Just got this loaded this morning and off to test it.This was the first crash I had that broke something. I have no idea what happened, so I'm hoping someone can give me a few ideas.I have the quad equipped with a point and shoot camera (4oz or so) other than that no changes to the standard frame/electronics. No sonar, no compass. The PID's were set to the default values.Flying in simple mode.I flew the quad to about 5 feet --- it was very stable even in the 5-8 mph wind. Feeling confident in that fact, I took it up to about 10 feet. Then it made a quick 90 degree yaw CCW. It held that for no more than 1 second then it swung back 270 degrees CW --- headed straight for me. I cut the power and it crashed into the driveway breaking 2 landing gear legs.
