| BEC to Servo connector
Not sure if anybody else has posted this but this is the first I have seen of these. For those of you that freakin hate trying to crimp those tiny ends on this is a good fix. You can find the connectors here http://www.pololu.com/catalog/product/1065 thanks to my friend Moes670 for this link. And thanks to Jim Baddmann for getting me started on finding these things. He already had some but didn't know where to get them from. Although the ones I have I found at the local electronics shop. These things fit great. In the pics I am missing the bec on the other end but I think you get the idea. Last edited by Diamond D; 01-04-2011 at 10:08 PM. |

But the servo still needs signal from the rx! Only the red and black wires can go to the bec the yellow has to go to the rx! But still sweet none the less! |

Let's see a completed pic with how your wiring the BEC wires. Do you plan on splicing in another servo connector (signal wire only) and some shrink tube to plug it in to the ESC? |

| Yes you will still need to pull the signal wire out and go the the RX and you will need another plug. You can also break these down to two plug ends. These are breakaway connectors.

This is a great idea Dave. I've been using tiny 2mm bullet connectors to wire in my BEC's, another option that isn't hardwired so it can be replaced quickly at a comp. |

Here is another way to do this. Bust off three pin section of these pins and put a Z bend in the signal pin going to the bec. The pin will now ride above the BEC connector. Solder on a lenght of wire to reach your reciever and cover with a bit of heat shrink. One problem wouild be trusting it to stay connected but a lenght of heat shrink or some elecrtical tape would fix that. Plus still easyish to unplug for repair or troubleshooting. Should work well for a clean install and not add to much bulk. I like how all the connectors are inline and take up little space. Should not add much weight at all either. Not that that matters on my 8Lb shafty. But some of those MOA guys in our club are like women always worried about their weight Servo on the right BEC on the left. White wire is your signal going to your reciever. Shows the bend you will have to make. A small pair of neddle nose does the job nicley. These pins I have there was no problem bending the pin without breaking. Untill we get some of the pins in the link I am not sure if they will take a Z bend as well. My guess would be yes but time will tell. Y-harness does the job too...... It is all personal preference. |

I just ordered mine from RC planet ParkZone Servo Y-Harness: (PKZ1063) EDIT: the wires on this harness are so thin its ridiculous. DO NOT ORDER Last edited by dstrbd1; 01-08-2011 at 10:21 PM. |

This is a sweet tech thread! Great job HeavyD (and everyone else that provided pictures) Threads like this are priceless. Only tech I can add is that most everyone has a crappy servo laying around (perhaps the one they're trying to replace) to use for the signal wire's connector. This should be linked into a sticky. |

Good point Krakker I kinda left left that part out. If you don't have a junk servo laying around the same website has the servo connectors and pre-crimped pins with wire. Just about any color you can think of as well. http://www.pololu.com/catalog/product/1902 Save even more wieght..ok maybe not Single wides http://www.pololu.com/catalog/product/1900 Wires http://www.pololu.com/catalog/category/72 White 6 inch http://www.pololu.com/catalog/product/1819 They have longer lenghts as well. |

Something brought up in another thread was to shorten the bec pigtail nice and tiny and direct wire the servo power wires right to the bec on top of the pig tail wires. That way the connector isn't holding back any power and you can still easily program it. I believe the connectors are only rated for 7 amps. Just another option.

Due to clerical error with their system, I got an email saying that they couldn't process my order even tho they got the money, they are not sure how to refund it or from where. I sent the email to my CC company and filed a NO PAY on that charge. They'll get it reversed. Anyway, I couldn't wait so I went ahead and just used a small paper clip for now. (like 53Willy's had done) I put a piece of shrink tube over the connections for a nice clean look. I think my next step is to shorten the BEC pigtail. I had discussed in another thread about direct soldering the power wires for the servo on top of the BEC's board as well, but I think I'll hold off on that. I want to be able to change things out quickly if the need to replace something comes up. Here's my setup. FYI: Thanks to EeePee, this is now in the sticky for BEC installs that JohnRobHolmes has. Nice work D. Last edited by Krakker; 01-11-2011 at 04:47 PM. |

I do similar to the connectors at the beginning of this thread...but. I get gold plated right angle headers. -The gold helps prevent corrosion if the connector gets damp. -If you carefully bend the 90* angle, you get extra long pins on each end of the connector. This makes it a bit more robust. A wrap of electrical tape holds it all together. No cutting needed, makes it easy to swap servos or program BEC's. |
