Professional 4WD RC Smart Car Chassis All-metal Motor Rear-Wheel Drive Kit

Elecrow 4WD RC Smart Car Chassis with S3003 Metal Servo Bearing Kit for Arduino Robot Platform DIY Kit Robot Description DescriptionThis is a newly designed 4-wheel car chassis, and ordinary 4-wheel drive is different from this car with rear-wheel drive plus front steering mechanism to achieve the car forward, backward and turn left and right. And professional remote control racing principle, the use of two rod through the steering servo to control the direction of the car. In addition, the steering mechanism of the rear wheel has also been changed. The aluminum fixing piece is integrally formed with the motor and the motor is tightly engaged with the drive shaft. The motor adopts the all-metal gear motor. If you pursue high speed, As long as the 25mm shaft diameter motor can be. The rear wheel incorporates two flange cup bearings to ensure a more flexible motor rotation. Because of the use of more precious metal parts (bearings, transmission gear, connecting rod, metal motor, steering cup, multi-function bracket, etc.), which is expensive, the user can compare the merits, of course, the market is also cheaper Similar to the chassis, work is not on a level of the. We only have fixed mounting holes for arduino platform, if you are other platforms, you need to punch holes or try to install.FeaturesAll-metal motor rear-wheel driveUsing steering gear control car steeringSteering structure with bearings, transmission lossSpecificationsRPM: 17000load current: 1AStart current: 3.5AReduction ratio: 3434:1Car size: 248mm(l) x 146mm(w) x 70mm(h)Weight: 680gPackage listBlack steering wheel x 2Transmission link x2Hexagon adapter x 2M4 locknut x 2Latches M2 * 10 x 2Bearing(12mm) x 2Bearing (8mm)x 2Cross sleeve x1S3003 servo x 1Servo Kit x 1M2.5 * 8 screws x8M3 * 22 Double pass copper column x4M3 * 5 Flat head screw x2Flange bearing disabilities x217MM coupling D-5MM x2Gear x2Rear wheel link x125MM metal gear motor x1Motor mounting bracket x1M3 * 12 Double pass copper column x4M3 * 18 Double pass copper column x4M3 * 35 single-pass copper column x4M3 * 6 nylon screw + M3 nut + nylon column x5Switch x1Tie x10Motor connection cable x3Acrylic Chassis x 1Anti-collision cotton x1M3 * 8 screws x30M3 * 10 screws x16Nut M3 x2065MM wheels x4
