  • I'm at an early, early stage and thus far planning to use something throughly disposable like the Wing Dragon for my own initial training and something from Multiplex for my first UAV airframe when I get to that stage. I've just picked up a book which may be of interest though - "Model Aircraft Aerodynamics, 4th Edition" by Martin Simons (ISBN 1-85486-190-5). I'm no expert, but it appears to be both fairly comprehensive and intelligible.

    The Twinstar is a wonderful platform especially when made brushless. Long threads about that over on RC Groups.

    I love mine.

    Only wish they would make a slightly bigger one!
  • >It's 4 Channel, and foam. I can't find any info on it.
    usually a good sign to wait until you can find any info on it ;oP

    check here for what I think might be on target as regards a Predator

    Why not go with the EasyStar and mod the ailerons yourself?
    There are plenty of how tos out there.

    But my own opinion is that if you intend to put payloads on something that only weighs 500-700gm then there is not a lot you can put on it both weight wise and size wise.
    The TwinStar II has a flying weight of roughly 1500gm and is available for about 85USD in kit form.
    I don't yet have enough programming experience to comment on the UAV side of things but my own experience from the FPV side of things is that many people skimp on the power source and RC side of things with all thier money spent on FPV kit.

    I had an earlier art-tech plane in this style and it was really bad (bad radio, bad flying). This one at least seems to have upgraded the radio.
