The cars that I disassembled for this project were both Himoto HI4185/HI4185BL. Only parts that I used from them are front and rear differentials (The whole shock tower assembly with wheels, gearbox and steering links). I replaced each original bumper with shorter 3D printed version.
Parts List:
2x Himoto Front Differential
2x Himoto Rear Differential
2x 5mm Red LED
2x 12V 5050 RGB LED Strip with DIP Switch for Drones (47x10mm)
