Rubberband powered counter rotating flying machine

thingiverse

while this is only a simplistic model, its like i envision these as a more elegant way for thing needing to function at higher altitudes (cell phone towers, for example) rather than an ugly not very well hidden tower a slow flying electrically powered version of this could lift itself into the air and become a more integrated part in the landscape is it moves, constantly unlike the static towers currently existing. Instructions To have this function correctly you will need either a bearing (approximately, doesn't have to be exact) of around 22mm nor more than 24, and a rubber band. the bearing will be used to aid in smooth rotation for the two sides, and the rubber band will simply be attached to either side and when ready to test fly, be twisted. the last parts you'll need are some (as straight as possible) skewers, or you can edit the file on Tinkercad to make it fit to any other sort of wings you can think of.
