Land Rover Defender 1/10 RC car - HB Toys ZP1001 (ZP1002) - a simplified copy of the Land Rover Defender Traxxas TRX-4 Defender.

shaft diameter 3mm, length 78mm - 1 piece
shaft diameter 3mm, length 58.5mm - 1 piece
shaft diameter 1.6mm, length ~29mm - 2 piece
shaft diameter 1.6mm, length ~10mm (propeller shaft cross) - 4 piece
shaft diameter 1.6mm, length ~4,5mm (propeller shaft cross) - 4 piece
*it's can be made from a nail of the appropriate diameter by cutting it to the desired length.

bearing 3x10x4 - 4 pieces - Link

m4 grub hex screws - 2 pieces
m2.5x8 ****on head self tapping screws - 9 pieces
m2x6 screws (for servo) - 3 pieces
