Jim tried out the Vortex Rocket Set from Quest. It has everything you need to get into the great hobby of model rocketry. As you can see by the video, you do not need a great big field. Kids LOVE rockets. The power, the thrill of the landing, the launch - is everything you need to get them out of the house! Estimate apogee to be 400 feet with this rocket and a B6-4 motor.
