You could try it, but it wouldn't be recommended. Streamers are the recovery system of choice on the windier days. When in doubt, ask the RSO for help in selecting an engine. At our High Power Launches the ceiling is higher, and a waiver table will be available at the launch for you to check your models compliance. Anyone can fly at NIRA events.
Membership is open to any persons interested in sport rocketry.
However, if you want to become certified to fly high power motors you must be a member of either organization. A membership form for the NAR can be found at the NAR Web site. We encourage you to visit the NAR Web site and strongly recommend NAR membership as a good investment for the serious sport rocket flyer. You may be covered by your homeowners insurance, but you would be wise to check with your agent. Insurance is provided through the NAR for individual members, and the club is covered at all launches run by the club.
