Dynam 1500mm P-61 Black Widow test flight 03-09-19 GSWAM
« on: March 12, 2019, 12:47:07 pm »
The first flights of this bird were unimpressive....the elevator incidence is off due to the booms downward angle - a factory fitment issue.  It really needs to be adjusted by cutting them off and wedging them up for the correct angle lines with the main wing.  The resultant of the elevator incidence is constant hunting whereas the aircraft gently slowly pitches up and down thus impossible to fly flat and level.  I shelved it away for months and decided to break it out and try some tweaks.

One was to deploy a bigger heavier battery and second was to dial up the stabilizer gains of the pitch axis.  The results are very positive as the model now flies nice and level even in choppy cross winds.  The hunting is gone as long as the stabilizer is engaged.

Here is the video from Saturday 03-09-19 at the field:
