A detailed description of the Triskelion kit can be found here.

This list provides you with some information that can help in the assembly and launch of the Triskelion:

• The Triskelion comes with a gluing jig.   This is assembled in Step 1 of the instructions and involves gluing a large thick ring to the Fin Pattern Sheet.  This is then used to hold up the body tube when gluing the fins on.  With this jig, it is possible to glue all of the fins on in one step and then let them all dry at once, greatly speeding up assembly.
• NOTE: Before placing the model onto the gluing jig, it is important that you place a layer of clear cellophane (like Saran wrap) over the entire pattern.  This will keep you from accidentally gluing the rocket or the fins to the pattern sheet.
• Fin Tips: the fin tips that are included with this model are for decoration only and are NOT required for safe flying of the Triskelion.  If the are omitted or (as is more common) one or more fall off before launching, it is not a problem and will not interfere with the flight of this model.
• Toothpicks: However, if you use the fin tips then the toothpicks that come with the kit are required as they help strengthen the tips for flight.
