    I don't know what the M8 stands for, but I think I've seen that crane before.

    Not sure what you meant by M8, but this is undoubtably going to be a great build!
    Are you reffering to the Swiss Sauer M8? Or a military 8x8 like the one pictured above?

    I'd love to see how this turns out, good luck!

    Well, here is the second part...

    The detail is amazing. I am even more amazed it arrived in great condition, it was sent in a plastic bag, with not protection at all.

    Man, I was Traxxas sold the TRX6 as a kit, with no body or electronics...

    Oh well, I have abused my TRX6 body, and will need replacing soon.

    I think I've seen that cab before

    A TRX-6 kit would be nice.

    Finally got caught up on my school work, and carved out a little bit of time to work on this project.

    First, I ripped apart an old servo and turned it into an ESC. It works great, the next step is figuring out the resistance balace between the two directions so I can replace the pot with resistors. I think it is 2.5kohm on each side, but I need to play with it to find out.

    Next, I used the ESC to figure out what channels are what on this thing, thankfully, after the multi-ESC circuit, the wiring is straight forward. I was a bit surprised, the wiring going into a slip-ring, so I do not have to limit rotation at all.
    If you are interest, here are the colors:
    Blue/Yellow: Winch
    Purple/Green: Boom in/out
    Black/Red: Back lift (single)
    White/Orange: Front Lift (dual)

    The little board on the base is a 5 ch ESC, that gets power and signal through what looks like a standard 3-conductor servo connector. Given that I have no plans of buying the radio needed to run this guy, it will find its way into a landfill via my trashcan; after removing the servo lead, of course.

    At a tipping point between deciding if I am going to rip apart five servos for their controllers (will use the rest of the servo as a servo winch), or just get five HW1060s. Given that this thing runs off of 30awg wire, I am leaning towards the servo controllers.

    The first speed control is built and tested, four more to go. I also have to design cases for them... fun stuff!!!!

    I am making slow, but steady progress on this.

    I have four of the five ESCs wired and installed, #5 should come in sometime around the end of the week. These are all getting wired up to a DX6e six channel RX, and will be powered off of a CC 2.0 BEC fed off the main battery.

    I designed and printed the ESC tree and stand, a cover that looks like a GENSET will go over the top of it. The GENSET has working doors that line up with the pots for easy access for adjustment!

    In case you are wondering...

    P = Pedestal (the base at the bottom)
    W = Winch
    B = Boom (extend/retract)
    RS = Raise Single
    RD = Raise Double
