Hey guys, this is my first thread on this site (or any RC site for that matter). I own a XTM XT2...and i'm using the factory Pistol grip remote. My question is about the volt reading on the remote. I'm too lazy to buy AA rechargeables and a charger so I just use your standard AA batteries...I notice that the voltmeter obviously goes down the more I use it...and right now it is at 10.9v's....how low should I run the batteries before replacing them??? Thanks.
