    My Landjump rebuild project...

    This is what I started with. It's been sitting in ziploc bags for over a year. I'm ready to start working on it now. I will take pictures of the process along the way.

    My goal is not factory restoration. I will change parts, and make new ones If I need to. I enjoy this, so it will take time...

    The first thing I am going to do is remove the casting marks on all the suspension arms. I think they are an eye sore.

    The tools I'm using. 2 arms done. Still going to need final sanding to clean up the scratch marks. And a good polish.

    Desperately wanted one of these as a child

    I picked up a small Kyosho catalogue at our local model shop, and must've worn it out willing the picture to come to life!

    I remember the first time I seen a landjump. I thought that thing must go through anything. RC has come a long way since then.

    Well today I decided that I did not like the arms that hold the rear shock. They were really thin compared to the rest of the landjump.

    I had some thicker aluminum laying around and traced them out, and cut them.

    One on the left is the new one. Right one is the original.

    Other thing I did today was cleaned up the left and right arms.

    See that piece sticking up? That's the bracket that hold the exhaust up. It looks like they just stuck a square piece up, drilled two holes and said good enough.

    That's the next part I wanted to change. The first thing I did was grind the bottom surface to match the angle behind it on the bottom. Then I dressed it up a little and it turned out like this:

    Like this look a lot better. And I got to try out my mini milling machine in the process. (craiglist find) Don't know what part I will work on next.

    This is how the front end turned out. I added aluminum tubing between the axles. I milled slots in each piece. Then I put some colored film inside around the axle itself. Turned out pretty good.
    I also got rid of the little piece that held the steering assembly. Replaced with a new piece that spans to both sides.

    Kind of thinking I might make a new servo box out of blue acrylic. If anyone else has some cool ideas, please share.

    I have a new one still in the original box with many extra soup up parts from Japan.

    Thank you so much! I did not know they had a sway bar kit. That's really neat. Would like to see your radiator project when your finished. Did you buy it new and never put it together? Or, are you a collector?

    I bought it new back in the eighties. I also have the Circuit 20 buggy.
