Back in late November I had a big crash with my quadcopter, then with the cold season and the huge workload of the new job at the university I never had the mood to fix it..
But, as soon as spring arrived, I had to fly it again. So, I finally been able to spend a couple of nights fixing it and a couple of days ago it airborne again!
Following a small video on one of its flights. I spent a good amount of time on MultiWii PID tuning. To make my life easier I decided to plug on the quad one of my LibreTooth boards so that I could connect it via Bluetooth from my Android phone. There is a wonderful Android app called MultiWii Configurator which allows you to PID tune your MultiWii copter directly from your phone. With this setup, it’s very easy to get to very stable settings.
