Receiver Mount Upgrade for ALIGN T-Rex 700/800 Electric Series Helicopters

Product has been archived, and is no longer available for purchase. This page is for reference only.



The Receiver Mount Upgrade is the optimal upgrade for the T-Rex 700/800 series, providing excellent strength characteristics to protect the valuable electronics in the front of the helicopter; while also solving the problematic, tail-heavy center-of-gravity (CG) nature of the stock helicopter. With an integrated battery tray rail system and a dual-captured strap slot design, the pilot can now adjust the location of the LiPos for optimal CG balance. In addition, the shear-strength of the Aluminum front rails will support the stock plastic-rails that are prone to break in high-power, hard-3D flying conditions; giving the pilot peace-of-mind to fly the helicopter to its utmost potential.

Important Notice: The T-Rex 700E (V1/V2) Series main-frames (H70041 and H70042) have an extended battery rail that interferes with the AT700E-RMU design. This document (PDF) provides instructions for the required modifications.

The T-Rex 700E DFC main-frames do not require any modifications and are an ideal match to the design.
