trex 550 with deans connectors????
Wondering if the ultra deans connectors will pass enough current for the 550 to fly at its maximum. I have a new 550 and just received 4 Gens Ace 5300's from hobbypartz.com who are all out of stock on compatible connectors. Wondering if I can use deans connectors from my local hobby store for battery connection. I see these are rated for 50A and the Gens Ace connectors are rated at 90A.

Anybody flying the 5500mah packs on ultra deans? Love to hear.
thanks

Trex 550
I have the 5300mah 6s 35c in my 550trex . Not having any problems at all with set up. When I solder mine deans on I first solder a brass tube on the deans. An then I solder the wire into the brass tube. It works for me. My setup on my 550 switch 1 87% switch 2 100%. been doing mild 3d for over a year with good results. Hope this helps..

I started out with Deans on my 550, and although I didn't encounter problems, the Deans just didn't seem right for this size heli running on 6S drawing the Amps that it's capable of doing which varies with flying capabilities and style.

The Deans just don't look right on the end of the 8awg or 10awg wires. The actual current rating of the Deans is a hotly debated topic - they don't appear to be suitably rated for the 550 running on 6S.

I went with the EC5's - their current rating is suited, and they are far easier and safer to solder onto the ends of the heavy battery leads. They are also easier to grip when connecting and disconnecting.

Expecting that the above will be flamed by those using the Deans on this heli.

Deans work well for me, but for my safety switch to ec5 from 5s to 6s packs.

Dean connectors
For the size of battery that you are running, switch to the EC5 connectors and do yourself a favor. They work better and are much easier to solder

It depends on how much power you're drawing. If you have data logging, check your current draw, both average and peaks. Also, check the voltage ripple, damage to the ESC can be done if it peaks too high.

jojo, i use them on my 550s, and they work fine, but i really don't like them for the larger packs, as was said. I will be switching to EC 3.5s shortly, which are rated to 80 amps. certainly if you want to play and that's what you have they are fine.

I would only use EC5 connectors on this helicopter...
More then one person has had there ESC burn up using Deans I have read.... I wouldn't use EC3.5 way to small ...

Deans are fine on a 550. They are a pain in the ass for sure soldering to that size wire though.

I am in the process of switching all my big stuff to Anderson Powerpoles and love them so far. I planned on keeping Deans for my 3s stuff but I like getting the use out of my new crimping tool, so looks like everything will be Powerpoles....

BTW you can probably crimp ends on 6 sets of batt's using the Tri- crimp tool in the amount of time it takes to solder one

Thanks Mx!
Very cool video... I did go with Ec5's on my 550. I appreciate everyone's advice on here. It really pointed me in the right direction. I would have loved to see Ec5 connectors in that test. I am most impressed in the Deans connectors though. Seems they lasted until the solder melted. I got kinda tired of the Deans connectors on my 450. Not going to change them.... The Ec5s are kinda tight like the deans but no biggie. Love the Ec5's but I'm up to a good $40 to outfit my 7 packs and chargers....

I betcha if you/he used silver solder on the Deans they would have held quite a bit longer. Using some soft (lot's of lead and low tin content) copper pipe solder is why the solder joint failed. I'm not in the 300 amp club on any of my helicopters so I'll stick to the old tried and true Deans. A crimped connector will always out last a soldered one when resistance goes up and turns the wire into a fuse able link....

Deans create resistance under higher amp loads which the 550 6S helis can create. Resistance creates Voltage Ripple. VR is probably the largest contributing factor to ESC failure...ALL BRANDS.

What evidence do you have that supports that claim?

I call BS.....I'm totally OK with people passionate about another brand or style of connector but to stuff a load of horse crap down others throats is just plain pathetic. You trying out for a role on Pretty little liars?

flew deans for a year on a 550 pulling 240amps/5300 watts.

never a problem. have always used deans. they will work, no problem.

Wow, that was weird.

There is a lot of evidence on the forums about deans being a low amp connector. Most online stores that sell them and rate them will not claim more than 60~70A continuous. For high power applications that is low, and although people "get away with it" it is not the best way to go. I watched a pilot discharge a 5000 6S on a 550 flying very hard in less than 3.5 mins. That's how fast Tim Jones discharges the "Beast". He's on 12S, but the Amp draw was the same on the 550. Would you want that high amp discharge going through deans? High VR happens mostly during spool up, at least on bigger helis, but large connectors (6mm or bigger bullets) will really decrease that. I went from deans to EC5's to PRC 6's(which happen to be the largest sheathed bullets available but very compact) in mime and others testing of VR and talking to EE techs in the know. Please, don't try to "get away with" using the smallest, weakest, connectors and wire you can in high power applications because all it will do is create problems, either short term or long term. If on the other hand the application is low power, use a lower power connector. In other words use the right connector for the right job, and in R/C helis, up to a point, bigger is better, esp. in terms of line resistance and keeping very damaging VR to an absolute minimum.
