Blue is better
The 50SX-H combines balance with usability in any 50 class helicopter. This popular engine is now offered with even more power. The cooling efficiency has been improved using a new blue anodized heat sink head. The new head design offers greatly improved combustion efficiency which delivers stable power for hovering and aerobatic flight. The specially designed carburettor has a large, 10mm diameter intake which gives the engine even more stability. The "MAX-50SX-H RING Hyper" brings even higher performance to the many modellers flying in this class. Another example of O.S.'s untiring quest for excellence.

In helicopter flight, the most desirable characteristics are stability when hovering and power in flight. There are various methods for achieving that performance, but with the Max-50SX-H RING Hyper, we did it using the shape of the combustion chamber and the big bore carburettor. This powerful engine remains stable over its entire RPM range and is bound to give would-be pilots the motivation to take up new challenges.

The machined, aesthetically pleasing, blue anodized heat sink head offers excellent combustion efficiency together with unbeatable cooling performance.
