Remarks – Dominic Greiner is running a pre-production example of the brand new 200mm car by Serpent, the 748 Natrix, here in Aigen. The car is almost final spec with only some minor tweaks needing to be made before production begins. The car’s designer Michael Salven ran us through the main new features that distinguish this car from its predecessor. The car is lighter, with special attention paid to the weight of the two differential, while the engine has been moved towards the rear end for better weight distribution and can now be removed from the chassis together with its mounts. The radio tray is also new and provides a lower CG and a better weight distribution, the tank being longer and more narrow to bring the servos towards the center of the car. We’ve been told the new shape of the fuel tank also positively affects the engine’s performance. On the rear, the anti-roll bar is now linked further outwards on the suspension arms and is more effective even when using a thinner wire, with its mount also working as as a brake disc guide. At the front a brand new steering block with interchangeable pivot balls mounts and steering braces allow for more adjustments while with flex being a big concern the car now features different possibilities to adjust the car’s overall stiffness.
