**O. S.® ENGINES GT55 GAS ENGINE with ELECTRONIC IGNITION

This engine is for airplanes, but we expect a heli engine to follow at some point.



Introducing the first gas engine from O.S.!

The O. S. GT55 Gas Engine with Electronic Ignition is a real first for the O. S. Engine line. With a reputation for producing quality engines at an affordable price, O. S. takes the market by storm with the introduction of their first gas engine. Similar in appearance to other O. S. 2-cycle engines, the GT55 Gas Engine features a large number of extra-deep and thin cooling fins on the crankcase and head. A unique one-piece crankcase design eliminates gaskets and enhances strength and precision. Another performance benefit is the IG-01 Capacitive Discharge Ignition. Developed from specific O. S. technology, the IG-01 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 stand-by mode and features a low-voltage warning (intermittent engine operation). The front-mounted carb provides better cooling for more consistent engine runs and high performance, very simple, direct installation of the throttle and choke linkages and it requires shorter stand-offs, resulting in more secure installation and less vibration overall.

• A front-induction, rotary-valve crankshaft ensures that the valve is opened and closed for optimum timing.
• No oil seal is required, eliminating rpm loss due to additional friction.
• 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.

Let me get this right. This is going to be a Heli engine?

Full Throttle

hmm amaizing.what a....keep it up.
thanks

I had just read an article in RC Heli about a new Century Heli with a gasser motor. The article made mention for flight time of over 20 minutes per tank. I was actually considering it. Not that OS is working on a gasser motor I may consider buying an Align. I've been flying electic since day one. My on issue with electic is the flight times. Just about the time I get comfortable, I have to switch lipo packs. This would give me time to get comfortable, hover, fly a few circuits, experiment and still ahve gas left over.
Hmmm, my next heli may be a gasser after all.
Consider the cost savings compared to electric.. I've got over $200 in lipo packs for my Rex 450 and over $2000 in lipo packs for my Rex 600.
