Sorry that is is so short, it's regarding the FPV entry and it looks like I'm nearly out of time! I made a race track, 4 cars, 4 steering wheels and pedals, synchronised races, custom OSD for stats and hold racing events, it's now a small business and I also hold charity races for local charities.
My Facebook page is @formulaFPVracing. I did it using custom electronics, arduino and a Lot of Labview over 2 years, with a 3rd year of tinkering.
