Default 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.



That's it for today.

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.



Here is another picture to show the size difference.



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.



Good enough for today. Getting tired of sanding things.

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.

You got any pictures of it? What kind of hop-up parts did they make for it?

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?

Started working on the landjump again. Got the front bumper made. Also got the fuel tank holders done.

Hoping to have the servo box made in the next month. Might try making the servo save out of aluminum down the line.
(side note, just got done building the Optima!)
