The T700 Main Gear Case for the ALIGN T-Rex 550E/600E/600ESP electric series uses the stock ALIGN T-Rex 700 Main Gear (HN7019-1, must be purchased 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 (PDF) for critical information on proper press-fit installation and positioning of the one-way clutch bearing for optimal gear alignment.

The T700 Main Gear Case can be used in conjunction with the new KDE Direct T-Rex 550/600/700 Series Main Drive Gear, 115T, MOD1.0 or the KDE Direct T-Rex 550/600/700 Series Main Drive Gear, 164T, MOD0.7 (must be purchased separately) for significantly increased strength advantages, reduced noise/wear, and alternate gearing ratios. In addition, the new High-Performance One-Way Drawn Cup Clutch Bearing (HF1216) is also available for a strong, bind-free transmission of the power to the main shaft.

SAVE $0.95 when you purchase the Main Gear Case with the HF1216 Bearing.
