Overall, I think this product was successful because it worked and it flew from side to side(Left to right). Also, it did not break when you spin it fast or slow. The only way that is not successful because I did not have time to add the airplane, I added the plane in the picture so I did not add the airplane on the stick
If I did this again, one thing I would do differently is to change my material that holds the stick into the wood so it would not wiggle so much and I would make it a bit more stable. Also, I would add the airplane to the stick so it can fly side to side.
My biggest success was that the cranky contraption works and it doesn’t break and it works well, it doesn’t get stuck and have to move the wire back and spin it again.
