I've been zipping around inside the house with this. It is a challenge, getting places indoors without hitting the ceiling or bouncing off of things. I love the "Meow" mode. I have noticed a tendency for this to lose its propellers while flying In the house, it is easy to find the props inside but I'm reluctant to take it outside. Any ideas on how to adhere the props better? Glue?

Put a piece of dental floss between the rotor shaft and the housing.
