Building

the Porsche 911 GT2 (997)

How to build a custom RC Porsche 911 GT2 (997)?

This is how we did it.

mfactory33.com

A German legend again! Everybody is familiar with the basic curves of the classic 911 shape. This time it’s painted as a Highway Patrol speed enforcement.

As always we let you be the judge to tell how well we could capture it.
Our aim was to get it as much authentic as possible.

We’ve changed the slidable concept for a fixed one, because we realized those kind of U profiles are hard to get.

Here’s a full assembly video of the actual chassis. Enjoy 🙂

Most used tools

Scalpel&Allenkeys&RASPs

Scalpel for removing print support. Keys for screws. Every kind of Rasps to get the surface smooth and even.

Most Used Parts for Assembly

Super glue

Both Gel and Liquid ones. Use GEL when putting parts together. When it holds use LIQUID on the surface.

Super glue for assembly

Glue Gun

It’s adhesive sets very quickly. We used it only inside the body kit, because on the surface leaves nasty traces.
