Hi guys! I've been flying for a month already and I wanted to test the IOC fly modes so I downloaded the Naza assistant and plugged the Phantom in my computer. I didn't even know what version I had, everything is working fine so I didn't want to upgrade the firmware and may be have some issues after the upgrade. Unfortunately I can't change anything in the Naza Assistant until I upgrade my Phantom. I read about some issues with the 3.16 firmware version. There's no way to enable IOC fly modes without upgrading to 3.16? Is really risky to upgrade the Phantom? I'm kind of afraid that something is going to fail. Thanks!!!
