title_body: Quadcopter rotates too slow When I flew my drone yesterday, all the manoeuvres I did felt really slow. I then went into the OSD and changed the rates a bit. The drone then acted as it should, but when I then changed back it still felt fine.
  
  When reviewing the blackbox logs afterwards I noticed that the gyro only registered around 340 deg/s rotation at full stick deflection (See the last part of the bad blackbox log)
  
  After going into the OSD to change what I said above, the rotation speed was 900 deg/s at full stick deflection, as it should be with the rates I have.
  
  To clarify a bit: It felt like I was using rates that were much lower than they actually were. The problem disappeared when I went in to the OSD menu and out again, but the next day I had the same problem again. It is not a major issue as it is easily fixable, but I would be glad if I could get some help to figure out what the problem could be.
  
  The flight controller uses betaflight 4.1.
  
  Here is a link to the blackbox logs.
upvoted_answer: I think this problem had two different reasons; two screws that held the flight controller were a loose, and there was likely a problem with the connections between the gimbals and mail board on the transmitter.
  The screws that were loose were both on the same side, which caused the FC to &quot;lag behind&quot; the movement of the quad and thus giving false values to the PID-controller. At least that is my theory.
  The problem with the transmitter was not as obvious, but I whan looking at the reciever tab in Betaflight Configurator, I noticed that the roll channel acted almost as if it was smoothed. Even if this wasn't visible in the radio I still tried to unplug and replug the connectors to both of the gimbals, something that was recommended on a few forum threads I found.
