OS MAX-37SZ-H RING (20M)

Description:

Designed to deliver premium performance for 30-sized machines, from extreme aerobatics to stable hovering!

• The crankshaft has been re-engineered to reduce vibration, resulting in smooth power across the entire rpm range.
• A larger rear bearing boosts power even more.
• Features the same mounting pattern and muffler dimensions as the 32SX-H, for easy installation in most 30-size helis.

For easier access when making adjustments, the idle needle is positioned on the same side as the main needle.
