Whatever buggy you decide on, i would bring two of them completely ready to race, (motor/pipe/electronics) and enough spares to build a third. Also bring a good pitman to wrench on one while your driving the other. Make your rx pack easy to swap, and bring 2-3 spares of everything including motors/clutch, pipes, servos, recievers, rx packs tx packs, lots of fuel and tires, glowplugs, some adult diapers,lol......ect. It would be fun to do a 24hr race, but the cost and stress would be insane.
