Main Shaft Bearing Support for SAB Heli Division Goblin 630/700/770 Series Helicopters

Product has been archived, and is no longer available for purchase. This page is for reference only.



The Main Shaft Bearing Support provides a direct bolt-in upgrade for the SAB Heli Division Goblin series helicopters (including the latest Competition and SPEED version kits). The upgrade is designed to provide a rigid and extremely durable transmission for the Goblin series; utilizing a triple-bearing supported and maintenance-free, sealed deep-groove radial-ball bearing design to support both radial and axial-loads on the main shaft. In this regard, more power will be available for hard pitch-pumps, 3D maneuvers, and autorotations; as well as protecting the integrity of the radial bearings for a long-lasting transmission.
