RE: 4.8 V to 6.0 V
Exactly! It is indeed meant to deal with "momentary" voltage drops due to electric motor usage (servo's). I do indeed hope it works, I didn't just pick that thing up at Radio Shack, it's a Spektrum branded part sold to deal with this very problem. AT least that is what my LHS is telling me.....
I have had issues with brown outs all last summer, only one resulted in a lost plane...to low / not enough air-speed to recover. I pulled the 4.8v 1100 mah pack out and had 3 more flights with it in my Eagle 2 on 72mhz.
I agree 6v packs are the way to go when you can, but I have way to many perfectly good 4.8v packs that are comfortable inside .40 - .60 size planes to just throw them away. I do hope it helps, because if it doesn't I'm going to dump all my Spektrum equipment and get that cool looking Aurora 9 / Hitec recievers!
I'm not even sure how that Spektrum capacitor works exactly...is it constantly storing and releasing power? Perhaps it's just enough to level out those voltage fluctuations due to servo load? Either way way we will find out! It's mounted and ready to go.....as soon as the field dries out a bit!
