(This is part of a multi-part series on building a FPV mini 240mm quadcopter)

Now that the FPV mini quadcopter frame has been selected we need some motors to make it fly.   For that, I’ve selected 4 SunnySky X2204S 2300kv motors ($23ea).   It was between these or the Tiger’s MN1806 2300kv, but paying $43 each for the Tigers would take this copter out of budget (which is going overboard already) — plus, I like the look of the SunnySky’s.


A little side note, when building a quadcopter there is little instant gratification as you will typically have to wait weeks, if not months, to get all the parts from the different suppliers you will need to order from.
