Multirotor used as a signal relay? Answered

So in my years since first asking a question about electronics on here i have learned a whole lot. So much so that i am working on plans to build my own multirotor, rc car, and control system all from scrap and open source parts.

Everything will be arduino controlled for simplicity (i think it will be easier this way) and i would like to use the OrangeRx radio modules.\

So my question is this; if i wanted to put an fpv system on my car and drive it long distances through a neighborhood, how difficult would it be to have a drone follow the car and act as a relay beacon for my transmitter. I know i could easily get the drone to follow the car by using gps but I have no ideas on how to make it a relay, or if thats even economically feasible on a hobby scale.

May I humbly suggest a safer (and possibly cheaper) alternative? I think you should make something similar to an HD downlink that you can mount on your house and use as you relay for your RC excursions. Unfortunately there aren't any instructables on how to make one of these yet andpurchasing one is expensive ($1,500)

how long do you think your drone will stay airborn?

Forget it is my best answer.
Commercial drones use a simple image recognition algorithm to keep a camera fix on a moving object.
This is next to impossible with the limits of an Arduino unless you are a programming pro here.
You could still try externally on a laptop though.
Meaning you process the cam image on the laptop so the program can correct the position of the object to be followed in real time.
For example you paint the car bright orange and your program makes the directional corrections and sends them to the drone so the object always is right in the center of the recorded image.
If you are good with Linux/Android you can also create an app for your tablet to do this.
But how do you include a failsafe? ;)
