MAIN GEAR CASE UPGRADE
FOR ALIGN TREX 550/600 ELECTRIC SERIES HELICOPTERS

Item Number: AT550/600-MGC
Installation Diagram:  CLICK HERE

Models: all ALIGN TREX 550E, 600E, and 600ESP series (replaces stock Align part #HN6064).

Note: the T700N Main Gear Case for the ALIGN TREX 550E/600E/600ESP electric series uses the stock ALIGN TREX 700 Main Gear (HN7019-1, need to purchase separately), which gives tremendous benefits to the 550/600 designs including: increased headspeed (164T versus 170T), increased gear teeth engagement, and significantly increased strength due to the taller gear and higher contact surfaces.  This upgrade is a MUST HAVE for high-power, high-voltage setups to prevent stripping of the main gear during flight and hard 3D maneuvers.  Please review the installation diagram for critical information on proper press-fit installation and positioning of the one-way clutch bearing for optimal gear alignment.
