Hi I'm looking for a gismo that can be connected to speed controllers that drive fan motors. the idea is balance
imagine a horizontal board that can pivot in the centre, with 4 fans fitted front back left and right, if the board is pushed down at the front the front fan will run to raise the front, and the rear fan would run to push down the rear until the horizontal plane is maintained then the fans stop.
I'm thinking the multi rotor units must have something like this on board, any ideas?
