Wing construction is very conventional. Sheeted Dbox and balsa ribs. Contest grade balsa and hardwood are used throughout the wing with fiber glass re-enhancement in wing tip, join and aileron. This is a "all wood" DLG wing without CF spar.

Additional torsional strength is provided by
- Modified AG4x airfoil (7% thickness)
- 45 degree biased covering (kite material)
- Wing aspect ratio

Tail feathers are solid balsa. Full flying stab with matched CF rod/tube. Detail can be found in Bumblebee XL build thread.

Boom and pod are comercially available from AH.

Ready for maiden this morning ..... more to come.
