From our passion for Scalers and 4×4 RC Cars, we created a product line dedicated to the world’s most popular models, Tamiya and Axial.
Our conversion kits can make the Tamiya CC-01 and Axial SCX10 even stronger while also making them more flexible and lighter. In short, suitable for tackling any type of terrain and overcoming any obstacle.
The two chassis for Scalers and Crawlers, Fizzy and Wolf, and the CC01 Longheroni Conversion Kit, are our solutions for model enthusiasts who want to take on new challenges and new adventures, on the track and along the most winding trails, with small but mighty radio-controlled off-road vehicles.
The strength of our products, in addition to their high quality and the possibility of customizing the models, lies in the fact that we test them ourselves, not only to make sure we do not disappoint our customers, but because we are the first users and fans of this cult hobby, and we understand the needs of all Scaler enthusiasts.
We take care of every detail, because we love them too. We also have the opportunity to carry out tests in the forests of Irpinia, among rocky climbs, clay terrain, loose ground in summer, snow in winter and mud pits in spring. Everything that can severely test the durability of the various models.
Fizzy and Wolf: two new chassis for RC Scalers
And that is precisely why the Wolf chassis is named after the animal that is the symbol of Irpinia, the wolf, which roams the still-unspoiled forests and rugged trails that become extreme circuits for unstoppable off-road vehicles.
Wolf’s shock towers, designed for the most extreme trails, are fully adjustable and reversible, while the central skid is secured to two flexible supports that allow the transmission to dynamically adjust the operating angles of the shafts. An inclined, ultra-compact central skid is also available for the toughest climbs. The chassis has a maximum width of 78mm and a minimum width of 65mm.
The Fizzy chassis, designed according to the technical guidance of model enthusiast Manuele Colombo, who tested it at the Crazy Road Model Club circuit in Zelo Buon Persico, in the province of Lodi (a nationally renowned off-road RC modeling facility), is instead designed for competitions. It was created to be lightweight, streamlined and sturdy, with a very low center of gravity. It is perfectly suited to the use of portal axles. The shock towers are fully adjustable and reversible, while the central skid, positioned entirely within the profile of the inclined frame, can be moved forward or backward. The chassis has a maximum width of 68mm and a minimum width of 60mm.
RC4x4 Chassis Made in Italy
Fizzy and Wolf are very lightweight. Their total weight, including screws and plastic components, is 180g in the carbon fiber configuration and 240g in the aluminum configuration. And they are completely made in Italy: even the Allen screws used are made from Italian material and have the highest strength class, namely grade 12.9 bolts.
For both chassis, it is possible to choose aluminum frame rails and shock mounts (anodized, 6082 alloy), or carbon fiber. The frame is 3mm thick. They can also be used with the steering servo mounted horizontally on the axle or on the chassis.
Conversion Kit for Tamiya CC-01
Let us also take a closer look at the conversion kit for the famous Tamiya CC-01 chassis, which makes it possible to transform the model into a modern Scaler with a frame-rail chassis.
A sturdier gearbox, the possibility to extend the wheelbase across 4 positions, install motor pinions from 12T to 29T, and the front-mounted steering servo are just some of the improvements that the 3DRap CC01 Longheroni Conversion Kit can bring to the standard chassis, in addition to making the model lighter and improving front suspension travel and caster.
One component of the kit also makes it possible to bring the rear bevel gears closer together, preventing them from slipping under the most extreme conditions.
The kit, which improves the vehicle’s dynamics and allows countless modifications and larger tires to be fitted, is completely plug and play and includes:
- aluminum chassis;
- aluminum motor mount;
- gearbox with rubber gasket;
- central tub and rear axle link mount;
- body mounts;
- front suspension mounts;
- steering servo mounts;
- rear bevel gear modification;
- battery holder and hardware.
Everything you need to make the Tamiya CC-01 even more powerful.
Once again, the variety of our local area, Irpinia, allows us to develop products that can compete worldwide, in this case bringing innovation to the most dynamic side of RC modeling as well.
If you are a Scaler enthusiast, you simply have to try the 3DRap products dedicated to them, making your small but mighty off-road vehicle even more efficient and highly customized.
