Ec5's are rated for 120 amps continuous current. (http://www.horizonhobby.com/products...r-2--EFLAEC502) My datalogs indicate 70 to 90 amps throughout my flights doing sport and light 3d. Another issue with ec3's in this application is the physical size. My 6s 5000 Zippy and Turnigy battery leads will not fit in the connector without trimming off the wire to slim it down, which lowers its capacity. |

I too agree with the EC5's for this machine that frequently breaks the 100 Amp barrier. Just note that not all EC5's are the same, specially with the male connector. I find that the tapered male connectors hold tightly in flight, but are easy to insert and remove. http://www.hobbyking.com/hobbyking/s...idProduct=9194 You can argue that the bullet design pictured below offers more surface area contact and thus better transfer of current. Although I cannot contest the surface area contact claim, I question its practical significance. I can affirm that the tapered design is much easier to insert/remove without forming calluses on my fingers, and there is not decrement in ripple voltage as measure with the Castle logger. http://www.progressiverc.com/ec5-con...s-2-pairs.html Besides, if you can wait average 13-17 total days (at least for East Coast US folks), the Hobby King tapered EC5's are the most economical I could find. |

You want to run EC5's give the current demands of this machine....

I've been running mine on EC3 for over a year with out issues. I fly sport & light to moderate 3D now. I'd say "if you have them use em."

yes, not only because they are better spec. They are bigger to handle and easier to solder, if you buy some packs with AWG10 (or 8 as in my new!) you will have problem with EC3. And... if you buy some bigger HV-machine you will be glad you already have EC5 installed  btw. congrats on your new heli! |

+1 for ec5. I just set them up on my 550 in the last week

EC5s because they are capable of more than 120A continuous current. Dave Sent from my iPhone using iFingers |

| AR90 | Roger that, 3 people is enough to convince me.. Spending an extra $15 to be safe doesn't bother me. | |

I've got a 550 kit showing up today, and I'm going ec5 as well. Sent from my Galaxy Note via Tapatalk |

| CyprusFlyer | If you look back there was a debate about this a while ago, trust me EC5. | |

EC3 or EC5? Finally pulled the trigger on a 550 just a short while ago.. Now I'm wondering if EC3's are capable of supporting a 550. I have a bunch of them laying around from my 450 build and I was hoping they would be usable.. Or am I going to have to switch over to EC5s.. Thanks in advance
