Wing Span : 96 inches
Wing Chord : 12 inches
Length : 73 inches
Power : JBA46-ABC x 2 units

Flight Review
The airplane was maiden on 15 May 2009. As today she had 6 sorties. Airborne at about 10ft with half throttle. Fly slow and easy. The wing's polyhydral really reduce stall rate and add control for slow maneuver. If you are going for some scale like flying, then this is an airplane suitable for you. The construction is not intended for aerobatic maneuver.
