Best Rocket kits Ever! Great quality. A mid-power rocket acts and sounds like a high-power rocket. It is a reusable cost for each flight and the overall cost of ownership. I recommend all Aero-Teck rocket kits for this reason. I wish they made more model options. I would like to see a military rock series. Be advised. These rockets fly high and fast. I have launched three and was not able to recover due to the launch location, and it was a certified NAR launch site. But I do use top power. Go big or go home, and I went home with one less rocket each time. lol, have fun... building them is just as enjoyable.
