Hi. Just got a vision 2 plus. It has 3.04 firmware. It flies great like it is. I know there has been several updates since then from
What I have researched. Should I update to the newest 3.14 or leave it alone? Also is there any advantages to updating. Will
It increase speed or possibly handling?Hate to sound like a idiot. Lol. I'm just new to these and learning. Haha.
