"4.7 Streamers and string are provided by the CD to ensure uniformity. Crepe paper and cotton string are recommended. Streamers will be thirty (30) feet long and no less than five-eighths (5/8) inches wide and no more than one (1) inch wide, attached to the model by a cotton string extending at least five (5') feet from the tail of the model. (At the discretion of the Contest Director, alternate streamer materials not meeting these specifications may be used if weather conditions prevent the use of standard streamer material)."
