The YS 60SR is YS’s high-performance 600-class nitro helicopter engine, delivering a significant boost in power and torque thanks to its increased 9.95cc displacement. Designed to offer performance levels approaching those of a 700-class machine, the YS 60SR gives pilots stronger pull, faster response and more authority during aggressive 3D flying.

Featuring the same mounting pattern as the YS50ST and YS56SR, installation is straightforward for most 600-size nitro helicopters. YS’s proven fuel-regulator system ensures smooth, consistent operation throughout the entire RPM range, while the three-needle carburettor provides more precise and flexible tuning. A balanced crankshaft further improves smoothness and reliability, making the 60SR ideal for demanding pilots.

The YS 60SR is also designed to run well on fuel mixtures containing 15–30% nitro with no need for head-clearance adjustments, making it easy to operate and tune. Lightweight, powerful and extremely refined, the YS 60SR is an outstanding choice for modern 600-class nitro helicopters.
