Serpent have introduced new blade less spool outdrives for the Project 4X. These spool outdrives reduce the risk of breaking driveshaft blades by simply not using them. By using super strong springsteel there is almost no wear on this part.
The parts are strategically machined, to offer a controlled flex characteristic, ensuring some energy consumption in hard crashes without bending or breaking, and at the same time saving some weight. By eliminating the driveshaft blade, the play in the assembly is also reduced, ensuring a consistent turn- in characteristic. The spool outdrives can also be used in the Serpent Eryx line of cars.
