O.S. Engine #38000 - OS GT55  [OS-38000]

Launching 1st O.S. gasoline engine-designed especially for R/C!

Its similar to look at to many other O.S. 2-cycle engines, with a significant number of extra-deep and -thin cooling fins on crankcase and mind. An original 1-piece crankcase design removes gaskets and enhances energy and precision.

A distinctive front-mounted carb, but provides a few performance advantages.

• Better carburetor cooling, for more consistent engine runs and high performance.
• Requires smaller standoffs, which results in more secure installation (mounting) much less vibration in general.
• Simple, direct installation of the throttle and choke linkages.

Another major performance advantage is the IG-01 Capacitive Discharge Ignition. Developed from proprietary O.S. technology, it uses a microcomputer programmed for maximum spark advance. Magnetic sensors regarding crankcase and prop drive detect ignition timing. The IG-01 also detects and compensates for wet plugs, ensuring quick begins. Designed to accept many input voltages, the IG-01 requires minimal present in standby mode and features a low-voltage warning (intermittent motor operation).

Features:

• IG-01 Capacitive Discharge Ignition utilizes a microcomputer programmed for optimum spark advance by using magnetic sensors regarding the crankcase and prop drive, the IG-01 also detects and compensates for damp plugs to make certain consistent quick starts, additionally requires minimum present in stand-by mode and features a reduced voltage caution (intermittent motor procedure)
• Front mounted carburetor remains cooler at a lower price temperature percolation and more consistent performance, simple and easy direct throttle and choke linkages
• Unique one-piece crankcase removes gaskets and enhances power and precision
• Front induction rotary valve crankshaft design for good opening and closing of valve for maximum timing, no oil seal needed which eliminates RPM loss due to extra friction
• Massive front and back crankshaft bearings for longer life and optimum power production
• Slim superior piston band and high-strength aluminum alloy piston for reduced break-in and high compression from the very first run
