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.
