Genius GTC8.23 Nitro 1:8 GT Chassis
Best known for its 1:5 racing chassis, Italian company Genius Racing has released CAD images of its upcoming 1:8 GT Competition chassis the GTC8.23 Nitro. The new kit is the evolution of its predecessor the Genius GTC8 and features a host of redesigned elements. The new central transmission improves the balance of weights, giving better distribution with respect to the geometric centre of the car. This improvement makes the car more stable in corners. A new rear hub with a pivot ball system makes it easier to adjust toe and consequently track width. This important evolution allows to continuously adjust the toe without changing the pitch of the car. They have also added a new Ackermann position which helps in low grip situations. New large central brake with hexagonal drag improves the self-centring of the brake disc providing more effective and constant braking compared to the previous version. The completely redesigned radio plate allows easier installation and better ergonomics. Its new lowered configuration is designed to simplify all brake, accelerator and steering anchorages. The new large receiver box is positioned in the centre of the servos to optimise the passage of cables and connections.
The design of the new chassis is based on flex and torsion. The chassis is symmetrical in terms of lighting, creating an important cooling effect due to the passage of air. Genius have introduced a new quick release system of the front and rear differentials, this self-centring system facilitates the adjustment of the bevel gear and allows you to raise and lower the differential by 3 mm. With this innovation greatly facilitates disassembly, reassembly and calibration operations , improving the smoothness of the bevel gear.
The battery housing position is independent of the radio plate and any other mechanical part of the model car. In this position the battery does not affect the torsion and flex of the chassis and the low position of the battery helps the weight centre of the model car. One of the design goals of the GTC8.23 was to make the whole chassis have an extremely low centre of gravity , to make the car even easier to drive.
The new rear shock tower features lowered housings for the shock absorbers and body support. The front/rear stiffening system of the GTC8.23 has been completely revised and redesigned. The new stiffening system allows the model to twist but not flex as the spacers are perfectly adjustable and centralised. The new front shock tower features lowered housings for the shock absorbers and body support. The front hub track width is adjustable via pivot ball with possibility of King Ping angle adjustment.
Genius claim they have introduce an absolute novelty in the 1:8 GT segment with its central ball drive system called BDS (Ball Drive Shaft). This ball system increases the smoothness of the whole transmission. This technique already tested by their team in the 1:5 category and proved to be the best solution in terms of performance and durability. The new square adj. roll centre bushings are much more intuitive and simple and have two positions: one central and one offset by 1.5 mm. This makes it possible to adjust the height arms in three positions (low, central, high).
