Fuselage:
Traditional balsa/plywood structure laser-cut and reinforced with Kevlar® and carbon. The removable composite cowl and top fuselage section provide ideal access to the power system and RC electronics. The engine mounts to a strong rear-mounted plywood engine box.
Wing:
Two-piece wing with semi-symmetrical airfoil, fully sheeted balsa finish, and a strong carbon joiner tube. Ailerons and flaps are each driven by dual high-torque servos for maximum control authority.
Tail Unit:
Lightweight all-balsa construction. The horizontal stabilizer is two-piece, mounted on a carbon tube. Elevator halves are driven by individually mounted servos with short, stiff linkages. Rudder is controlled via pull-pull cables.
Landing Gear:
Carbon main gear, durable Dural tailwheel assembly, and large balloon wheels ensure stable ground handling and rough-field capability.
Recommended RC Equipment:
- 7–9 channel computer radio system
- 7–8 high-torque standard-size servos (20–40 kg/cm)
- Fast servos strongly recommended for aggressive 3D flight
- Independent mixing for ailerons, flaps, and elevator halves
