Use solder on the soldering iron and let it run to wires. Make sure both wires ( or metal part of the XT60 connector) are fairly hot. Soldering should be done in 10 - 15 sec provided soldering iron and wires are nicely warm.

As to temperature setting, you do not want it too hot or too cold. Temperature should be high enough to melt the solder in 2-3 sec.

Hope this helps.

Cheers
Thanks for the useful info & video link.

So even if you use solder that has flux in it - it is useful to use some separate flux as well? I have got a flux pen would that work?

As the XT60 socket on the old Phantom charger has a broken lead as well I can practice on that. I have done a few solders/unsolders. And pulling hard on them I can see that if they break it will be the wires not the solder joint which I guess is good. Though the join itself does not look anything like as clean on the ones shown on videos. But not that much worse than the original DJI one!

Still to practice using heat shrink tubing. Will try with the heat from the iron first.
Will still be more fiddly doing the actual socket on the Phantom itself. Although if I do decide to crack open the case will give me an opportunity to give the Phantom its yearly MOT as it were! And also an excuse to do a better join on my aux power cable for my gimbal. I was amazed when my earlier solder attempt actually worked! But prior to the earth lead finally giving way on the Phantom my Aeroxcraft has been recalibrating itself as if it is briefly losing power to it.
Not sure if its the earth connection issue, my aux lead connection now giving way or the jst plug/socket.

cheers

so - what can you recover? is it a complete write off?
Hey, same thing happened to me a couple weeks ago. She fell into a clear water creek like the one on your video. I rescued it, separated the shells when I got home and let it dry out naturally for a few days and she flies like new.
My poor Mobius Action camera didn't fair so well, I ordered a new one.

Hi Dave,
I managed to remove the pins from the male & female connectors today. And to my eyes look fine and the wires crimped into them are intact. And yet when you connected up to the battery with the Phantom & gimbal powered up if you wiggle the connection to the the gimbal, it reboots itself. And for the first time today if you really wiggle the connections the leds on the gimbal board briefly go out as well. So it must be a bad connection but just cannot pin it fully down and cure it so far!

Seems like if it is resetting itself, it must be shorting out then robooting.
Very strange..

I'm not sure what you mean by "Otherwise you could be asking a third party to take unnecessary risks" ..

What risks are you referring to ?

Russ
Hi Russ,

a. risk of damaging the lipo
b. risk of shortening the life of a lipo and finally
c. risk of a runaway reaction i.e. fire

Filmscum already had a fire when charging a lipo.

I'm sure you know too that you just cannot make a blanket recommendation without knowing the brand of charger or lipo, C rating, capacity etc etc.
IMO, Play safe - it's not worth the risk.

Cheers

Hi Bill,
Flux in a soldering wire is only a small amount and is never enough. Best to use some extra flux. But remember to keep the wire clean and remove any grey dry solders with a small file or sandpaper.
Trust me, the more you practice the better you get at soldering.

Cheers

There is no problem what-so-ever of charging packs at 1C .. C being the designated Current discharge rate of the pack .. i.e. 2,000 MaH = 2 Amps, 5,000 MaH = 5 amps, etc. Charging these two examples at 1C would therefor mean charging at 2 Amps and 5 Amps respectively. There is also no problem with charging at 2C .. meaning in this case 4 Amps and 10 Amps respectively, as long as the battery manufacturer is in agreement. MaxAmps claims many of their packs can be charged as high as 20C .. I think that is insanity !! Here is the link .. it's good reading ..

You are not telling me what it is that "is a blanket recommendation" that may cause ..

"a. risk of damaging the lipo
b. risk of shortening the life of a lipo and finally
c. risk of a runaway reaction i.e. fire"

The closest thing I can see is that I said that could cause the above risks is .. "There is also no problem with charging at 2C" .. I also included .. "as long as the battery manufacturer is in agreement".

Is this what you are referring to, or is it something else ??

Can of worms. Sorry guys. All I know is I never charge over 1c. Never Ever. Could have been my charger or a batt that suddenly went haywire despite being balanced and never pushed beyond limits.

I just wanted to warn anyone who walked away from a charging LIPO in their house to not do that. I did it 1 too many times. I'm still trying to wrap my brain around the whole charging thing which is a bit daunting.

In the eternal words of Rodney King, "Can't we all just get along"??

Hey, Film:

I think I recollect you were using a Turnigy charger ??

If that is incorrect, please let me know ..

Also, what brand battery pack lit up on you ??

hear we go!!!!!!!!!!!!!!!!!!

http://www.dailymail.co.uk/wires/pa/...se-drones.html

why do they always show a Phantom, I've got 5 other MCs and they look nothing like a Phantom!!

different makes of lipos..............
with the standard camera mount and my hoyrzon HD camera on board I can get 10 minutes flying time with the Phantom lipo.
I bought 2 Zippy 2200mAH 25c lipos and only get 8 minutes.
now I've just got 2 more, Turnigy 2200 mAH 20-30c and with them I'm now also getting 10 minutes flying time????????????????.
zippy not so good?????

That's okay Teccer from what I understand not only is it illegal to fly a MC in Yosemite National Park but as you enter there is specifically a sign showing a DJI Phantom with the cross across it meaning "no Phantoms" allowed here.
Unfortunately whether we like it or not the DJI Phantom is the most widely recognized UAV MC out there.
I have people stopping me in parks and the like saying "hey that's one of those Phantoms" ,and these are people that are not in the sport.
That also means that we are spokesmen for DJI and for MC's all together every time we fly ours in public.
I filmed an outdoor event last weekend with mine and I had people coming up to me all day long curious about it. And dogs too, the event was called a Mutt Strut and there were over 100 dogs there. You know the fascination that dogs have with flying objects.
It was challenging to keep the craft away from kids, adults and dogs.
