Here is a Major Matt Mason satellite launcher that comes with three rotor type propellers. It is in working condition. It is designed to have a paper bang cap inserted in the spring loaded mechanism. The rotor is wound onto the shaft. When the string is pulled the cap fires and the rotor takes off. The launcher can be angled. The rotors don't travel very far. Some of the rotor blades have come loose from the outer ring. The action figure in the photo is just for demonstration and... is not included with the launcher. Please check my other auctions for more Major Matt Mason stuff. Please e-mail any questions.
