Sagami RC Fab NX ver2 1:12
Japan’s Sagami RC Fab has announced the upcoming release of their SRF-NX ver2 1:12 kit, a design based on the legendary NX101 manufactured by R&D Ishuhara that won the All Japan Championship in 1984. The previous SRF-NX was released in January 2023 as a “bare kit,” requiring users to provide their own dampers and rear axle but now the Ver2 comes as a full complete kit. Currently, it is planned to be sold exclusively online, with approximately 50 units available. The main features of the Ver2, which will be limited to jusy 50 kits, is a 2.5mm thick carbon fibre main chassis and rear cross plate. The previous model’s main chassis was made of 2mm thick black FRP. The rear cross brace, which supports the body posts and roll damper, is also made of the same material. The T-bar is made of 1.5mm thick black FRP, and the most of aluminium parts are made of 7075-T6 material. Also new is the -1 degree Camber Front Crossbar. This was previously released as a very limited-quantity option to improve cornering performance at high speeds. The height of the left and right crossbar mounts has been lowered to ensure sufficient ride height even with small-diameter front tyres. The front body post position has been moved forward and are positioned above the white resin bumper to prevent the front of the body from interfering with the track surface when using modern thin-walled bodies. It can also be changed back to the classic, traditional position.
A Morotech friction-type pitching damper is standard equipment. The spring is an original design, and a soft specification was selected to match the rigidity of the T-bar. The previous model lacked a roll damper, but ver2 is equipped with single roll damper, the same type used in the Team Bomber AK12X. This significantly improves roll control, allowing it to handle a wider range of surfaces. The legendary NX101 used an AYK GX1200 centre differential, and the T-bar was symmetrical. However, in the previous model, to accommodate the ball differential, the rear pod was shifted to the left, forcing an asymmetrical T-bar. In the SRF-NX ver2, a new, thinner ball differential system was adopted, successfully achieving a symmetrical T-bar. The newly developed, slim ball differential comes standard with 6 ceramic differential balls and thrust bearings. The outer bearing is designed not to bear thrust load, ensuring a long lifespan. The rear axle is made of steel and while heavier than carbon fibre axles, its combination with the ball differential primarily aims to ensure traction on low-grip surfaces.
