Another video from the same place. This time my Nighthawk 250. I always had lots vibration and jello in this quad, but so far I was still working on the setup. After testing different propellers I found that 5040 produce the least jello, but the break when you look sharp at them, so I tested 6030 carbon now. Jello and vibration better, but not good. One motor axis is lose, this will be the next test (motor replaced meanwhile). Now TxPID and Easytune is setup, so I will do a few tuning session soon.
