Resistance is constant in a DC circuit, no? I think I understand what you mean though. I'm kinda embarassed I don't know this stuff. (I'm an electrician, but we very rarely deal with batteries and their ratings.)

A rule of thumb I heard was that when you hit about 5x the voltage in amps, it's time to add a cell.

Edit: I see it's probably the 48" Edge
Yeah, it's a $1.5.

I plan to do 3D with it, and I do a bit already, if 15-20 second hovers and harriers count. The wind hasn't been cooperative for any flatspins or the like, so I haven't been doing too much in that category.

I see myself possibly getting something in the 60" range in the near future, thus my curiosity about the 4S swap. It would be nice to have everything running on the same pack.

60" range is generally a 4s 3300mah at minimum... that would be pretty heavy packs for a 48" Edge. I guess you could run two smaller packs in parallel on the bigger bird. Too much trouble VS savings IMO.

Yeah, I just looked at a 58 Edge, and the bottom is a 3700 mAh 4S. I thought it was a little lower than that. Guess I'd just as well go 70+ and run two 4S series....

Now THAT is more like it! 74" Edge is one of the baddest ass looking planes ever... it was gonna be my next had I not scored an 87.

If you don't want to solder, look into Anderson Powerpoles, I would go that route if I was starting out now. A lot of folks (including me) have had good luck with Gens Ace batteries from hobbypartz.com, you could also look into Haiyin batteries.
What kind and size of connectors will I need for the Hacker A30-12XL to ESC.
(thanks)

Just swapped in an E-flite servo from my heli. Not the greatest, I'm sure, but it feels alot better already. The Hextronik servo felt like a ratchet when I moved it by hand....

Much Much Much smoother control, and I also made the arm a tad longer, so it will now throw a full 45 degrees. Waiting for the epoxy to dry, then I'll trim it up and hope for some decent weather tomorrow.

or you can get more 3s 2200's and run two of them in series for the 58 like me and a few others do. its a great way to go. i have 12 of these packs to keep the 48, 57, and 58 in the air. 7X planes get 6s 5000 packs so one day i can double them up for an 50cc bird. i would avoid going up a cell and dropping the prop size unless you are running a 15" or 16" prop. my 48 loves the 14x7 on 3s. running a motrolfly though.

I run the 14 x 7 as well, and I guess my Edge loves it too, but I don't have anything to compare it to. I may end up going the series route when/if I go bigger.

Thanks again for the input guys.

woooh... finally made a decision to migrate to power poles... (hate soldering, cant do anything about it! ) now im scratching my head, will 30A powerpoles be enough for 4000 25c 4s batteries? (for extra 57...) since i read that 30 and 45 uses just different housing... or i'd be better emailing them and swapping out to bigger powerpoles? and what about paraboard? is the only way to get 6 adapters?

I set one of these up with powerpoles to use with a paraboard

45Amp power poles for everything. If the wire is too big to fit then go to 75Amp or direct solder (or remove some wire strands depending on application), if the wire is too small to get a good crimp double it back on itself.

That's what I do anyway

use the paraboard for balancing....the parallel balance cables that progressive has are junk....they will fall apart in your hand but the discharge balance harnesses are sweet....i use the PP squid then plug the balance leads into the paraboard
