In 2007, 3W International began to research and develop its first heavy fuel engines. Several developments were made and tested until the R&D department decided on the final engine design.

After the first prototypes had been produced, the engines were tested under various severe conditions. At the test facility of 3W-Modellmotoren GmbH, the engines had to run without difficulties in an ambient temperature of 45°C, including restarts. To simulate low temperatures, a 5l tank with JET A-1 was stored at -18°C in a deep freezer overnight. Even given these conditions the engines were started without any problems.

The combination of these modifications and the new development constituted the breakthrough in heavy fuel technology. The engines proved their outstanding reliability during the extensive test runs, securing performance beyond limits.
