First flight impression: Wow!
The difference in stability was much more than I had anticipated. It feels more crisp, precise, locked in and stable. But I ran into some trouble on the first flight. One of the Hobbyking SS18 ESC’s kept shutting down after 15-20 seconds of flight. After some testing I found that the SS ESC’s do not like the 180Hz update rate of the KK board. The SS ESC’s are programmed to shut down if they receive a incorrect PPM signal. The software recognized the high update rate as a faulty signal and started to shut down. This is a great feature when you’re flying a plane with a FM receiver, but not when you’re trying to fly a tricopter. Unlike sensible people I did not buy three new ESC’s capable of running the higher PPM frequencies, but rather decided to try and modify the SS ESC’s.
