Processed for MS flexible chassis. ・The lower unit connection is fixed with adhesive to increase strength. ・There are scratches from processing. There are scratches because it has been test-driven once. ・The internal structure is not disclosed, but it applies GFIX technology. ・You can easily attach and detach the connecting gear unit by simply opening the gear cover of the connecting part. (If you remove the gear unit, it will not drive, so it will be treated as a skid roller, and you may be able to enter Tamiya official races.) ・Reference (Photos 7-8): When full cowl roller stays are attached to the front and rear, the total length is 162-163mm, which complies with the regulations. ・Gears 3.5 and 3.7 can be used. (Only compatible with G22 pink gears) ・Due to the shaft spacing limitations, a tire diameter of 22.2mm or less is recommended. (Minimum ground clearance needs adjustment) ・Reference: Structurally, it can also be attached to the front, allowing you to create a machine like the Tyrrell P34 of yesteryear. (Flexible processing of the center chassis is required) ・Reference (Photo 9): When attached to both the front and rear, you can achieve an amazing 8-wheel drive! (Just like the Todoroki Special T-3, total length: 162mm) ■Other Parts ・Lightweight center chassis: New processing, never run.
