JRX2 - The project.
Hi,
After a more than 20 year break from RC I got hooked again a while ago. While cleaning at my fathers place,
I found my old stuff. An original HotShot, an Optima Mid, a Schumacher touring car and my last competition Losi XX Cr.
It took me a while to go through and restore some of them.
I then realised that I wanted to get a JRX2. It was the car that I won my first regional race with.
There were not many of these raced in Sweden at the time (mostly Schumacher and RC10) and even knowing roughly
where to my old JRX2 was sold, I could not find one.
So on to Ebay then...and eventually there was a rough one that I placed a bid on and I won it!
Shipping, taxes and fees for shipping and importing it to Sweden was double what I paid for the car. Oh well...
The car needs some love. I don´t know, but my guess is they used it to jump over kerbs because of the severely damaged front.
It had a Junior 2 front shock tower, reversed front arms with drilled out holes for mounting the shocks. And H-arm conversion.
In the box was a lot of stuff. Extra shocks, shock towers for Pro and Pro SE, extra gearbox, front arms, bulkheads, 5-link suspension,
steering parts, Junior 2 chassis and a Novak Dually ESC.
Going through it all, there were not only a Jrx2 but also almost all parts for a Junior 2.
I started to disassemble the car. I cleaned and sorted all the parts.
Then I started the search for missing parts. Most are ordered, but I had to 3D-print some because I could not find them or the prices were "wrong"...
The chassis needed some serious help. It was badly damaged in the front, delaminated and completely missing a corner.
After a good clean of the damage I used super glue to fix the delamination.
I then made a mould/fixture to help shape the front corner.
Then mixing epoxy and filed down carbon fiber dust that I poured into the mould.
After a week of curing I removed the mould and using finer and finer sandpaper I reshaped the chassis.
After some final wetsanding I applied black wrapping to hide the worst scratches. It turned out ok considering where I started from.
And here I am at the moment, everything cleaned and sorted, waiting for the missing parts to arrive so I can start the reassembly.

Re: JRX2 - The project.
Amazing work on that chassis! When I saw that first picture, I thought it was dead. But you saved it. Nicely done.
Hope you're doin' something fun.

Re: JRX2 - The project.
Very inspiring work on the chassis!
Just like TRX-1-3 said, after I saw that first picture, I figured it was toast.
I am really looking forward to seeing the rest of your work. Thanks for posting.

Re: JRX2 - The project.
I always love seeing someone repair something like that rather that just throwing money at it. I have massive respect for the skill and craftsmanship involved in that repair, nice work! I thought it was a goner. Are you planning on using a shorty bumper of some sort to protect it?

Re: JRX2 - The project.
Thanks for your comments!
The goal is a running car when I'm done. Judging by the state of some of my parts it is never going to be in mint condition.
The repair on the chassis is never going to be as strong as the original chassis. But I think it will be strong enough to take the car for a spin when it is ready.
I do actually have a bumper, the one that attaches under the chassis. I'll at least use it when driving.
I'm not in a hurry to finish. What I have shown so far has been done since the car arrived mid December.
I'll keep you updated.

Re: JRX2 - The project.
I have a question for you:
Why are the top shaft different between the two gearboxes?
Design change from Losi or aftermarket?

Re: JRX2 - The project.
The brass gear wore out quickly, it was a running change by losi
It's time to stand up to the bully. Support the companies that support the industry, not the ones that tear it down. Say no to Traxxas

Re: JRX2 - The project.
Talked to Gil about this a few years ago. The actual issue was consistency of product. The brass gear didn't always get pressed on the to the shaft at the factory centered correctly. So they had quality control issues that they had to stay on top of.

Re: JRX2 - The project.
So, first package has found it's way over the Atlantic.
I also realized that I was short on good screws.
So I sanded the heads and painted them black. Good to have as a backup.
Mostly small stuff, but also some for a future project. I also realized that I was short on good screws.
