Haven't had any problems in two months of phantom 2 flying. Today I crashed it twice. Here is what happened. After getting green lights for home lock and go, started up fine, but when I hit up it took off 2 feet off the ground straight into the bushes. Then after a compass recalibration. Test flight at a different place resulted in another low level fly away into the ground. No real damage but something is definitely wrong. My thinking is remote may need recalibration. Help!
