FUSELAGE

Two parts joined with 2mm carbon rod or wood toothpick.
Four fuselage variants for common servos:
- Corona 939/929MG - remove small pads - (can be HV version), HK939MG (Hobbyking)
- Hextronic HXT900 : Cheap servo
- BlueArrow D05010MG, similar to PowerHD DSM44,
- Hyperion DS09-AMD,

Servo is mounted from the front and maintained with screws, assembly can be difficult to assemble for "big" servos like Corona and Hxt900.

Backside is maintained by the 2 screws and front by two turns of crystal tape around the fuselage.

ELEVATOR/RUDDER

Elevator is build around carbon rod diam. 3mm and balsa like the original version.

"Croupion" part allow removable tail/rudder by two nylon M3 screws.

WING
Wing

Wing is printed in 3 parts (Aile1, Aile2, Aile3), there is some built-in reinforcement/support inside for small wing joiners (carbon rod 2mm) and main 6mm carbon rod.

Wing root can be added : protect fuselage and add some spacing for linkage.

SERVO LINKAGE

One plastic tube is inserted inside wing root around 20mm long for control linkage.
Control linkage is build using 1mm steel rod, "Z" shape on servo side. Round each tip.

Another small plastic tube for rubber band maintaining wings (also used to balance CG)
