Im sure thats a bit slow you know Im sure they have to go faster than that to get the wings to lift
more than 10,000 rotations per minute christ that things gonna take off,
Id say try and hook up a speed controller on it, get it going between 60-120 rpm
a quick caculation, but at 10,000 rpm, it would be turning 166 times per second
it dont need to be fast, to make wings flap, stuff called air does that

having a watch of my clip, its rotating around 50 per minute
i think 60 is going to be my limit with these motors i have in mind
