GT55 O.S. Engine Gas Engine

Introducing the first O.S. gas engine?Xdesigned 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.
