Information For The SLS Javelin
The Javelin was introduced in the 1965 Centuri catalog. It became one of their
signature beginner kits and was included in at least two of their multi-kit
outfits. The Javelin was Centuri #KC-31. Semroc introduced a full scale
Javelin in 2003.
The SLS (Semroc-Large-Scale) Javelin is a 175% upscale of the original
Centuri kit. Using SLS parts a precise upscale is possible using much more
rugged parts than the original sized Javelin. The SLS Javelin uses precision
laser-cut basswood fins instead of balsa for additional strength. An 18" Nylon
chute is used instead of the original poly plastic. The body tube is laser slotted
to match the through the wall (TTW) fins. The original Javelin had a rubber
shock cord and is replaced with Kevlar cord and elastic cord for greater
strength and reliability. A 24mm motor mount adapter is included to increase
the selection of engines that can be used.
