I'm working with an arudcopter for my senior computer science design project. I was testing the auto mode for the first time today. It was a simple mission to fly to 4 waypoints at alt 10 (is this feet or meters?) set in Mission Planner. The copter immediately moved towards the first waypoint and climbed quickly, but quickly after that it lost altitude and flew inches off the ground toward the next waypoint before crashing. Why would the altitude not hold even close to what was set? Is the pressure sensor that inaccurate that it would cause it to crash?

Hello, I present the same problem of yours, that way you covered the barometer to fix it?
Does the copter have good 'Alt Hold'?
Have you tuned your throttle rates to give good 'Alt Hold'?
Do you have a sonar?
The units of height are setup in the Mission Planner, so check there to see weather it is feet or meters, 10 feet is pushing your luck with only barometer.
Have you put the foam guard over the barometer?
You need to get 'Alt Hold' working well before attempting an auto.
