    UAV "pitcherons"

    "With ailerons the entire wing could be matched to the roll rate" I cant seem to get my head around this, does anyone have an idiots explanation? Thanks

    UAV "pitcherons"

    "With ailerons the entire wing could be matched to the roll rate" I'm not sure I understand this, are you talking about milti-sectioned ailerons, with higher throws towards the tips? Otherwise this may be the bit of understanding I am lacking! Thanks again!

    UAV "pitcherons"

    "Taken as a whole, the wing section with the aileron is changing the camber of the airfoil, which changes it's angle of attack. Like the pitcheron the AoA will tend towards zero, until there is no lift acting to increase the roll rate." Right, but with ailerons, when the AoA gets to zero...

    UAV "pitcherons"

    Interesting, thanks! "A pitcheron vs aileron still has the same AoA change during the roll maneuver. The main difference is the degree of control response for a certain amount of control surface deflection. Essentially a pitcheron is a wing consisting only of the aileron; not a separate case."...

    UAV "pitcherons"

    "Pitching the wings kills the lift" does it? I would have thought that increasing the AOA of a wing would add to the lift (while increasing drag); a similar effect to the downward deflection of an aileron. Of course, a negative AOA would kill the lift, but then that's what you want, at least on...

    Might actually be clearer here, fair warning about the music though... https://www.youtube.com/watch?v=-rGE0Z7zNcg

    UAV "pitcherons"

    Thanks for your reply, I was aware of the wright brothers wing warping, but that wasn't quite what I had in mind. The implementations I saw had a stiff wing fixed via a bearing to the spar, around which the entire wing rotated and the entire wing rotated. see the last few seconds of this video...

    UAV "pitcherons"

    Hi All, As an electronic engineer my knowledge on this subject is rather lacking, so apologies if this is a simple/ridiculous question: I recently cane across some remote control models that had variable incidence wings, i.e. both the aileron and in some cases the elevator functions were...
