
No big deal, Patrick. As you see in the 3rd and 4rth pic above its easy to connect a 3DR Telemetry Radio @ SER1 or 2. So you can use Droidplanner for Android radio Groundstation e.g. for Waypoints / Floow me what ever or Mission Planner for PC better for tuning or callibration apps.
At the pic below, you see my radio mounted @ the bottom of the F450 frame, and my Phablet mounted on my RC Tx.

Yes, its a nice small size PIXHAWK replacement. Works great. No reason to buy a chinese clone anymore. I created some quick start pics for it, which might help.

Steven, Thanks for the feedback. I adjusted the wording on the US site. Several users have their preordered boards already in hand. As of today, over half of the preorders have been shipped. Nick is fulfilling all preorders prior to sending me any stocking units. So if you order at this time, Nick will ship the order directly to you. Once I have them here, I will be able to ship directly from Chicago. We have plenty of stock in this initial batch.
Oh, no @ Steven G, I was not pointing any fingers at you... you just asked why the mods on DIYD forums were so sensitive, apparently in reference to the earlier banter back and forth on this thread.
And the comment about RCG was meant as a separate light poke at another site, one that you chose to compare this community to, and one that moderates in a different way, as you pointed out.
@Steven, I do not understand Sgt Ric's comment was in reaction to your post. About rcgroups I find it impossible to express different opinions without offending some "high" guys who think they detain the truth.
We do not allow personal attacks.
Disagreements and critiques are fine, but they must remain civil.
And really now, why on earth should we aspire to emulate RCG?
