O.S. Engine OS-15638 55HZ Hyper 50-Class Helicopter Engine with Power Boost Pipe  [OS-15638]

Performance summary for the O.S. Engine OS-15638

The O.S. Engine OS-15638 55HZ Hyper brings high-output performance to 50-class helicopters. Built to produce power on par with many 60-size engines, it suits pilots chasing aggressive 3D flight while fitting standard 50-size mounts for a straightforward upgrade path.

Key engineering features of the 55HZ Hyper

Durability and stable running are driven by the new rear bearing design that copes with high RPM loads. The dual needle 40L carburetor combined with a four-arm throttle lever gives precise throttle control and works cleanly with a range of servo setups. These design elements help maintain steady hover and reliable idling during demanding maneuvers.

Power Boost Pipe tuning and benefits

The supplied PowerBoost pipe is matched to the Max-55HZ Hyper to optimise exhaust flow across the rev range. Its polished aluminium shell aids heat dispersion and adds a clean look, while the pipe helps the engine reach the RPMs needed for advanced aerobatics and smooth throttle transitions in hover and idle.

For experienced pilots who want to step up their 3D performance, the O.S. Engine OS-15638 55HZ Hyper delivers robust construction and the tuning range needed for competitive and precision flying.
