Instruction manual

This is a high performance engine expressly
designed for 50 size helicopters. Since engine
mounting and muffler mounting bolt patterns
are the same as the 50SX-H Hyper, it can be
installed in the existing 50 size helicopters.
Newly designed 40L carburetor enables to
adjust idling, hovering and high speed
independently. Close to 60 size power offers
wide power range suitable for sport flight as
well as 3D flight.

Note on engine installation
The engine mounting bolt hole
size of the 55HZ Hyper is 3.7mm
the same as that for the 50SXH
Hyper. Use 3mm Allen type
screws for securing the engine to
the engine mounts.
