View Full Version : NAR Flight Cards and Recovery Clarification
16th April 2012, 02:30 AM
I printed off the Duration and Altitude flight cards from NAR.org for our contest, but I wondered if we use special flight cards for Spot Landing. Is it typical to use generic flight cards for this and other non-altitude/non-duration events?
Also, in an event such as B Altitude, I assume recovery device specifics don't matter. I know you must have a recovery device of some sort, but, for example, you could use a streamer that didn't conform to the rules specified for streamer duration flights, correct?
Just double checking items that might come up during my first attempt at running a contest.
Thanks for any help!

I'd suggest getting in touch with the fellow who is your regional Contest Board member. They're all listed near the bottom of this page: http://www.nar.org/NARadmin.html
I'm sure others will know, but the guys on the Contest Board certainly do.

There is a place in the bottom right corner of the NAR duration flight card for spot landing. This is what I normally use at MASA contests.
As far as B altitude goes, any "B" powered rocket will work. This is a cut and paste from the July 2010 Pink Book on the NAR website:
20 Altitude Competition
Altitude Competition comprises twelve events open to any model rocket. The purpose of this competition is to achieve the highest altitude.
This competition is divided into classes based on the permissible total impulse of the motor(s).

In response to your question about B Altitude - you are correct in that any recovery system is acceptable as long as the rocket recovers safely. This will be up to the RSO. Certainly it is very possible to build a B Altitude model that is light enough to safely recover on a small streamer. The streamer does not have to conform to any other streamer event rules - thus, a streamer that is smaller than the Streamer Duration standard (I believe it must be at least 100 square centimeters) is perfectly legal for Altitude competition. In fact, Altitude models do not have to be returned unless the RSO suspects an unsafe or illegal flight. Build very light (minimum diameter thin walled tubing such as fiberglass, cardstock or vellum, and a blow-molded nose cone) with thin fins (G10 waferboard or 1/32" ply are common) - just make sure it is stable. Unless you are using altimeters, use plenty of tracking powder that is very visible. Fiberglass pigments and surveyor's chalk are most commonly used.
