The Specter 700 Ultimate 3-Blade is XLPower’s flagship evolution of precision 3D helicopter engineering, built for pilots who demand the ultimate in cyclic authority, tail hold, and in-air stability. Based on the proven Ultimate platform, this version adds a purpose-designed tri-blade head system, refined control geometry, and reinforced mechanics to deliver a flight feel that’s tighter, faster, and smoother than ever before.

Every component, from the three-blade head block to the balanced tail system, is optimized for the unique dynamics of multi-blade flight. The result is a model that tracks like it’s on rails, carves through maneuvers with surgical accuracy, and still maintains that unmistakable XLPower agility.

From the one-piece CNC motor mount to the tri-point head damping system, every detail is crafted for strength, consistency, and pilot confidence under the extreme forces of modern 3D flight.

Key Features

Precision 3-blade head system for faster cyclic response, improved disc efficiency, and ultra-stable flight characteristics

Reinforced main shaft and spindle design to handle the increased loading of tri-blade performance

Optimized swash-to-rotor geometry (1:1 ratio) for perfectly linear control response

Upgraded tail assembly with revised lever geometry for superior yaw authority and consistency

Enhanced frame bracing and motor mount integration to reduce torsional flex during high-torque maneuvers

Refined damping and bearing tolerances for smoother mechanical feel and reduced vibration

Quick-release battery tray and easy maintenance layout for faster field turnaround
