Thank you for viewing. This is an FRP front teeter-totter. By attaching the teeter-totter to an AT front bumper and then attaching a polycarbonate body, etc., you'll have a complete "paka-paka" (flapping) setup. The front mounting holes have been reinforced with eyelets. They are angled for smooth opening and closing. Since it's Tamiya genuine, you can use it with confidence in official races. 【Parts Used】 - Product Name: Super X Chassis FRP Rear Roller Stay Part Number: 15243 - Product Name: FRP Multi-Wide Rear Stay Part Number: 15430 It should be possible to install on various chassis.
