EX 230

The EX230 is a high-power engine specifically developed for RC aircraft and UAV applications.

It is the result of over two years of intensive R&D, validation, and long-duration testing, with a strong focus on thermal stability, reliability, and real-world operating conditions.

One of the key strengths of the EX230 is its excellent temperature control performance, even during sustained high-load operation. 

Thermal management has been a core design objective from the beginning, ensuring stable output and long-term durability for both RC and professional UAV platforms.

With a total weight of 5,917 grams, the EX230 offers an optimized balance between horsepower and structural efficiency.

Its excellent thermal management, combined with low vibration levels and smooth operation, delivers reliable performance across demanding operating conditions.

The dedicated mechanical architecture ensures stable and predictable operation, even under extreme loads and environments.

*** The EX230 is equipped with a specially reinforced CDI configured with Specialised ignition timing. This CDI is exclusively designed for the EX230 and must not be used in conjunction with any other twin-cylinder engines. Using this CDI with a different engine platform may result in incorrect ignition timing, which can lead to severe engine damage, loss of control, and potential personal injury. Please observe this restriction strictly and ensure that the EX230 CDI is used only with the EX230 engine. Any misuse or cross-application is strictly prohibited. ***
