    I suggested this link over a week ago.
    This is about the 5th one that shows up many days later.
    I`m just wondering which mod I pissed off.

    Having said that... its still a pretty cool effect.

    If you click the `link` button to the right of the editor window, you can actually make a working link for someone to click. Just a friendly tip for ya. Otherwise, newbies might not understand what to do with an un-clickable link.

    Those boomerang things are bound to hit someone on the ground, how do they even get away with this?

    Another engine of this type is suspended under the plane, upside-down to the one you can see. This therefore absorbs the boomerangs and converts them into energy which is fed back to the engine you can see converting energy to boomerangs.

    Propulsion occurs as a result of the loss of potential energy as the newly created boomerangs fall, so the power of the engine is varied very simply by raising or lowering the lower engine.

    As an added safety measure, the boomerangs are made to degrade very rapidly. If they fall more than about 150 metres, they will have dispersed into dust.

    Rather an elegant and efficient system, really, and very safe. There are no reported cases of any of the boomerangs ever reaching the surface, let alone hitting anyone.

    Absolutely true, every word of it!

    [quote">its cool, but i would have imagined that it would be blurry.[/quote">

    That would depend on the exposure time, which is a different thing.

    What you`re getting from this camera is this:

    Picture taken in a very small amount of time.
    Delay before the next picture.
    Picture taken in a very small amount of time.
    Delay before the next picture.

    Repeat.

    So in the very small amount of time during which the picture is taken (very small exposure time), the propeller hardly moves any distance. The picture therefore shows an unblurred propeller.

    By the time the next picture is taken, the propeller has moved a bit.

    So you get a sequence of unblurred shots with gaps in between.

    If you vary the rate at which pictures are taken so that it exactly matches (rpm of the propeller/number of blades) you will get a video of the plane flying with stationary propellers.

    Hmm...as the blades are identical, it isn`t necessary to match rpm/number of blades. A multiple of that will do.

    e.g. 1000rpm prop speed with 5 blades will appear stationary at 200fps, 400fps, 600fps, 800fps, 1000fps, etc.

    WTF are you talking about? They`re BOOMERANGS. They don`t go flying away they JUST COME RIGHT BACK.

    Propeller blade`s rotational frequency is pretty close to a multiple of the camera`s shutter speed.

    so the radius of the propeller is the distance from the centre to the bottom of where you can see stuff moving... i think

    Yeah, this happens because the rate that the propeller blades are passing in front of the camera lens is very close to a multiple of the recording frame rate of the phone. I`ve heard this called the "wagonwheel effect", because you can see a similar thing with wagon wheels in movies, for example.

    It`s rolling shutter effect + wagonwheel effect (rolling shutter making the propellers look so bizarre, and the wagon wheel effect giving the illusion of frame to frame coherence so it looks like the little propeller boomerangs are moving slowly downwards). Really, really cool.

    remember, modern cameras can only record are around 25fps, so if the propellor if rotating at higher than 25 revs per sec, this video is only showing part of the rotating action, thus this effect :)

    I believe it`s to do with how terrible phone cameras are - they record a part of the image at a time and work downwards, therefore for each frame they record different parts of the image at slightly different times. This just happens to be the effect a rotating blade forms.
