FPV drones are usually small hand built drones that are very fast and really responsive. The issue with FPV is that the learning curve is too large for the amount of time people are willing to spend. It can take upwards of 10 hours to build a working drone and even longer to learn how to fly. Despite all of these factors, I was able to set aside enough time over a 2 month period to teach myself how to build and fly an FPV racing drone.
