Losi Jrx -JJJ

Post by Johanp »

So, what do you do when you´ve torn down two complete Jrx-chassis cars to get the best parts into a -91 worlds replica and is left with a lot of parts. You also have a box full of new parts.

On top of that, you´ve got an unused carbon “hybrid” chassis from the GP3D -91 words kit laying around. You also find the Factory Works front brace you got a long time ago.

And you´ve always been fascinated by the looks of Jumping Jack Johnsons prototype car from 1989 ROAR nationals.

Of cause you warm up the computer, design some bits and start 3D printing.

I don't think i've seen this prototype before but I like what I see.
Consistency is the key I keep misplacing.

This is not going to be a direct replica. More inspiration taken from the looks of Jacks car.
The carbon chassis has Pro SE shape and I´m using the exising holes, so the central support is very different from the original.
Currently the ladder type sides are 3D printed, but they might get cut in carbon (without the bracing) for the finished car.
Let´s see where we end up with this one. :)
