KEY FEATURES
Forged Carbon Main Frame
Constructed from Forged Carbon, it combines extremely low weight with superior structural rigidity, ensuring excellent responsiveness and in-flight stability.
Single Stage Transmission System
The drive system uses a Gates GT3 toothed belt, offering smooth performance and exceptional quietness, contributing to the overall acoustic cleanliness of the model.
Dampening Tail Boom Support System
The tail boom is supported by variable-hardness rubber dampers, an innovative solution that effectively cancels out the typical vertical oscillations seen in models operating at low rotor RPMs.
New Cyclic Servo Layout
With the new servo layout, the 3 servo linkages are equal and maximize the precision of 3 cyclic servos
Unique Tail Servo Mounting Position
Tail servo located inside the tail boom allows the carbon tail push rod become “invisible” inside the tail boom as well.
New Design S737 F3C Main Blades
Equipped with the latest F3C blades developed in collaboration with World Champion Ennio Graber.
One Way Bearing On the Main Shaft
The one way hub is assembled on the main pulley and work with the main shaft through a steel bushing.
Quick Connectors And Battery Release
The battery tray features integrated connectors for quick, secure, and tidy connections. The battery is inserted from the rear without removing the canopy.
F3C-HPS Head System With 35mm Blades Grip Arms
Refined through hundreds of test flights, the rotor head geometry ensures maximum precision, progressive control response, and predictable handling.
New Tail Pitch Leverler Design
The carbon rod is positioned inside the tail boom, giving it a clean, aerodynamic look.
PACKAGE INCLUDES
- Genesis F3C – SG767 Helicopter kit with:
- 21T motor pulley (other sizes available separately)
- 2 battery trays with integrated connectors
- S737X F3C main blades (240 g)
- S110 tail blades (110 mm)
