I would love if you had some more details , even for a test case. the documentation refers to a room about 3*6 meters in size, 2.6 meters height. what accuracy can I expect in this case wi...

Re: takeoff issue with the new flow deck 2.0 + HL controller

thank you for the reply. I have been managing with the "contraption" for now, but 1 in 8 takeoffs results in crash. Do you know of an example of transferring from hover commands for takeoff to high level commands for hovering/flight? I know that if high level controller is not enabled, drone will dr...

CF2.0 with flow deck 1.0 and same code takes off properly. I also found that putting the CF on a stand about 80mm from the ...

Re: Multi-Ranger left sensor [FAIL]

thanks for this post! I got 5 multi ranging decks and now testing a new one and it says right sensor failed!
so will try to reflow.

also, I had one multi ranger fail completely, but that was due toa crash, replacing the 0.1" headers to new ones fixed the issue.

Re: Flow deck suggestions

hi! I have a similar issue, when using flow deck and Mellinger controller, takeoff is very unstable, like in the initial moment the drone is trying to fly somewhere else, and then tries to correct. after initial stabilizing, if it did not crash, it flies great. once in a while it takes off normally....
