    I finally managed to register to this forum, and my original plan was to do a build thread of the Digger here, but due to registration issues I had to post my progress to scale4x4 forum, and some of you might already know this build from there. But from now on, I'm going to keep this thread updated alongside with the scale4x4 thread:)

    A quick catch-up for you who haven't seen the Digger before. It's based on Kyosho Mad Force drive line and Savage shocks. Rest is more or less scratch built or taken from various other models.

    Here's how it started by printing a photo of 1:1 Digger down to scale I was aiming at, and tube bending and brazing has also begun.

    With more tube added.

    Test fit of the body. Mock-up engine also in it's place. Yes, this ain't no electric truck. Nitro all the way baby!;)
    [​IMG]

    The chassis almost complete.

    And here she is, finally on her axles.

    Finished and sandblasted chassis waiting to get some green powder on it.

    After coating.

    With the body on.

    Starting to look like something...

    And this is how it looks like today.:cool Still a lot of work to be done before this thing moves!

    I have the front steering system currently in the making, but the progress is kinda slow these days, so be patient with this one!:)

    Looks good so far. Are you going to use beefier links?

    Thank you guys!:)

    Naturally, those are just M3 threaded rod. I have some very strong special aluminum bar that has almost same bending stiffness as steel, and that's what I'm planning on making the links from:)

    Looks great! The digger frames really set themselves apart from the rest being green. Nice build man! Thanks for bringing it onto RCMT!

    Finally an major update!:cool

    I got my secret steering system done! Or at least it's working now. Still needs a lot of testing and adjusting done to it, but it's gonna work nicely!

    Here's a little video I shot of the first steering test. Yeah, it's a wire steering! Bet you haven't seen one before:D

    Thanks man!:cool

    Today I did some tire shaving and Dremeled some grooves to mimic the tire groover marks found in the real monster truck tires.

    And a little Dremel action video!:D

    Actually, this was my first and only attempt at making a tube chassis, so I can't say I build those very often!:D

    Your work makes you look like a seasoned pro! very nice!

    I'm curious about the steering. have you got a chance to try it yet?
