Sources report that YS is keeping up in the “Crazy Heli Engine race” and is planning to release a new 60 sized Heli engine soon.
The new YS 60 SR heli engine is still a mystery as no formal information had been released to the public yet.
From examinations of photos and discussions with experts it seems that the new YS 60 SR engine will be based on the successful YS 56 engine but will probably have an improved carburetor.
According the photos it seems that the carburetor had been redesigned and even the needle settings are different on it.
We will keep updating our readers as more information is released.
