O.S. Engine OSMG1447 46LA-S Control-Line Powerplant  [OSMG1447]

Power and Precision from the O.S. Engine OSMG1447 46LA-S

Control-line flyers will appreciate the balance of reliability and tuning found in the O.S. Engine OSMG1447 46LA-S. Built to match the expectations of serious pilots, this unit brings O.S. engineering into a control-line package that prioritizes consistent running and straightforward setup.

Steady Throttle with Venturi Intake

The O.S. Engine 46LA-S uses a venturi system in place of a conventional carburetor to keep rpm stable during flight. That steady throttle response is vital for accurate manoeuvres, while the rear-mounted needle valve helps protect the needle assembly on impact and simplifies adjustments trackside.

Rugged Construction and Better Heat Dissipation

Durability is built into the 46LA-S with a nylon backplate mount and ratchet spring that resist vibration-driven changes. The one-piece crankcase is reinforced by heavy-duty webbing, and the squared heat sink head with expanded fin area boosts cooling to help sustain performance during frequent flying sessions.

With its careful design and robust components, the O.S. Engine 46LA-S is a good choice for pilots who want repeatable performance and low-maintenance running in control-line use.
