KDE Direct Performance Boom Support Assembly

This is an optional KDE Direct Performance Boom Support Assembly, and is intended for use with the Align T-Rex 700, Outrage Velocity 90, and other high-performance 700-class Electric and 90-class Nitro series helicopters. The design utilizes M4 mounting holes and is identical in length to the ALIGN TREX 700 series tail boom supports and is a direct replacement for the stock Align part AGNHN7055A.

The KDE Direct 700 Series Performance Boom Support Assembly encompasses a series of specialized design features targeted at preventing the problematic loosening and resultant failure (telescoping) of the critical Tail Boom Support of the 700-class Electric and 90-class Nitro helicopters. Due to the caustic and high-frequency vibration environment of RC helicopters, these upgrades are a necessary enhancement to maintain the structural integrity and performance of the helicopter tail mechanics and control. The Boom Support Assemblies are produced and assembled 100% in the U.S.A.; including the highest-quality, ultra-strength carbon fiber tubes manufactured in the U.S.A. to yield high-stiffness and lightweight characteristics.

  • Vibration Resistant Construction: The assembly utilizes multiple design aspects to provide the strongest and highest vibration-resistance capability, including these critical attributes:
    • Aerospace-grade epoxy bond between all critical components; providing a high-shock resistant and ultra-strength joint (Hysol® E-120HP).
    • Internally-threaded set-screw in the Aluminum Boom Support Ends provide a 360°surface bond to the carbon-rod interior for extreme strength.
    • M2.5 socket head cap screw and locknut retainer threaded perpendicular to the carbon-rod axis for further protection against loosening.
  • Aluminum 6061-T6 Boom Support Ends: Design incorporates precision CNC-milled support ends; providing a vibration-resistant and secure hold to the boom and frames, without worry of failure or cracking due to extended use and repetitive cyclic loading.
