The CR3.4 SHERPA PRO was the best we could offer! The outstanding features offered by the CR3.4 chassis are now complemented by the popular programmable Quicrun 1080 WP speed controller from Hobbywing. In cooperation with a 755er brushed motor, the controller really gets the absolute maximum out of the vehicle.Chassis & suspension:A realistically designed 5 mm CNC-milled aluminum frame with a heavy-duty aluminum 4-handlebar suspension system and steel cardan shafts. Oil-filled aluminum shock absorbers with 3mm piston rods ensure a silky-soft and realistic response (tuning springs available in soft and hard separately).Portal axes:Portal axles not only offer a greater distance from the differential housing to the ground than conventional axles, they also have another positive feature. In conventional crawlers, the torque applied so much force that the vehicle jumps over the obstacle. The design of the portal axles reduces the gear ratio at the wheels and virtually eliminates the torque surges of the drive. The overall reduction ratio of the final drive is more than twice as high as for non-portable versions to ensure smooth running.Steering:A unique hydraulic steering shock absorber design combined with a 25kg (actuating power) digital and waterproof steering servo, drive shafts made of hardened steel and a steering angle of 45.8° offer the best options for any terrain.Drive system:The CR3.4 SHERPA PRO has a 2-speed steel transmission, with which you can overcome difficult terrain and quickly get to the next obstacle. Simply press a button on the remote control and change from transmission ratio 1/37.1 (low speed) to 1/15.1 (high speed). Lock and unlock the front and rear differential independantly of each other to achieve the maximum power on the track - all remotely controlled with your remote control and 2 built-in mini-servos. Leave the differential unlocked to allow smooth handling at high speed. On technically challenging grounds, you can lock the front differential, the rear differential, or even both to handle extreme terrain. An aluminum motor bracket and adjustable slip clutch provide additional protection under extreme conditions. Hardened differential gear and drive parts made of steel - designed for high loads.Electronics:The drive concept - powered by Hobbywing - includes the universally popular QuicRun1080 WP speed controller and a 755er motor for rich torque. The built-in BEC is adjustable in voltage, 6V or 7.4 V and with 6A peak load also sufficiently dimensioned for strong servos. With the accompanying LED programming card, a simple setting is done quickly while traveling. With the adjustable parameters, there are over 80 setting options, one soon found the optimal setup for the vehicle. A 25kg digital steering servo with metal gears and 3x 17g mini servos with 0.9kg adjusting force for transmission ratio and differential lock/unlocking are already installed. All servos are waterproof. The 6-channel radio system with 2.4 GHz gives you total control over your vehicle - whether light unit, 2-speed transmission, differential locks or setting the maximum speed.Lighting system:All Sherpas are equipped with a separately switchable light unit. This consists of bad-looking headlights, tail lights, turn signals (when steering is moving), searchlight (on the bonnet), position lights, hazard lights (front and rear), brake light and a light strip on the roof. The light unit is installed in the 6-channel receiver of the vehicle. You want to use another 6-channel remote control without losing the lighting functions? No problem! For a description of how to proceed, refer to the manual.Scale Details:Stylish 1.9-inch beadlock wheels with aluminum rings and 10-pin design. Super-soft tires with realistic side wall flex for maximum traction on any rock. Wheel size: 43x120 mm. Rocksliders and molded inner fenders protect the chassis from dirt and damage. Flip-Top body with magnetic holder, locking screw and easy to open battery compartment. 1.2mm PC body including cockpit, driver figure and many attachment parts such as towing hook (front and rear), rear view mirror, snorkel, door mounting set, 2 petrol tank dummies, Jack, roof carrier, tank filler neck, door handles, hood holder and number plates.This text is machine translated.
