Schumacher Atom 3 S2 K207

This is 1 of 2 legal spec chassis for the HRC Spec GT12 class.

Experience close, exciting, and fun racing with the awesome new ATOM 3 GT12. GT12 is the perfect racing class for small indoor carpet tracks, and the ATOM 3 is the class leader. It is developed from the British and European championship winning ATOM 2 and includes many new features to make the car easier to drive, easier to maintain, and even faster.

• ‘S2’ Version (#K207) All of the fibre components included are made from our own ‘S2’ Material, including the chassis itself.

• NEW - S2 chassis included in the kit, with increased flexibility, lower centre of gravity and lower cost than the ‘CF’ chassis.
• NEW - Gear Differential offering improved cornering ability in the majority of conditions. On power steering is improved as well as corner entry stability. The car will also drive much flatter and have more predictability in high traction conditions. The ball differential can still be used and is likely to be an improvement only in very low traction conditions. For ultra high grip tracks a spool option is also available.  
• NEW - Top Decks include multiple flexibility settings to further fine tune the flex to gain even more performance.
• NEW - Fully updated front end design with much easier build, far simpler castor adjustment, improved drivability and overall performance.  Maintenance is also reduced.
