Flight problems after being dormant

Posted by Andy Theimer on April 4, 2014 at 8:48pm

I've been flying for a while but have not had much time of late so I left my APM 2.5, 2.9 firmware 3dr quad sitting on the shelf for several months.  I took it out to fly the other day and on doing my typical preflight I noticed that the quad wants to start rotating to the right as soon as it gets enough power to leave the ground.  I have aborted flights, upgraded firmware, re-calibrated but no luck.  Just at the point of takeoff the quad starts rotating to the right.  I did notice on my last test spin-up the fron-right motor was making a bit more "clicking" nothing that I would consider terribly out of place but its all I have so far?  

Any tips on what to look into in this situation?  Not sure what logs to look at, throttle looks fine, all the accels and compass settings look normal but I'll continue to research.

If anyone has a tip I'd be most grateful for any thoughts, thanks!

    Frist try erasing or reseting and then reload your firmware. Make sure to save your parameter file and do a compare to only reload only what you need. If this does not fix it, try turning on motor logging and see if one motor is causing your issue. Another option is to move motors or ESCs around and see if the problem changes. This will tell you that it is most likely a motor or ESC that is causing your issue. Good luck and fly safe.
