Step 31: Final Thoughts
To take flight videos, I spent $5 on a keychain video camera like this one. They are cheap and lightweight. Do not use velcro to mount the camera since the vibrations will ruin the video, use tape instead.
The frame kit comes with a camera attachment, you can attach a small servo to it, but I didn't use it. Also, apparently this helicopter landing skid is a good match for the frame.
My instructable focuses on + configuration flying, but you can easily convert your quadcopter to fly in X configuration. It requires some reconfiguration and recompiling of the source code. The circuit board needs to be mounted at 45 degrees. The landing skid needs to be re-mounted at 45 degrees (the frame kits have slots and mount pieces already for X configuration mounting).
You probably have seen two of my flight controller circuit designs. My designs usually allow you to add in magnetic compass sensors and barometric air pressure sensors. These sensors can be used to let your software get heading and altitude data, which can aid in keeping the quadcopter facing one direction and stay at one altitude. GPS can also be added. The combination of these extra sensors can help with autopilot capabilities. AeroQuad code and MultiWiiCopter code both have some support for these sensors.
