T700 MAIN GEAR CASE
FOR ALIGN TREX 550/600 ELECTRIC SERIES HELICOPTERS

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

Material: Aluminum 6061-T6
Models: all ALIGN TREX 550E, 600E, and 600ESP series (replaces stock Align part #HN6064).

Recommended Accessories:
TREX 700 SERIES MAIN DRIVE GEAR, 115T, MOD1.0
TREX 700 SERIES MAIN DRIVE GEAR, 164T, MOD0.7

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.

Update: the T700 Main Gear Case can be used in conjunction with the new KDE Direct TREX 700 Series Main Drive Gear, 115T, MOD1.0 or the KDE Direct TREX 700 Series Main Drive Gear, 164T, MOD0.7 (need to purchase separately) for significantly increased strength advantages, reduced noise/wear, and alternate gearing ratios.
