Product description

Battery & charger choices

Battery and charger sold separately. This factory brushed setup uses an IC3/EC3 connection and a 2S LiPo maximum.

Choose one charger: S155 G2 55W AC — budget choice or S2100 G2 dual 100W AC — charge two packs at once.

Direct-connect battery: 5000mAh 2S Smart G2, IC3 (subject to availability).

IC5 battery alternative: 5000mAh 2S 100C Smart G2, IC5 or the 2S IC5 PowerStage battery + S155 bundle. Both IC5 options require the SPMXCA507 adapter to connect to this IC3-equipped car. A PowerStage bundle already includes its charger.

Setup note: When changing from NiMH to LiPo, select the ESC’s LiPo low-voltage cutoff mode as described in the vehicle manual. Do not use 3S in the factory brushed setup.

About the Granite Mega 665


Clipless Body

The realistically styled Granite Mega 665 4x4 monster truck body is held securely in place by a hidden clipless body retention system. This ensures your body stays in place, looking great during any bash session.

Chassis & Suspension

The durable chassis is ventilated to keep onboard components cool. Larger side guards provide maximum protection from dirt and debris. Adjustable suspension and oil-filled coil over shocks soak up bumps. With a 3S brushless-ready transmission included as standard, the Arrma Granite 665 4x4 is equipped for an easy upgrade to brushless power for greater efficiency and higher power whenever you’re ready.

Electronics

Faster, more powerful, and 11% larger than the 550-size motor of its predecessor, the GRANITE MEGA 665 4x4 monster truck’s 14-turn MEGA 665 High Torque Brushed Motor includes an aluminum motor heatsink and 35mm motor cooling fan to boost efficiency and performance. The included Spektrum S661 Metal Gear servo and SLT2 Transmitter are perfect for off-road 2S bashing. The only things needed to get out and drive are a 2S LiPo and a compatible LiPo balance charger.
