Serpent Project 4X blade-less spool outdrives

Serpent have introduced blade-less spool outdrives for the Project 4X touring car. The parts are machined from super-strong spring steel and their design does away with the usual C-shaped driveshafts blades that can break when using high-power motors or when running on very high-grip surfaces. The outdrive cups are strategically machined for a low weight, they offer reduced play for improved efficiency and consistent cornering and they are also usable on the Eryx 411 line of cars.
