Hey scale racers and modifiers,
I was stoked as to get my hands on a Nissan Proto Z and set to work on making it a quick gravity racer. To my surprise when I drilled it apart, the rear stem is plastic and attached to the window/top shell of the casting!
That means, it's not as straight forward as the metal stems I'm used to so I'm not sure how to screw it back together.
I have considered filling the plastic stem with glue then adding a thread into that but keen to hear how you have tackled this hurdle, before I go too far with glue on this.
I do want to use screws instead of permanently gluing it shut in case I need to edit the weight for a race in the future.
