RE: Cons for installing redundant receiver batteries ?
Honestly when was the last time you heard of a RX battery failing in flight? Dying in flight yes, but failing(?) And if you’re out of juice you’re out of juice, dual batts aren’t going to matter. I’ve quit running dual batts, waste of weight. For those who say you can just run two smaller batts to make up for the weight penalty you’ve just doubled your chances of failure. If your plane needs 1400mah and you run two 700mah batts, if one quits you’re still crashed.
