"Hi there!
I'm a user of pix4D, creating maps and 3d models. I own an Ebee (sensefly) and 3 mapping multirotors, from small 560 to big octo 800. I need now to use my own map made with an ebee/Pix4D in tower app, to have the benefit of the cm accuracy…"

"Another question about retractable landing gear. When in auto retract/deploy mode, how the pixhawk detect landing? Is that triggered only if landing or RTL mode is switched, or is this something with baro/gps that do the job?
Thanks,

I'm like you, in the dark for setting up my PX4flow.
By testing a lot of things, i finally have a good signal, correlated with Imu signal.
The sonar seems to not be compatible with pixhawk/apmcopter, and i try to solder another one…"

"Hi everybody,
I just upload 3.2 in my carboncore cortex, and i wonder if i can activate ekf "just for try" or is it something to tune before use? 
Thank you, specially to the dev team that did a really impressive work!"

"@Patrick,
My problem was that i have a DccEle - DCcduino Mega 2560, a clone of arduino uno, and the drivers are differents. I finally found them on a russian website, and it works perfectly after little adjustments. Thanks for all!!!"
