I did put together all copter parts this weekend. From technical point of view it`s ready to fly and I will add next week only one part – small LIPO protector. I designed it on Friday but still I`m waiting for delivery. Propellers protectors are removed also and I did order 10 pairs of additional propellers during Aliexpress promo days - 11.11. I hope I will receive it soon.

There will be no more changes for this part. Everything is well connected, all computer parts like camera mount or telemetry cable are additionally protected by hot glue.  I lost a lot of time to complete it but I do not want to have any unexpected problems related technical connections future.
I did change too much for this phase to think more about connections problems :)

Px4pro firmware configuration is almost done ( frames, gyro, compass, flying modes etc ). I spent some time also to check a new flying modes because they are little different that autopilot have.

Still I`m trying to understand how to setup virtual joysticks and failsafe options. 

I`m not clear with two important failsafe tiggers that are available in PX4 firmware and I don’t know how to configure it using Qground Control software yet. There first one is called: “RC lost” and second “datalink lost”. Seems they are working in different way that I was thinking before and this is the most important for me to clarify it.
I hope I will find answers writing some posts to px4 developers next week.
