Been testing out the QQ190 -- thanks to DR1 and Quad Questions for providing it not only for the Drone Tech show, but also for BulbufetFPV. I didn't like it at first because of the way that they put a tune on it, but the more I've played with it and the more I've refined the tune to my personal style, the more I'm liking it. Oh -- it also comes conformally coated, so it's very easy to keep it waterproofed.
