For all the talk about back to back flying, I have yet to meet someone who actually does it. Even at a FF you have down time. Unless you fly by yourself and have 1 hour to do it in, you really don't need to have a battery hot off the presses.....a 10 minute interval will save you $$$$ on extra power needed at the field............Ron

+1.

What ide really like to see is an LED battery level indicator for the flight packs, its easy on a nitro to see how much fuel you have left, why not on an electric? Lets say your just doing autos or just hovering round cos your board, if you go by your timer you could still have 50% battery left but no way of knowing!

60% of the time, it works every time!

mah counter Richard, it's in the works

I agree on that to maximize the flight time when your mixing it up

...Once upon a time there were Nitros, flybars and frequency pins...

Nice! I know with the telemetry on the Multiplex radios you can set the timer to go off when the battery has used x amount of mah or a few seconds before I think to give you time to land. Very cool.

I have a secret field that I go to and fly back-to-back when I only have about 1 to 2 hours to spare. It is secret because there are no other helicopter pilots that go there, and there are no kids or spectators who see me flying and pull over to ask questions. If you want to know where it is, I cannot tell you because it is SECRET.

I am lucky to get in 6 flights at my local field on a Sunday morning. And if I pull over on the side of the road and start flying from some abandoned plot of land, there is inevitably either a couple of 12 year old kids or an old man who come over and ask me 1000 questions. Definitely cuts into your flying time.

PL8 works great for me, parallel charge 2 large packs at 35A very quickly. (or all 6 of my smaller packs).
I'll buy another if I need more power, they have special mounts on the side to tie them together and then connect them using a cable and they basically work as one unit. You can have up to 6 connected like that, I believe.
Parallel charging has one more advantage, which people often forget - you save on balancing time as all packs are balanced at once, this can be substantial saving when charging at high C where charging takes 15 minutes and balancing about 3-5.

Great setup, thanks for sharing, I am aiming at pretty much the same setup next season (I'll be using powerlabs 8 instead of ichargers)

That really depends on the packs. High quality packs require very little balancing.

When I'm out with my nitro I do that, especially if there's nobody else out at the field or if I'm pressed for time. There's no way around this advantage of nitro/gas - the real joy is instant availability of power easily and without a large amount of support equipment.

That is, as long as nothing strips or breaks or burns up or falls off the thing... that of course really negates the advantage .

For my 700E, though, I tend to do fairly well with one icharger 3010b, a set of balance leads and either one or both of my deep-cycle batteries depending on how long I intend to fly. My batts are medium quality Align 5200mah 6s's, which I charget at about 2C at the field. This way I'm down for about 10 minutes between flights.

With the 5200's I can fly safely for about 10 minutes (I'm a "sport" flyer and run a pretty low head speed). So if I do a flight that long, the batts on the charger are about halfway done by the time I come back to the table.

So that's acceptable for me, at least for right now. If I had better batts that could be charged harder, I'd just wire my 2 deep cycles in series and max out my charger for a quicker charge time.

But justin's setup really rocks! I love my icharger so far and two of them would really be the business....

With the exception of my H-2000i which I usually store in my PU when not used for other things, I take less support equipment than I ever did when flying liquid fuel. In place of my big bulky flight box I have a Harbor Freight case with two 3010b's and a MW 1500W PS, and of course various wires, etc. It's about half the size of the flight box. For me, electric is a lot better fit, and much more convenient. I charge 6S 5000 batts at 26A each for about a 10-12 min charge time. I never got more flying time in with the glows except a long time ago when I flew the 30's...then maybe.

Hyperion 720 Duo + Honda EU2000 + Dual Meanwell RSP-1000-24's = 8 minute recharge times between flights ... I don't even bother taking my batteries out of the heli anymore.

Now there's an idea! If only they made balance lead extensions!

My iCharger will charge two 6S pack's in 6-8 min's at 30A..
Well I was off by 2 min's ..Took a total of 17:25 min's to balance charge both pack's and balancing add's another 5 min's or so to the charge time so remember that.At the field,I fast charge which knock's off that 5 or so min's..I could back to back fly with 2 flight set's if I want as it will take 10-12 min's to fully charge both of my 6S 5000mAh pack's at the same time.By the time im finished with a flight,my other pack's would be 2 min's away from charged ..

Just watch the end of the video's unless you wanna watch the timer lol..

Watch at YouTube

Watch at YouTube

If someone complain's about waiting 2-3 min's between flight's,they have nothing better to do than whine about 2-3 min's ..Take a drink of pop then a look over your heli which people should do anyway's after each flight and your ready to go..I charge at 13A which take's 22-23 min's too charge and that's back to back flying for me.I need to sit down 10 min's anyway's to give my back a rest or give the other pilot's at the club a chance to fly is someone else is there .All im lacking is a good gen but more than happy with the charge time I get now with it.What I have now for electric is no different than my 90 size nitro's other than I already saved ALOT of money not having to buy fuel and E's have more power.
I love both E's and N's ..If thing's go as planned,i'll have a Chaos 600LE nitro by summer and fly it as much as I do my 700E but not a 700N.Some of you guy's have deep wallet's if your flying a 90 size nitro as much as I fly my 700E.Guess I would to if I had the $$ but way too broke spending $150.00 a week on fuel ..

Bladestrikes, thats fine for people getting 8-10 min flight times, if that were the case then nitro helis really would die off!

bkervaski, where can you get 6s JST male to female balance lead extensions?

EP Buddy makes them, tho they're currently out of stock on the 6S for some reason:

http://epbuddy.com/index.php?main_p...products_id=127

I use balancing/charging leads from EP buddy and have one of their parallel charging boards too. It's superb quality stuff and EP Buddy themselves deliver promptly....

TP sells theirs packaged in various lengths (I got mine from ExperienceRC) but if you can't find any specifically for your batteries they are fairly trivial to build.
