Kyosho – RB5T Electric Race Truck

Kyosho has been testing prototypes of their new RB5T electric racing truck and the production truck will make its debut at the Cactus Classic next month. Here are detailed studio photos of the prototype, but technical info is scarce at this time. Here’s what we do no about the truck.

The chassis is an extended version of the RB5 buggy, which will push the truck out to the maximum allowable ROAR legal wheelbase. As you can see the chassis is heavily braced to increase rigidity and the sides are leaned upward to increase ground clearance while cornering.

Like the RB5, the front suspension assembly and business end of the truck are separate structures to make facilitate maintenance. Check out the front body post mount. It’s graphite, but the production units will have molded pieces.

The prototype has a graphite rear shock tower but the production truck will feature molded shock towers. Check out the vertically mounted ball studs for easier roll center adjustment.

The rear suspension arms are obviously prototypes, but the RB5T’s 3-gear transmission with an adjustable ball diff and dual disk slipper clutch will probably be identical to the buggy’s gearbox. No word on the internal gear ratios, which may ultimately be the same as the buggy. Longer aluminum-body threaded shocks will be standard.

The body posts are designed to secure the body closer to the nose section for greater support. Like the buggy, the steering bellcrank will be on the same plane as the steering knuckles to eliminate bump-steer.

The front and rear suspension arms will be longer to increase the truck’s width. The truck will probably feature the same C-hubs, steering knuckles and rear hub carriers for parts compatibility between vehicles.

Here’s another view of the front suspension…
