I lost a plane to the Spektrum brown out last year......I was flying low when it happened, not enough time to recover. Worst part is, the battery seemed fine.....even after the crash. Had a momentary drop in voltage while flying the plane pretty hard?
I found one of these for $5 at my LHS. Called a ''Voltage Protector'', sounds like it might eliminate the brown out issues? I guess we'll see! (as soon as it quits raining).
That's NOT going to help. According to the JR/Spektrum rep (Danny Snyder) it's designed for small electric cars and the like (carpet racers). It's been the topic of many threads and simply can't store enough energy to be worth the price. It's designed to suppress the spiking caused by electric motors. It's NOT intended to prevent brownouts.
Your best bet is proper batteries for your project. I wouldn't even try a 4.8 pack. I'd get a 6v pack with good capacity (varies by project) or the new A123 batteries. And ALWAYS monitor your batteries and recharge before they get too low. 4.8 batteries get too low too soon, even bigger ones.
