Step 2: Build your rocket (mostly)
This tutorial is made under the assumption you can build a model rocket. Most kits are not difficult. The Estes Reflector is good for beginners as it is Skill Level 1.
Following the instructions that came with your rocket, build the rocket but leave all the pieces of the payload bay untouched and unfinished. These pieces include: nose cone (top), payload bay tube, and payload bay base (bottom). These parts will need to be modified to accommodate the keychain camera first. Do not attach the eye screw to the base of the payload bay. I attached the eye screw when I built my rocket, but it will save you some trouble if you attach the eye screw after the modifications are complete. Also, do not paint anything yet.
