RC4WD BULLY II MOA RTR COMPETITION CRAWLER – Z-RTR0027 The RC4WD Bully II MOA RTR is a purpose-built competition crawler designed around a Motor-On-Axle drivetrain, CNC-machined Bully II axles, lightweight carbon-fiber chassis components and independent motor control through RC4WD's Rocker Dig II system. It arrives professionally prebuilt and is engineered for technical rock crawling rather than general trail driving. COMPETITION-FOCUSED FEATURES CNC-machined aluminum Bully II Competition axles MOA — Motor-On-Axle drivetrain Dual-motor architecture for low center of gravity and precise control Steel heavy-duty internal gears Clockable C-hubs 4-link front and rear suspension Aluminum 90 mm internal-spring shocks Titanium links Carbon-fiber and Delrin chassis Carbon-fiber battery plate High-clearance competition chassis design Easy-to-paint Lexan body panels AXLES & GEARING Final drive ratio: 40.7:1 Pinion gear: 0.8 Mod, 14T Hex width: 219.5 mm Hardened-steel gears Billet-aluminum axle cases Full ball bearings XVD front axle shafts WHEELS, TIRES & SUSPENSION 2.2-inch lightweight competition beadlock wheels Carbon-fiber and Delrin wheel construction Hex-type hubs Wheel width: 25.3 mm Backspacing: 15 mm Bully 2.2 Competition Tires in Advanced X2SS compound 90 mm aluminum shocks; can be oil-filled DIMENSIONS Wheelbase: 306 mm / 12 in Width: 254 mm / 10 in Height: 190 mm / 7.5 in Ground clearance: 97 mm / 3.8 in Weight: 1.99 kg / 4.38 lb ELECTRONICS RC4WD Twister Metal Gear Digital Servo Servo torque: 277.6 oz-in @ 6V RC4WD Outcry III waterproof brushed ESC with drag brake Rocker Dig II electronic dig controller for independent front/rear motor control XR4 4-channel 2.4GHz transmitter/receiver 3-position switch for DIG and other channel functions Dual RC4WD Boost rebuildable 35T crawler motors WHAT'S INCLUDED 1x RC4WD Bully II MOA RTR Competition Crawler REQUIRED TO COMPLETE Compatible battery per ESC requirements 2S–3S LiPo supported by RC4WD's recommended setup Suggested compact battery footprint: approximately 57 mm long × 22 mm wide Compatible battery charger KEY REPLACEMENT PARTS Bully II front axle — Z-A0012 Bully II rear axle — Z-A0084 Rocker 2.2 Competition Beadlock Wheels — Z-W0178 Bully 2.2 Competition Tire — Z-T0134 Rocker Dig II — Z-E0028 XR4 4-Channel Radio — Z-R0006 Twister Metal Gear Digital Servo — Z-E0035 35T Boost Rebuildable 540 Motor — Z-E0045 Bully II MOA Titanium Link Set — Z-S1801 SETUP NOTES Inspect all installed hardware before first competition or practice session. Use thread lock sparingly on metal-to-metal fasteners where appropriate. Hand-painted body panels may show minor cosmetic variations. MOA/dig operation requires more driver setup and practice than a conventional single-motor crawler. Battery placement has a major effect on center of gravity and weight bias; keep the pack compact and securely mounted. GASHEAD RC COMPETITION NOTE The Bully II is not designed around trail realism — it is designed around line choice, breakover, independent axle control and low center of gravity. The Rocker Dig II and dual-motor MOA drivetrain are central to how this platform performs. Spend time learning front/rear dig behavior, axle loading and tire placement before changing parts; the stock architecture is already highly specialized. SKU: Z-RTR0027
