arent those the ones you have on the Diabolo where you said there is a chance to short them if you dont pay enough attention?

[George J]

The Supra connectors look really good but I don't for one moment believe you can have a 'faulty' EC5 and it can only be the way its soldered together if you have one come apart and it certainly isn't because of heat build up imo! I'm completely open to hear a proper explanation, and really hope someone does explain it, for an EC5 cup being at fault here and not the soldering itself?

As for the possibility that you can have an EC5 fail depending on what ESC you use is complete nonsense!

Yes you do have to pay attention to what your doing , and you can short them which is the only downside. Plugging the first battery into the ESC when loading is the way to use these on either 10s / 12s or 14s setup etc

Ive never had a EC5 fail as yet and im always puzzled why this happens as I hear a lot of people having this problem and I have also seen it at the field !

[Raving Jim]

I've always used a burning flame so it's like a molten pool when soldering them,Never managed to have one desolder on any 12s setup but I did put savox hv servos in my logo 550 a while back all running off the yge 90lv esc Bec an obviously was drawing way too many amps, two flights running on vertical tick tocks the esc de soldered on the ec5, solder flicked all across the frames , backup guard saved it , swopped the servos out an never had a problem , ec5,s are certainly up to the job an I've only ever seen a couple fail on other people's models due to a cold soldered joint .

[Peper]

If the EC5's were so good people wouldn't change to Castle and/or supra,

there are better designed connectors out there, why sticking with the mediocre?

we will have hundreds if not thousands swearing by the EC5's, so did I, until I started pulling some amps from my 700's and having them fail on 3 occasions.
since I changed I didn't have any issues and I am confident neither will have Phil when he installs the Supra connectors.

call me a bad solderer, tell me my soldering iron is not up for the job (use gas torch by the way), direct me to youtube videos showing me on how to solder EC5's... but please do yourself a favor and re-visit this thread if you get "cold solder joints" in the future.

[George J]

I agree completely that there are better connectors than EC5's Bruno but that does not explain EC5 joint failure which is what I'd like to get to the bottom of. It's easy to blame the connector when in fact it's not a perfect soldered connection.

If I do ever have an EC5 fail I'll 100% blame nothing other than my soldering!

I've managed to connect them wrong on 2 occasions, makes for an interesting spark and melt down when you connect 2 6s packs together.

[waveydavey]

I think you've hit the nail on the head again. The point is the connectors are rated way below what you're expecting them to allow, the result is resistance and with that you get heat. A couple of hundred degrees is mental and you must notice this when disconnecting the connectors though, or when they desolder in mid air

[George J]

Never have I ever felt enough heat anywhere on a heli to de solder an EC5 or any other connector for that matter and if there was then you probably have bigger issues on the heli!

I guess this subject will just go round with no agreement and no one likes to admit that it's down to them when something goes wrong.

[GIXERMAN]

Yep George, looks like winters here.

Indeed mate.

[GIXERMAN]

Indeed mate.

i think pretty much everyone at the weekend was on 5mm apart from me and bruno. and there was a few models getting a hard time! at white horse

[Peper]

If it was down to me, surely i would be getting the same problem regardless of the connector? I use the same gear to solder and the same setups on my helis and only flying harder...couple of hundred flights later, no issues with unsoldered connectors.
