ORIGINAL: Highflight-RCU I've done my due diligence of searching before posting this and haven't yet found a definitive answer to a question, so here goes: I'm about to make my move to 2.4ghz for the first time (radio ordered not yet received), and I've come across various references to 2.4ghz receivers dropping out when they reach a low voltage point. My experience with 72mhz receivers is that they might get twitchy at some low-voltage point, but you get a bit of a warning that way before you get into real trouble. On the other hand, what I've read indicates that 2.4ghz receivers just shut down, and that's it. So for those with experience, what's the deal, and if the 2.4ghz receivers are different in that way, what do you do differently and/or what precautions do you take when operating with them?
