I've attached an image of the quad I'm working on. Also, I've attached an image of the Rel Alt and Alt fields of a recent flight of the quad. When in loiter, the quad does not seem to be following my commands. I'm not sure if this is a basic problem with barometer, or there was something wrong with my initial calibration. If a log file is needed to narrow this down, I'd be happy to supply it.
Any thoughts?

Even though I performed a Compass/Mot calibration (successfully), I thought that perhaps there might still be an EMI issue with the motors and ESCs.
So, I installed a capacitor onto one of the spare outputs of the APM. Now, I have a working quad. I've attached images of the GPS RelAlt logs and the BARO Alt logs with and without the capacitor.
If anyone has any insights, I would be happy to hear them. I was somewhat leery of adding the capacitor onto the APM outputs as a result of negative experiences of others, but adding the capacitor seems to have calmed this quad down.
