Made a slight improvement in efficiency. Now I don't have to worry about the props taking out a wire or hitting the frame.
You've been through quite a lot with your drone, it's quite a journey! P.S. They can also feel a bit more responsive with smaller props that have a spin faster for the same lift.
I have five drones, but this is the only one that I made from scratch, and it is also the most fun for me to fly. I still get too nervous flying the massive hexacopters I built. my flying is all about slow and steady. Those racer guys are amazing. For me it's all about video and photography.
