Simple installation, stronger, with install guide;
– Support double layer chassis.
– Increasing mounting holes for 5-AA battery and 2-lithium battery.
– Has two speed disks hole can be used with speed sensor.
– Using strong 130 anti-jamming magnetic torque motors, motor running stability, jitter-free. Voltage 3~10V, transmission 1:48 than fast, speed cars best.
– Thickening to increase chassis, 22cm, two-wheel width 17.5CM, head width 15.6CM, Middle 12cm wide.
Measuring 7.2V idle current is about 130mA, around ground running current of 200mA
