This is an optional KDE Direct TREX 500 Motor Mount Upgrade, and is intended for use with the Align T-Rex 500E/ESP series helicopters. This is a direct replacement for the stock Align part AGNH50042. The KDE Motor Mount Upgrade provides an excellent platform for all M3 x 25mm spacing brushless motors and was specifically designed for the latest high-performance motors, such as the KDE Direct 500XF-1450 HP Brushless Motor. The design incorporates a lowered bottom surface for the motor mounting platform and a wider central pocket; allowing the user to install a wide-range of available motors without any modifications required for the carbon frames. Also, with the increased central pocket diameter, the design can accommodate up to 18T (MOD 0.6) pinions without any issues for high-performance setups.
Weight: 12 g (design is FEA optimized for maximum strength and minimum weight)
