My second flight. I was less nervous, but still fly GPS mode only. It locks neatly in place and keeps steady no matter what. Flying circles finally looks like flying circles. One landing was a little bit rougher than expected, but props are fine.
Change of frequency on the Video TX did not change the poor performance, reception is lost in 20 meters. I will have to try a different transmitter.
Counter on the RC transmitter clocked 7:48 minutes of (relative) full throttle, which gives around 15 minutes of flight time. Still the pack had 10.8 V left.
My first FPV flight went smoother than expected. GPS lock immediate, flight time around 10 minutes with 3 minutes power to spare. However, there are kinks to iron out: FPV ground station is too heavy and keeps tilting backwards and more importantly, video feed breaks after 20 meters or so despite cloverleaf antennas. Will try different channel and different TX location.
