Adding a 5th motor to Hubsan x4
I am trying to add a 5th servo motor to my Hubsan x4 quadcopter. I know that there are two extra leads running off of the flight controller, but there are no more buttons on the controller. Is there any way (Bluetooth, external micro-receiver/transmitter, WiFi, Arduino, ect..) that I can independently operate an extra motor?
Is this a good question?
