Recovery Dog Tag
 

I found these key tags at the local builders surplus. They cost only 17 cents each and are available in several colors. I've been using them on all my larger, pricier models. I just scribble my name and phone number and then tie them to the shock cord. The parachute connects to the snap ring. Might pay off someday if I lose the rocket.

That's a great idea.

Besides the motors to use for flights in the rocket, I usually at least write this information on the rockets nosecone shoulder. I guess you could also put the motor information on the rockts dog tag.
