One would have to "play" with the set up to find what results
from this. Would believe there would be some delta effect?
Would that effect be the same as it would be with the blades
aligned to the tang? Or would something weird happen?
Well no actually
If the tang was simply angled forward from an original straight tang position then you would be correct, however the tang is both angled AND moved forward parallel to the centre of rotation. This ensures everything stays exactly in place be it a single bolted blade or a wet noodle !
Colin, you wouldnt be confusing flutter with flapping would you ?? I only ask as when I make really tight turns or heave back on the stick I always get a lovely 'thrumming' noise from the rotors.............all rotorcraft do it.
You know, I actually went flying with a fi...fix........fixe.....( ahem) fixed wing model yesterday and dispicable though you might think of me I actually enjoyed it ( waits for scornful remarks)
