I recently bought a drone(quadcopter).I like how the drone works but now I want to improve my experience and convenience by creating an application that will allow me to control the drone remotely from my PC or Phone.

Some of my initial thoughts were

1.Get a RF detector and detect what signals are being sent to the drone and replicate it using a new transmitter.

2. Replace the control circuit in the drone with an arduino and send corresponding signals to it to fly the drone

Both these methods seem to be kind of farfetched and hard. Is there any way by which my aim can be achieved??

Detailed answers are welcome!!!

How does a computer or phone interface to an aerial vehicle?
