The video below (enable audio!) shows a detailed overview of the new Pixracer flight controller.

It is the 4th generation of the Pixhawk flight controller family (make: FMUv4) and like the first generations designed by the Pixhawk Open Hardware team in collaboration with an international dev team. It supports the PX4 and APM flight stacks. If you like to try PX4 on it, follow the user guide.

I mean which serial port in MissionPlanner to configure to use FrSky instead of MavLink to be able to use the inbuild FrSky support of the PixRacer.

In the schematic it seems that Serial4 is used:

But the inverter is connected to USART8 of the processor:

So I'm wondering, which port to configure in MissionPlanner ( maybe Serial4).

I cannot get APM to work with pixracer. 
I calibrate the compass.  I can look at the parameters in the parameter list in either QGC or MP, and they are there....
But it keeps telling me the compass is not calibrated.   And sometimes, after rebooting, the offsets are actually all gone and back to 0.  But, not always!! 

Should 3.4 alpha be working, or is this just an issue w/ using the alpha software? 
I'm trying to determine if my board is bad, or if it's a software issue. 

And what's strange (to me w/ my lack of info) is that it's only the magnetometer and accelerometer info that gets reset... it remembers my RC config and tuning, etc.  Does that get saved in a different location, or what is up with that?

Well, just try the master of today. Old one used to forget some settings.But well, its alpha.  Arducopter v4 still has quite some flaws and therefore you have to keep on trying. Or move on to PX4 . PX4 stack setup is running fine already.

It does seem better!  still some issues.  
I'll talk about it in the 3.3 beta thread.

Looks nice, Swift ! I´ve been thinking about rubber fan mount screws for vibration damping.

Not ideal, but pretty cheap and there are a lot of different types.

I see. Your solution provides impact protection as well and the Baro foam can be squeezed in between.(One of my favourite topics as well)

Hi all,

I get my pixracer today. it looks good and a wlan module was included.

what I missing are this servo connection pins, where can I get this pins?   

many thanks,

Alex

They are standard Dupont connectors, usually coming with Servos and ESC. See them at the Pixracer Instructions page pics on http://px4.io/docs/pixracer/

An idea when is going to be in stock again?

Comment by Phillip Kocmoud on March 6, 2016 at 8:56am

Cala, Stock level should stabilize by the end of March. A large number of EU preorders will ship out tomorrow.  Then a US batch the end of the week. Followed by more over the next week or two as more boards are tested and certified. Thank you to everyone for their patience.
