Introducing the Xpress Xpresso K1 which will be in the form of a “K-Chassis”, the first car released as part of our four-car release this year. You must be wondering what is this new “K-Chassis”? K-Cars or Kei-Car are a type of small car which fits into the lowest automotive tax bracket and we have based this K-Chassis on this branch of automotive car!
The Idea of this car came when the Xpress development team were bashing M-Chassis cars around and suddenly one of their friends brought out a Tamiya WR-02 and an idea came into their minds: “What if we designed a chassis which would be able to accept these bodies? At the start it was just trying to fit these bodies on all sorts of M-Chassis’s but found out it was too much hassle when compared to redesigning a new car! This resulted in the creation of the Xpresso K1!
The Concept seemed like all fun and games at the start, however due to the small body size, designing and building a chassis which would fit everything with no compromises was one of the problems faced by the development team. However, after countless prototypes and brainstorming sessions, the team was able to solve the problem. Everything was tucked neatly making use of every millimeter available on the chassis whilst keeping the use of common electronics used on most 1/10 models (i.e. servo, motor, esc). We recommend running this car with 540 sized 13.5T Blinky for the perfect balance between Speed and Control!
Here is a comparison between the wheelbase of the Xpress Xpresso K1 (Closest), Xpress Mini Road Runner II (MRR2) AWD M-Chassis (In the middle) and the Legendary Road Runner Touring Car (Furthest Away).
The Future we have laid ahead will include a body that we will create to suit this chassis which will act as an extra choice to the bodies already available. As seen in the photos, even with the limited room, there will be a future upgrade of Anti-Rollbars, which will fit snugly inside the suspension system. With a simple Ackermann change on the steering block you will get a high steering angle required for RWD drifting! Speaking of drift, we will release tires with formula specific to RWD drifting.
Simple Steering geometry change for easy transformation to RWD drift car.
