Dragon72-1 Dragon Ornithopter : 14th　Flight Test

Thrust was Ok.
Thrust is enough.
I can steer Dragion72.
But, Lift is small.

In this wing shape, a wing area of a side of the body is small.
I lengthen the body in order to increase an area of this part　and do up lift.


Wing 20mm
Gear Center-Arm point 11.5mm
Length of Arm 58mm (New Arm which can set length)

Reinforcement of Articulated wing connector rod by 1.6mm Carbon rod

Battery 1000mAh3cell

Length 178cm
Weight Now 745g
battery Lipo1000mAh3cell 84g
Total flight weight 829g( no legs)
