OS GT15-HZ II 2ST GLOW HELICOPTER WITH POWERBOOST PIPE 15HZ

The O.S. GT 15 HZ II 15cc petrol engine is designed for helicopters of the 700 class. Thanks to the new enlarged cooling head and additional cooling ribs on the crankcase, the engine runs cooler by approx. 12 ° C and can be adjusted much better than the previous version. Likewise, the cylinder head has been revised, which is good for the running behavior.
