In models with frame-mounted gyro servos, routine tail drive belt adjustment also requires changing the tail linkage. The Axe 400 simplifies the job by mounting the servo on the tail boom — no linkage adjustments needed!
Your battery pack straps into place on an easy-access tray, located for a neutral center of gravity that enhances 3D performance. Battery shown not included. Requires: 11.1V 2000-2500 mAh LiPo battery.
The resilient frame design — consisting of two injection-molded plastic pieces joined by screws — keeps on-board components easily accessible while providing the structural integrity needed for accurate maneuvers.
The quality of included electronics — and of the Axe 400 helicopter itself — makes this the perfect machine for any pilot eager to dazzle spectators with stunning 3D performance.
The Axe 400 includes the largest power plant of any ready-to-fly heli in its class — a 425-size outrunner brushless motor with built-in cooling fan.
Use the 2.4GHz Futaba 6EX radio to fly other aircraft equipped with a FASST receiver — and extend the advantages you enjoy from this system throughout your entire fleet.
The standard-size footprint of the HM4000 Heading Lock Gyro provides mounting stability, avoiding the "twitchy" performance of sub-micro gyros that mount on edge. Dual remote and mechanical gain adjustments increase its flexibility.
Cutting-edge performance demands state-of-the-art electronics — and that's why Heli-Max includes Futaba's R606FS FASST receiver and lightweight S3114 high-torque micro servos.
