GT55 Gas Engine | | FS-200S-P SPECIFICATIONS:
- Displacement: 3.352 cu in (54.93 cc)
- Bore: 1.62 in (41.2 mm)
- Stroke: 1.62 in (41.2 mm)
- Practical RPM: 1,500-8,000 | Introducing the first O.S. gas engine—designed especially for R/C! It's similar in appearance to other O.S. 2-cycle engines, with a large number of extra-deep and -thin cooling fins on the crankcase and head. A unique 1-piece crankcase design eliminates gaskets and enhances strength and precision. A unique front-mounted carb, however, provides several performance benefits. - Better carburetor cooling, for more consistent engine runs and high performance.
- Requires shorter standoffs, which results in more secure installation (mounting) and less vibration overall.
- Very 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 uses a microcomputer programmed for optimum spark advance. Magnetic sensors on the crankcase and prop drive detect ignition timing. The IG-01 also detects and compensates for wet plugs, ensuring quick starts. Designed to accept a wide range of input voltages, the IG-01 requires minimal current in standby mode and features a low-voltage warning (intermittent engine operation). Other benefits include: - No oil seal is required, eliminating rpm lost due to additional friction.
|  A front-induction, rotary-valve crankshaft, which ensures that the valve is opened and closed for optimum timing. |  Massive front and rear bearings, for longer life and maximum power output. |  A thin, high-performance piston ring and high-strength aluminum alloy piston, for reduced break-in and high compression from the very first run. | | | | | | |
