Welcome to our RC engine tuning company, a subsidiary of Hasi Modellbau, a company founded in 2010 by Silvio and Andrea Hächler. Initially established to provide on-road racing support, we have since expanded our product range and brands.

At our RC engine tuning company, we take pride in offering our customers expert technical knowledge and a wide range of products to meet their needs. We are excited to continue serving you in the future with our high level of expertise and excellent selection of products.

Hasi Tuned was born from the need of Silvio Hachler to have the equipment to be able to compete in the best national and international competitions.

In 2018, he decided to collaborate with Matteo and Cristiano Sartor for the tuning of his engines. Matteo and Cristiano Sartor have been interested in the world of RC micromotors and have gained experience and knowledge by collaborating with all the Italian engine manufacturers.
Since then, the team has always grown and developed to achieve ever more ambitious results. The equipment has become more and more sophisticated and the study to improve more and more careful and scrupulous.
Over the years we began to diversify our product, always focusing on the highest quality and performance, without compromise.
Our product range has expanded with material designed, tested and built by us, conscious of not simply wanting to have our own brand on something built by others.
Our efforts have been rewarded by the satisfaction of our customers around the world and especially by the arrival of former World Champion, Simon Kurzbuch, who chose the Hasi Tuned team to chase his own successes.

In accordance with our development policy in the 2022 season, we have worked on an ambitious project. Many months and a lot of hard work, a lot of technology and innovation together with highly qualified staff inspired by our passion have led in the first weeks of 2023 to a new chapter in our history: A cylinder and piston of our own will be the beating heart of our racing engines.

In this new adventure, we have made a cut with supply material, choosing to follow a different way, our own and that of all customers who want a unique product, carefully and personally assembled in every detail.
Each of our engines is in fact assembled manually, every detail is precisely cured. This is proven by the fact that each piston is lapped in its own cylinder for perfect performance.
Each cylinder is worked to fit perfectly in the crankcase, with no negative clearance.
All surfaces are checked with instruments to measure roughness for maximum smoothness and durability.
Machining is done with Swiss quality machine tools, ever a world reference in precision micromechanics and synonymous of quality.

At our RC engine tuning company, we understand the importance of having a reliable and high-performing engine, and we're committed to helping you achieve your goals. So if you're looking to take your RC vehicle to the next level, don't hesitate to contact us today!
