T-Rex 700XN from Align


The Align T-Rex 700XN Nitro Helicopter Combo is a refreshing release on a mostly classic design found deep within T-Rex standards. Utilizing proven components from the 700X Electric helicopter, direct to swashplate concept has been moved over to the nitro frame, along with the excellent 700EFL Flybarless Rotor Head. Update design concepts include a narrow frame design that decreases gear wear and frame flex in flight in the most demanding maneuvers, an engine stack moved further forward allows for the fuel tank to be placed directly under the mainshaft which ensures that CG does not change from start to end, and lastly a new steel alloy clutch liner allows for incredible power delivery and improved lifespan. 


  • Direct to Swash Servo Control
  • Narrow Frame Design
  • Steel Clutch Liner
  • CG Neutral Fuel Tank Location
  • 700EFL Rotor Head
  • Nitro Specific "Blonde Yellow" Rotor Blades
  • HV Voltage Regulator
