I have what I think is a pretty basic question, but is still unknown by this relative newbie. In allthe different R/C helis out there of different shapes and sizes, I've noticed something that seems to not be unique to any particular type - the location of the flybar. Why are some above and some below the main rotors? Is it similar to the difference between a wing-over plane and a wing under one?
Hi HelisRule- Yes and no. Stability and instability explains how the linkages are connected to the flybar. Some helis are set up for stability such as F3C manuevers, some are set up for instability such as 3D and also somewhere inbetween. Hiller is somewhat stable, bell-hiller is less stable and will respond faster to input. There is a column called
FredFiles in the Sept/Oct '07 issue of
MHT (Model Heli Technique Magazine) that discusses flybar paddles. It also refers to the different types of rotor head geometries. Maybe someone else could chime in with a better explanation. I'm a beginner myself. Ask lots of questions and read, read, read. Hope this helps...
