woah what are you talking abour remote power source?
that is exactly what im trying to do...a small hovercraft...
no fan size in particular, but it just needs to be moving plenty of air to support itself in the air as well as a little more weight.
what i need to do is get 6 or 8 fans in a circle all blowing a different direction....well not different, but they are all blowing a direction...
for example, if i used 8 fans, they would be positioned like a stop sign and all would be blowing away from the center. they, however, would not be blowing forward or backward, but instead north, northeast, east, southeast, south, southwest, west, and northwest.
those 8 fans would keep it suspended in the air and i think all of them would cancel out the others force. this is what im aiming for. get the object to stay in the air wherever i put it. i hold it at eye level, turn it on, and hopefully it will stay at eye level. then i want to put a fan in the center on a servo from a RC car or something and that be the directional fan.
does any of this make sense?
what i need:
6 or 8 small powerful and energy efficient fans
1 center fan, also powerful and efficient
material to mount them in a circle that is strong enough but very light
some kind of power source...i have no idea what to use for power
