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

• Parts List:
• 1 3" Body Tube LOC or Phenolic of your choice (mine was free from Freedom 7 contest)
• 1 38 mm Motor Tube LOC ­ 16"
• 1 3" LOC Nosecone
• 2 Centering rings (Cr) 38mm-3"
• 1 8-12' Tubular Nylon or Nylon Rope
• 1 36" Skyangle Chute
• 1 T-Nut with matching bolt
• 1 Screen Door Clip
• 1 Eye Bolt
• 4 6x12 sheets of 1/4" aircraft plywood
• 9 oz lead shot

Simplified directions are:

• Build up a motor mount with CR on each end
• Drill a hole in the aft CR for the T-nut and in the forward CR for the Eyebolt
• Epoxy everything up nice
• Epoxy the 4 fins to the motor mount at 90 degree separation
• Slit the 3" BT to allow for the 4 fins ­ use a hobby knife or dremmel tool
• Slide the Motor Mount and fin section into the BT and epoxy well. Fillet everything.
• Attach a quick connect to each end of the tubular nylon or tie nylon rope to eyebolt and to nosecone.
• Attach Chute to above about 20" from NC
• Paint the BT to look like a post and the Fin area to look like a stop sign ­ I chose the old fashioned signs that were around in rural Missouri when I was a kid.
• Add 9 oz lead shot to the nose cone with just enough epoxy to hold in place
• Shove an I-211 in the thing
• Use the screen door clip on the bolt in the T-nut to keep it in the rocket
• Flies real nice
