How to find out the height and speed of the RC planes?

    When I first bought my townhouse, I thought the huge park behind was
    good. Three days after I moved in, I realized it was a testing ground of the
    RC plane fans. Tens of noisy planes hover arround the area every weekend.

    Now for a technological exercise, I have decided to design a RCPlaneHunter
    to bring them down or destroy them in the sky.

    First idea:

    A device installed on my kid's 4wheeler, which contains a digcam censor,
    a powerful uP with some field programmable gate array chips, an air rifle
    which can shoot a plastic bullet 200 meters, plus some sensors yet to find
    out. My electronics will detect the speed, direction and height of the
    determine the firing angle and time of my rifle and fire.

    What are the algorithms to calculate the speed, direction and height of the

    Any new ideas are also welcome.

    Just take out the operators, not the devices. Works every time. Also: Just
    as illegal as the other concept you are proposing. Did these flying groups
    "Pre-Exist" your purchase of the townhouse? FWIW??
  3. New idea: Check your local laws. If they are breaking one or more, have
    them brought into compliance. If they aren't, realize you should have
    scouted your purchase out beforehand.

  5. Take up the hobby. I understand it's actually quite fun. Then, what you
    currently perceive as an annoying and uninteresting buzz will be infused
    with the memory of joy you felt during your first 3-point landing, or
    the thrill of learning to fly an outside loop.

    Also, you won't have to worry about retaliatory strikes from RC planes
    dropping paint-gun pellets.

    Second suggestion: noise cancelling headset. $40 at Radio Shack. I've
    heard the bose is superior to the philips.

    Third suggestion: double or triple pane glass. When I bought my house, I
    (sadly) didn't consider the noise that might be generated by the
    neighbor's huge air-conditioning unit outside my bedroom window. That,
    and their obnoxious pool pump, collaborate to generate a deafening drone
    on hot nights (where one would naturally enjoy open windows.). However,
    double pane glass helped with the noise immensely, dropping it to quite
    managable levels. Not only that, but my neighbor with the noisy air
    conditioner saw us do it, and decided to do it himself. Now, his air
    conditioner runs 1/2 as much, due to the superior insulation.

    If they are RC, can't you just disrupt the radio link?

    With white noise or, more elegantly, with opposite phase interference

    That's why RC military airplanes have not become popular yet.

    You'd never be able to hit an RC plane with a klooge like this.

    What you do is, get your own plane, learn to fly it, and mount rockets on

    Test it out on the police chopper just for S&G.

    Good Luck!

    Rich, great idea! Especially that last part! That will for sure tell
    him whether or not his idea is any good. And if it really does work,
    even a little, he'll get to live someplace where it's guaranteed he
    won't be bothered by RC planes.

    Eerily, on CSI last night, the murder weapon was an RC chopper
    with rifles mounted on it, normally used by some special police
    SWAT-type unit.
