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

Launching first O.S. gas engine-designed specifically for R/C!

Its like glance at to many other O.S. 2-cycle machines, with an important quantity of extra-deep and -thin cooling fins on crankcase and mind. A genuine 1-piece crankcase design eliminates gaskets and enhances power and accuracy.

An exceptional front-mounted carbohydrate, but provides some performance advantages.

• Better carburetor cooling, to get more consistent motor runs and high end.
• Requires smaller standoffs, which leads to better installation (mounting) less vibration in general.
• Simple, direct installation of the throttle and choke linkages.

Another major performance benefit is the IG-01 Capacitive Discharge Ignition. Developed from proprietary O.S. technology, it makes use of a microcomputer programmed for optimum spark advance. Magnetic sensors regarding crankcase and prop drive detect ignition timing. The IG-01 additionally detects and compensates for wet plugs, ensuring fast starts. Made to accept numerous input voltages, the IG-01 calls for minimal contained in standby mode and features a low-voltage caution (periodic motor operation).

Features:

• IG-01 Capacitive Discharge Ignition utilizes a microcomputer programmed for optimum spark advance through the use of magnetic sensors about the crankcase and prop drive, the IG-01 also detects and compensates for damp plugs to make sure constant quick starts, also requires minimum contained in stand-by mode and features a lowered voltage care (periodic engine procedure)
• Front mounted carburetor continues to be cooler at a reduced price heat percolation and more constant performance, simple and easy direct throttle and choke linkages
• Unique one-piece crankcase removes gaskets and enhances energy and precision
• Front induction rotary valve crankshaft design for good opening and closing of valve for optimum timing, no oil seal required which removes RPM loss considering extra friction
• Massive front and straight back crankshaft bearings for extended life and optimum energy production
• Slim superior piston band and high-strength aluminum alloy piston for paid down break-in and high compression through the very first run
