Tamiya #70107 Remote Controlled Shovel Dozer Kitset 【 Really Diggin' It 】 Bulldozers are often seen at construction sites and this kit allows you to create a simple working model of one. A 3-channel remote control with self-neutral control sticks operates the forward/reverse, left/right turning, and up/down shovel bucket movements. As the shovel bucket moves, its angle also changes simultaneously thanks to adjuster rods. To prevent damage due to excessive loads, the shovel movement gearbox features a thoughtful clutch mechanism. The easy-to-assemble kit consists of plastic parts which attach onto the wooden chassis and even the road wheels do not require any screws for attachment.
