O.S. 50 SX-H Hyper Ringed Competition Helicopter Engine
I have been running this engine in a Hirobo SDX and so far have put 40 litres of fuel through it. Provides good power on 20% Cool Power Red and 10% nitro. Very reliable when run on the rich side of max power. Has helped me get lots of stick time so has improved my flying a lot.I brought another one just for spares. Will try the 55hz next. I recommend this engine for sure.
