Schumacher CAT SX3 1/10th Competition 4WD

The new CAT SX3 follows on from the highly successful CAT SX range. Stronger and more durable than ever before! An all new mid-motor design with central lipo battery positioning offers fantastic balance, control and agility. Jumping like the Pro's is made super easy with the new compact layout and corresponding motor/wheel rotation. Awesome acceleration and straight line speeds are still achieved.

With the inclusion of the excellent large capacity big bore shocks, high down force MAX sized rear wing and new cool body the CAT SX3 remains the market leader.

Designed to race, designed to win! The CAT SX3.
