Abundant power for 3-D thrills.

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

The crankshaft has been re-engineered to lessen vibration, leading to smooth energy throughout the whole rpm range.

A larger backside bearing boosts power a lot more.

Features the exact same mounting pattern and muffler proportions as the 32SX-H, for easy installation generally in most 30-size helis.
