Or you can cheap out and use 150 for $0.99 bamboo skewers, some paperclips and shrink tube. I zip tied a tooth pic to one of the paper clips that I made too long and was flexing.
and Wing Reinforcement:
I split them lengthwise with a razor blade, and then glue the strips to the leading edges. You get reinforcing and a rounded leading edge in one operation.
And an awesome reinforced fuse.
