    I’m trying to get a maple seed to fly using a rubber-power catapult.

    You know the seed that you throw them up and they autorotate down?

    Here is what I’ve done so far:

    You can see a couple of my prototypes.

    Also you can see the apparatus I used to measure the center of gravity of a maple seed.


    Hey Darcy, Ii cannot recall where I saw it, but there is a model that you can buy to build that is essentially a maple copter.
    I was surfing the web one day and came across some model site and there it was the Maple Copter or whatever they call it. essentially a spar with a squarish wing on one end, with some weight on the other end.
    Very similar to what you are doing.


    Thanks for the note.

    If you come cross it again, please let me know as I can’t find anything.

    The concept was called a “charybdis” and it was publish in 1957 in Aeromodeler magazine.
    I built one in high school and it actually flew.
    I saw the recent video a day or two ago, so it’s out there.



    Thanks for that as well. I googled the word charybdis and haven’t found anything except the charybdis sea monster called that.



    I am aware of the Charbydis, there was one called the Chip Chopper a number of years ago in Model Flyer, wild machines, I think there is probabl avid on youtube.
    But this was just a stick and tissue job, sort of like what Darcy shows, but the ‘sail’ was just a rectangle 1/16 frame covered in tissue,looked to be about 2″-3″ appx,then a spar running off the long edge(LE or TE?) of the rectangle, with a blob of plastercine on it for balance. Ive been looking for it, man wish I would have bookmarked it.
