    • The rotorhead is constructed of a CNC machined metal yoke and reinforced heavy duty plastic blade grips.
    • Floating style feathering shaft with triple bearing support including thrust bearings.
    • CNC machined, full ball bearing Bell-Hiller mixer lever.
    • Adjustable Bell-Hiller mixer to achieve the preferred mixing ratio.
    • Stable main rotor blade grips with 5mm rotor blade bolt.
    • Blade holder with 14 to 18mm width allows the use of rotorblades from 12 to 18mm blade root.
    • 29g aerodynamically balanced flybar paddles for sport and 3D aerobatics.
    • 10mm hardened rotor shaft.
  • 600 Size Flybarless
    • Full CNC aluminum construction.
    • Integrated washout hub.
    • Includes 92 durometer head dampeners.
    • Stable main rotor blade grips with 4mm rotor blade bolt.
    • Blade holder allows the use of rotorblades with 12 blade root.
    • 10mm hardened rotor shaft.

Control System

  • Electronic CCPM with three servos.
  • Electronic CCPM 120° configuration.
  • Push / Pull hinged double ball-bearing bell cranks.
  • Double ball-bearing pitch levers.
  • Plastic pre-molded pitch compensators for proper linkage positioning.
  • Double ball-bearing, CNC Machined Swashplate center with reinforced plastic out control linkages for 120°.
  • The swash plate is hinged with three servos to support 120° CCPM.
  • The control servos employ a push/pull system ensuring all the power is transferred to the swashplate in a unilateral direction.
  • A total of 28° pitch range.

Drivetrain

  • Various gear ratios possible.
  • Spiral cut main gear provides additional contact service area for maximum load bearing and quite gear operation.
  • Sleeved autorotation main gear and hub with adjustable backlash.
  • Stable 15x24mm clutch bearing support by ball bearings.
  • One-stage gearbox offers the best minimal friction loss.
  • Constant driven tail rotor.
  • Heavy duty automotive grade belt driven tail is more crash resilient and lower cost.

Canopy

  • Blow molded high impact resistant canopy.
  • Tinted, high-gloss windshield.
  • Streamlined design for the fast forward flight.
  • High tech professionally designed pre-cut decal set with highly visibility.

Main Frame

  • Extremely stiff G10 or Carbon Fiber main frame with CNC machined bearing blocks.
  • Carburetor fuel level located at centerline for smooth engine operation in all flight attitudes.
  • Large 300 ml tank for long flight times.
  • Separate front and rear frame allows lower cost and easy replacement.
  • H-Frame with cross member design offers reinforcement in all three axes.
  • Extra long front trays offer convenient access to secure electronics.
  • Heavy duty low profile high impact-resistance landing gear accommodates hard landings.
  • Engine plate is CNC manufactured from a single piece of aluminum.

Tail System

  • Triple bearing supported tail blade grips including thrust bearing.
  • 140° of tail pitch range offers extremely fast tail response.
  • Triple ball-bearing supported hardened output shaft.
  • Integrated vertical fin into gearbox offers rigidity as well as weight reduction.
  • Tail boom mounted tail rotor servo for minimal slop.
  • Straight carbon rudder control rod offers maximum direct control.
  • Ball bearing tail rotor pitch bridge for linear tail rotor control.
  • Hollowed out attractive horizontal fin offers weight reduction.
  • Extra large 513mm bearings in the tail rotor gear box output.
  • Sturdy 25mm extra lightweight tail boom.
  • Tail boom struts made of lightweight aluminum.
  • Impact-resistant and lightweight 4.5g 95mm tail blades.
  • Hardened tail rotor shaft.
  • The tail servo is mounted right on the tail boom, thus there are no corrections to the rudder control linkage during disassembly of the tail section.
