HPI RACING Venture Scale Builder Kit

Scale Chassis Design and Layout

The Venture rock crawler features a formed steel C-channel chassis with sturdy plastic cross braces as the foundation for a realistic scale truck chassis. To make sure the truck has a front weight bias that improves its climbing ability, the motor and transmission are mounted right up front - just like in a real truck! For additional weight up front, the steering servo is also mounted to the chassis next to the motor. 

Includes HPI Option Parts

The Venture scale crawler truck is packed with features already (you can read all about them below), and the SBK version includes a selection of hand-picked options that will make it even more capable not just on the trail, but also through the most difficult terrain. If you already have a Venture, all of these options are also available separately to enhance and strengthen your truck.

The chassis layout of the Venture, with the forward-mounted motor and transmission, plus the chassis-mounted servo (CMS), puts most of the weight at the front end, giving the Venture ultra-realistic driving performance and an advantage over most other scale trucks when hitting the trail.

All-Metal Transmission

The Venture is the first scale truck to feature strong metal gears throughout its transmission. With a main gear set taken from the ultra-fast and ultra-strong Savage XS Flux, the Venture drivetrain can handle LiPo power up to 3S, as well as brushless motor power with zero upgrades.

Perfect Off-Road Trail Gearing

With the transmission drive ratio of 1.53:1, the overall drivetrain ratio is 7.6:1 for a good all-around gearing and a final drive ratio of 30.4:1 out of the box. This will get you up or down most trails and get you started climbing difficult inclines. With pinion gears of 15-28 teeth, you can get final drive ratios of 30.4:1 to 16.2:1. You can easily alter the ratio with an optional 56-tooth spur and pinion gears from 19-32 teeth for final drive ratios of 22.4:1 to 13.3:1. 

Center Transfer Case

In addition to the motor and transmission at the front, the Venture features a centrally mounted transfer case with a gear ratio of 1.5:1. Whilst putting the maximum amount of weight to the front of the chassis, the central location of the transfer case allows the drivetrain to sit low and down the centerline of the chassis so the driveshafts are perpendicular to the axles for maximum power transfer to the tires.

The low angle and central position of the driveshafts allows for maximum power transfer, so as much power as possible reaches the tires. The driveshafts are equal length front and rear and feature composite slider-style shafts with metal universal joints at each end, where they meet the transfer case and axle. At the axles, 13-tooth pinions and 43-tooth ring gears (axle ratio of 3.31:1) sit inside the "pumpkin" or center of the axles. Each differential is equipped with metal diff lockers for pure 4WD traction at all times.  

Adjustable Slipper Clutch

An externally adjustable slipper lets you tackle slick rocks and loose surfaces without having to make big changes to the setup of the Venture. Correct adjustment gives you the perfect amount of power and grip by reducing wheelspin - and the easy to reach adjustment nut lets you make quick adjustments on the workbench or out on the trail.
