Material: Aluminum 6061-T6
Models: all ALIGN TREX 550E (V1/V2), 600E/ESP, and 600E PRO series (replaces stock Align part #H60200 and #HN6064B).

Recommended Accessories:
TREX 700 SERIES MAIN DRIVE GEAR, 115T, MOD1.0
TREX 700 SERIES MAIN DRIVE GEAR, 164T, MOD0.7
TREX 550/600/600N SERIES HP ONE-WAY DRAWN CUP CLUTCH BEARING, HF1216

Note: the T700 Universal Main Gear Case for the ALIGN TREX 600E PRO series helicopter (also compatible with the TREX 550E and 600E/ESP series with components listed below) provides the most universal solution for gearing setups throughout the helicopter series. No more self-tapping screws into plastic, the new upgrade provides a rigid, six-screw bolt pattern for the gear to the Main Gear Case for unreal strength and simplified installation. 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.

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. 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 if replacements are required.
