I bought this gimbal and when I first hooked it up to my phantom 1, it worked well. The second time I powered it up, it began to behave erratically. I hooked it up to my mac and used the 2.2b2 software and tried calibrating acc and gyro but it did not help. I know it is an inexpensive gimbal but I really don't want to have waisted $65. Any help would be appreciated. Thanks, Mark
