Download and try and FPV simulator from Drone Simulation UK and see if you can climb the leader board during a trial period.
The track is the one used last year north of London. A video from the real event and the simulation below.
Not only great fun, FPV racing is pushing technology. Better smaller batteries, motors and speed controllers. All of which will be seen in light weight commercial RPA.
Tracks have a set number of laps allocated, your event time automatically starts when you leave the grid and completes when you pass the finish line at the end of the allocated number of laps. Your fastest time will automatically be uploaded to the event leaderboard. Your event will be active for the period indicated, during this period you may return to the track at any time and try to improve your leaderboard position.
