Ornithopter

The weather has been bad lately so I thought I'd try something different. It's a FREE BIRD II ornithopter. Flys OK in the lounge room but the space is too restricted. I gave it a few flights outdoors at 6:00am one morning before the wind got up. Only used 40 to 50 turns and got about 10 seconds flight time. Weight is 0.2 ounce. The covering is Solarfilm LITESPAN.






Had a quiet Christmas Day today so I built this before lunch. Tried it in the lounge room. Wow! It flys FAST.  It's a MINI GYMELLO RP. I got the plan from Hip Pocket Aeronautics. Weighs 0.8 ounce. I used a Hobby King prop assembly and Undercarriage  that I had on hand so that made construction easier. Litespan covering.
