This was a perfect day for finally trimming out the UMX Radian; a nice soft breeze and sunny, blue skies... and this video is a compilation of these trimming experiments. This little confection has always, we felt, underperformed and been a finicky little thing. So, the obvious place to start was with some nose weight. If you cut it open, there's a space up front under the 'canopy' that almost seems designed for a 5g iron weight. We think HH should put that in at the factory as it now flies beautifully.
