Howdy, fellow freaks! :)
Today, I grew bold and wanted to test the behaviour of the blade, when the flybar-weights are being moved toward the center.
What I imagined is, that it would grow more agile, but also more unstable, since the centrifugal mass is being reduced.
But I was *very* astonished indeed, when after moving the weights all the way inboard, I figured that it became indeed more agile, but also more stable...
While it almost actively tended to break out to any side before, it now tends to be more stable, only gusts can make it drift...
In fact, now you can remove your hands from the controls, clap easily twice and then resume steering, while before, removing the hands just momentarily was impossible.
So actually, from what I see, it appears that the rotor's mass has been increased in terms of stability and decreased in terms of agility...
Which are two things that are contrary to each other...
Which makes me and my pal wondering, whether maybe we got something taught wrong at basic school or...
Or what...?
Anybody there that can make sense out of it?
My best guess is, that before due to the weights, there was precession involved whenever the rotor's disk was turned in any way. Now with the weights reduced, that precession is also being reduced, which makes it more stable.
We are all ears for any ideas on the point...
