    I've got to say, they all look like dry joints to me, no smooth fillets of solder between the wire and connector solder cups.

    You've probably got one of those budget Maplin "30W" soldering irons. Do yourself a favour and invest in a good 100W Antex, they're ~£17 and will solder all connectors with ease.

    It's a 40w that I got from Amazon.

    I agree with Pinski1. Those soldered joints ain't up to spec.

    For that kind of work I use a cheap 100W Ironside Soldering iron with the thinnest point I could buy for it.
    (for heavier work I have other points, up and including rather heavy copper blocks, electrocoated with nickel)

    I'm tempted to buy the 150W brother of it...

    I also use custom made teflon clamps to keep the connector pairs in a solid lock. (handy if you can make those yourself from billet or sheet)

    Another investment I can advice, heatshrink in the right dimensions. It can hide a lot of sins.
    The alternative is hotglue.

    Those few extra watts seem to have made adifference.

    Sorry if its looks a bit blurred, but myphone didn't want to focus on it.

    Shocking what a "good" iron can do compared to the really awful ones

    The other advantage is that as it warms up the metal bullets much much faster the plastic doesn't get time to properly melt.

    Wiring results for the front motors.



    Seem to have a bit of the same problem as Wyrm did, might use the transmitter upside down.

    Spaghetti Junction.

    Finally done wiring for the drive, tested the linear just to see if I got the wiring right and made the little safety light so I know the robot is live.

    All I need to do now is tape the wires, make some more safety lights, test the weapon a bit more, order some armour and anything else I might have forgot.

    Looks nice and messy :P Seriously though, good work so far.

    Removable links perhaps? I can't see them in the photo.
