Admittedly going to be a long while until I get into this one, still working out exactly what I want to do with it.
For those that may not be familiar with the RPM 91 Worlds parts

That's a nice canvas to work with. I'd start by dying all of the nylon and towers black.

Nice! That’s a unicorn buggy. A lot parts from different manufacturers has to come together.

Thank you gentlemen, I’m definitely doing some careful planning. Make sure I do it justice.

Did a quick brush off just to inspect everything, found a couple nice pieces and some I need to question.
After making the front springs go away for good I can see the front rpm cups, eyelets, spring retainers, and adjustment clips are present.
Couple other rpm goodies.
The rear bulkhead has been cut out and sits down around the lower chassis, Is this normal ?
Also I’ve decided I like the rpm parts in blue, pretty even dye job and in good shape so they will stay this way.

The purple and pink definitely gives it that 80s/90s look and feel when neon/fluorescent colors were popular.

Those yellow front springs are correct for the rpm front end. They are the 'medium' set from rpm and what they recommended for initial setup.

Oh really, I honestly thought they were Losi springs.

If they fit the rpm collars they are rpm. I think crazy enough you can still buy them from rpm.

Yeah, they had yellow (soft) and silver (medium).

Yes they did fit them well. I mean it’s not that I threw them out I just really don’t want yellow springs on it.

As for the turnbuckles, Tecnacraft ?
Think they are long enough that I can ditch the Losi ballcups for more appropriate RPM ballcups ?
The Losi cups use the same ball size correct ?

Yes, same ball size.
And RPM cups are made in two different lengths.
There are some comparisons here.

They may not be perfect specimens but since I know it’s been mentioned before and it is something of a rare opportunity to do so, I figured I’d take some side by side photos to display their similarities and differences shape wise.
