4枚の翼を持つ恐竜の羽ばたき機　MicroRaptor71--Four wing Dinosaur-: Flight and Gliding at Seaside

4枚の翼を持つ恐竜の羽ばたき機　MicroRaptor71--Four wing Dinosaur-: Flight and Gliding at Seaside Microraptor71 do good flight and good gliding. Microraptor71 I steered Microraptor70 by an Inverted V Tail system. This is based on a picture of BBC Planet Dinosaur 2011. https://www.youtube.com/watch?v=-fyxUxGdrns In consideration of new flight posture of Microraptor (by an advice of Mr Michael Habib), I am producing new Microraptor(Microraptor71). Wingtips are thin and legs toward below. https://www.youtube.com/watch?v=SmcqnAWKLJQ 　By inverted V Tail and hind legs opening, wing area becomes big and flight performance becomes better. But when hind legs shut and turns below, flight performance deteriorates slightly. Even if it loses flight performance, it may be evolution to obtain the leg which can walk on ground freely. And the dinosaur evolved to birds. width 119cm length 102cm Body Weight 181g 180mAh3cellG5 18g Total Flight weight 199g Servo: inverted Vtail: elevator & rudder (DS65HB servo *2) Motor: Turnigy 2211 Brushless Indoor Motor 2300kv ESC: Plush 10A Brushless Speed Controller Battery: LiPo 180mAh3cell G5 Control: 3CH (a motor, V tail 2ch) Gear : 66TM0.4 6mmNewGear (Stainless shaft3mm, 3mm ball bearing), First gear: 62TM0.4 , 64P8TPinionWire(with 4mm ball bearing), Pinion Gear M04 14T Film of a wing: Lamagaurd 10 Gliding system : New GLDAB Ornithopter, MicroRaptor, ミクロラプター, robot bird,羽ばたき機, ロボットバード
