World-Champion Chassis & Easy Handling

Based on the Kyosho Ultima RB6 that won the 2013 Japan National Electric Off-Road Championship and the 2WD Racing Buggy World Championship, this ready-to-run buggy features the same chassis—plus easy handling and enhanced control. The black anodized Duralumin chassis, equipped with resin side guards, provides superior strength and durability, with rigidity in pitching direction and flexibility for roll direction. At the center of it all is a sensorless brushless motor that delivers plenty of power through the specially designed ESC. This pre-assembled Readyset is raring to go, with all electronics installed. You’ll just need a battery, charger, and batteries to get started.

Note: This drop qualifies for a $75 off coupon! At checkout, you’ll have the option to add a Venom Sport 2S 7.4v 5000mah Lipo Battery (+ $55) and a Hitec X1 AC/DC Multi-Chemistry Charger (+ $50).
