Specification: Noise: Size: 25 x 14cm (L x W) Wheel size: 6 x 2.7cm (Dia. x H) Motor power supply is 3V ~ 6V. All the parameter above is tested without load. Installation steps: STEP 1: Insert the fastener into hte chassis after tearing off the yellow protection wrap of the chassis,the fastener and the code wheel STEP 2: Install the code wheel and fix the motor to the chassis .(Attention,the copper sheet of the leading wire of the motor should face outward,the same side of the wheel) STEP 3: Fix the motor to the chassis ,then insert and tighten the screws. STEP 4: Insert the screws and fix the battery container. STEP 5: Insert the spacer and tighten the 8 screws to fix the hammer caster.Hold tight and insert the motor(protection fastener) to the wheel . Note: This car is the tachometer encoder. Come with a 4 AA battery box (batteries not included). The car Chassis is transparent, you need to tear out protective paper. Package Included: 2 x Car chassis 4 x Gear motor (1:48) 4 x Car tire 4 x Speed encoder 8 x Fastener 1 x Battery box(batteries not included) All necessary screw and nut. Review: Low quality & Broken - The parts were packed in a plastic bag, the base was broken. Review: Okay, I have waited three weeks to do this review to give the seller the benefit of the doubt. the product looked good at first glance but after assembling I noticed one of the motors was "skipping" rotations. I pulled it apart and found a broken gear in the gear box. I reported it to the seller and they promised to send a replacement... as of this writing I have received nothing from them. over all the product is average. when I purchased I thought the value was good but it turned out I had to order more parts to make it work so, not so great. I give this product a 3 out of 5 overall. UPDATE... Today I received the replacement motor. change rating to 4 out of 5 stars... Seller took care of me and I am happy. ## Features - Intelligent Tracing Robot car chassis, high degree of freedom, ideal for DIY subject, science education, development of hobbies and interest, educational toys for kids. - Mechanical structure is simple, 4 DC gear motors, flexible turning, eco-friendly chassis is stability and very easy to expand. - No add-ins is very convenient, the entire system highly integrated.
