ELEV-8 - Little brass male and female connectors and blue pastic housings useage

I have enough connector parts to make 40 connections.

The 4 ESCs have 5 wires each for a total of 20.

Where are the other 20 used?

Also, do I cut a blue housing in half when making the third ESC motor connection on each ESC?

Do the male and female connectors go into one housing or do the each get their own?

Thanks,

Lawrence

    We include more connectors than are required in case mistakes are made, and they most likely will be!

    On the ESC's, there are three blue ouput wires on one end, and a positive and negative(black and red) input on the other end. The positive and negative leads from each ESC will be tied together to go to the positive and negative connections of the battery. The blue output wires will be individually connected to a lead on the motor (one blue lead per lead from the motor). I would not recommend cutting any connectors to make a three socket connector!

    The Male and Female blue housings and brass connectors typically are paired in the following manner:
    Blue Female Housing
    > Male Brass Connector
    Blue Male Housing
    > Female Brass Connector

    Let me know if this helps and if you

    Okay, I guess I understand everything - almost.

    Once the motor is wired and powered isn't their a chance that you will have to switch the wires around to get the correct rotation?

    This would be harder to do if you have to take the connectors off and on the housings.

    I still don't see how you hook up three wires to two-pole housings. You would either end up with one "out of housing" wire or one unused housing pole.

    Thank for your help,

    The blue housings are only intended to be used on the battery connection ends. For the ESC to motor connections, you will only want to use the bullet connectors themselves, as you will most likely have to do some wire swapping to get the correct motor rotation. I like to keep everything the same on mine and, and I use male connectors on my ESC's, and female on the leads from the motors.

    I think this is the norm. I'm pretty sure I've purchased either ESCs or motors that came with connectors pre-installed and they had the male connectors on the ESC and female connectors on the motor.

    Is Parallax still sending XT60 connectors with the ELEV-8? I thought my kit came with some.

    Since I have so many batteries with Dean's connectors, I'm sticking with those (or the HobbyKing version) for battery to ESC connections. I've gotten used to Dean's and some of the XT60 connectors I've tried where really hard to get apart (I'm not sure, but I didn't think the connectors I tried were fakes).

    When you put your heatshrink tubbing on the ESC to motor connections make sure and use heatshrink all the way to the end of the female connector to avoid possible shorts.

    I know I've mentioned this several times on the forum but once again I'll mention how much I like clear heatshrink tubing. It's really nice to be able to inspect the solder joint through the heatshrink. NASA is also a fan of clear heatshrink tubing.

    Isn't that backwards? The ESC is the power source in the ESC-Motor connection, so it should have the female connectors to prevent a short if they come loose.

    And yes, I know with a quad that you probably have bigger concerns with a loose ESC connection, but it's the principle (and in a plane you would care more).

    I wondered the same thing.

    One of my guesses for why it's done this way is to prevent the motors being directly connected to the batteries.
