True for APCP, but foot-long chunks of 1" PVC (1-1/4"OD) are perfect fits for
38mm UC-valve hybrid motors and -- with five minutes' hacksaw work -- will
power some nice midlevel flights. Grains don't come much cheaper than that!
Of course,nitrous is an out-of-pocket expense unless you're a dentist. And,
yep, it helps to know someone with GSE.
Then there's sugar motors. One of these days I swear I'm gonna build a bird
from nothing but supermarket OTC stuff!
Come to think of it, Bill Colburn told the story of someone who built a hybrid
motor using a cored-out pepperoni for the fuel grain. It also occurs to me
there's nitrous in them thar whipped-cream cans...

I have heard many a time that making your own motors is rarely a moneysaver.
