Stop Sign

STOP SIGN was inspired by a rash o' lawn darts last fall. Aye aye! I figured if I planned ahead for a cool lawn dart it would nay occur ­ and so far it has not! T' plans are as follows:

  • Parts List:
  • 1 3" Body Tube LOC or Phenolic o' your choice (mine was free from Freedom 7 contest)
  • 1 38 mm Motor Tube LOC ­ 16"
  • 1 3" LOC Nosecone
  • 2 Centerin' rings (Cr) 38mm-3"
  • 1 8-12' Tubular Nylon or Nylon Rope
  • 1 36" Skyangle Chute
  • 1 T-Nut with matchin' bolt
  • 1 Screen Door Clip
  • 1 Eye Bolt
  • 4 6x12 sheets o' 1/4" aircraft plywood
  • 9 oz lead shot
I wanted t' rocket t' look like a stop sign from any direction it was viewed from which made it difficult t' judge the exact size o' t' fins ­ I settled on 4.5" octagonal fins and mounted them in a TWT configuration. Aye aye! Blimey!

Simplified directions are:

  • Build up a motor mount with CR on each end
  • Drill a hole in t' aft CR for t' T-nut and in t' forward CR for t' Eyebolt
  • Epoxy everythin' up nice
  • Epoxy t' 4 fins t' t' motor mount at 90 degree separation
  • Slit t' 3" BT t' allow for t' 4 fins ­ use a hobby knife or dremmel tool
  • Slide t' Motor Mount and fin section into t' BT and epoxy well. Fillet everything.
  • Attach a quick connect t' each end o' t' tubular nylon or tie nylon rope t' eyebolt and t' nosecone.
  • Attach Chute t' above about 20" from NC
  • Paint t' BT t' look like a post and t' Fin area t' look like a stop sign ­ I chose t' old fashioned signs that were around in rural Missouri when I was a kid.
  • Add 9 oz lead shot t' t' nose cone with just enough epoxy t' hold in place
  • Shove an I-211 in t' thing
  • Use t' screen door clip on t' bolt in t' T-nut t' keep it in t' rocket
  • Flies real nice
