"The Wright Bat Vertical Flying Machine Wilbur and Orville Wright (you've heard of them) played with a wooden version of this toy in 1878. Their father, Bishop Milton Wright, bought it for them as a gift. Wind the rotor and let go - it flies up! Tie a light plastic ribbon tail to it as a stabilizer. " Hi! I've been wondering how to reconstruct this model flying machine! Can anyone give me a few pointers/guides?
