Thanks again toall the devs, just come back from a roadtrip holiday with our SteadiDrone QU4D and H6X, flying 2.7, and no issues at all. Just loaded 2.7.1 onto our big SteadiDrone EI8HT and test lifted 8kg, flies perfect :)


Will post some videos and images soon.

I wait your videos, bests bro!

Hi all,after a loooog break i am trying to connect via MP to my 2560 board with no succes (the board has not been previously used).Another way to upload firmware, if i rememner well was via Arduino but i cannot find some instructions, can someone give me a clue ? A video tutorial will be great. Thank you.

Alex, you need to load the firmware before connecting. Just click on the vehicle type you want in the firmware screen.

Chris, many thanks, it is working now.

I have made the first trials and it appears that if i arm the motors and i do not move the sticks for around 25 seconds the motors will disarm automatically. Is this a new safety feature installed or i have some issues ?

Yes it is. That's a safety feature active since version 2.2 or so.

Yesterday night i've made a first flight with the default parameters, no wind. In stable mode it is working ok, in Loiter mode it is moving left/right , forward/backward also from time to time (at 3 sec aprox) it is shaking, like an over correction.I've attached all the log files from the flight.  Assigning CH6_LOITER_KP to a knob could help me to improve the behaviour ?
