Fully read through the instructions printed on the template before cutting.  You will use the entire sheet - there are no "leftovers".

Next, use the launch tube from the launcher kit as a mandrel to make sure it is the right size.  Alternately, you can get 1/2″ PVC pipe at Lowes or Home Depot, and cut it to 12″ lengths to use as a mandrel.  This works well when working with groups.  We also sell sets of 10 pre-cut mandrels in our shop section here.

You will also need a roll of clear packing tape so the graphics printed on the paper will show through.

1.) If you wrap the template too tightly around the forming pipe, it will be tough to remove from the forming pipe and tough to fit onto the launch tube.  Even if you get it onto the launch tube, it is much more likely to make “Confetti” (blow off the nosecone) when you try to launch it.  If it is too loose, it will not fly as high, as the pressure will escape out around the gap.  A nice sliding fit is best.

2.) I like to trim the leading and trailing edges of the fins.  Besides looking good, they are less likely to fold over with the high g forces of launch (sometimes over 100 g's) and upon landing, which can make the rocket not fly as straight.  They are also less likely to get caught when falling through tree branches.

3.) Experiment with the fins – how well does the rocket fly without fins?  With one fin?  With two?  Can you make the rocket fly well with only two fins?  How about where the fins are placed?  What if the fins were in the middle or the front of the rocket?  If they are not mounted straight?  If they are made large?  How small of fins will still work? Have fun experimenting with them.

Please give it a try and let us know what you think.

Now go launch something!
