3Racing Cero Ultra 2.0

3Racing has released a new version of their competition level 1:10 Electric Touring car platform, the Cero Ultra 2.0 which they are recommending for asphalt use.  In the second generation of Cero Ultra, the main improvement is to use a shorter and narrower chassis to improve cornering efficiency. The belt length is now a shorter S3M345 x 2 to achieve a shorter chassis and more direct acceleration output. The front and rear lower wishbones have been carefully improved to more room for the anti-roll bar movement and a shorter wheelbase. The lay-down front and rear absorbers mounting make the body roll more efficient, the main chassis has a new weight distribution position and a shorty battery socket, and the diameter of the lower wishbones rolling shims has been increased to improve the durability of the chassis plate, a caster has been added to the rear upright to increase the speed of all corners, and the steering system has changed to M4 X 7 bearings To improve accuracy, the upper deck was shortened to accommodate the twist of the chassis.
