Introduction ~
Our patent-pending construction method is at the heart of what Scale Pursuit Models creates.  We utilize superior materials and integrate them to form a coherent and robust system.  Scale Pursuit Models is introducing two materials, brought together for the first time.

One of these materials is expanded polypropylene (EPP).  Our entire airframe (fuselage, wings and empennage) is EPP!  EPP is well proven as a highly durable material for R/C aircraft and we are the first to bring it to giant scale.  EPP is lightweight yet capable of flexing and returning to its given shape.  Squeeze it, punch it and you will not dent it.  This is no flimsy styrofoam model!

Although EPP makes for a rugged airframe it is necessary to cover it to bring the model’s appearance up to par.  Traditionally, this has been accomplished with iron-on materials but we use something much better. 

The second main component of our construction method introduces a new means to cover the EPP bringing the model’s appearance well above par!  We mold highly detailed polycarbonate skins that systematically cover the entire airframe.  These vacuum formed skins get adhered individually to the foam in an overlapping fashion thus preventing any likelihood of the skin delaminating in the air stream (much like the process that aluminum skins are applied in full-sized aircraft).  Molded into the skins are rivet, panel lines, and hatch details.  As an additional benefit, once these skins are adhered to the EPP they naturally take on the appearance of a riveted, stressed-skin aircraft with its non-uniform surface undulations.  This scale effect is rarely replicated on model airplanes.

Together, the EPP and polycarbonate skin create a model with perhaps the industry’s most durable airframe while delivering an incredibly realistic appearance. But durability is more than having a tough airframe. The ease of repair is also an important element of our construction method. To learn more about how to repair a broken model, click here.

OK, now you know what materials we use and their benefits to modelers.  So what’s left to do to complete the assembly process?

Construction Overview~

Before the skins are attached, the EPP airframe needs to have some wood reinforcements, such as spars, firewall and retract, wing and tail attachment points.  These wood structures get glued into the EPP to provide the needed airframe rigidity.  Next, radio gear, retracts and engine can be installed and fitted.  The fiberglass cowl can then be cut and positioned in place.  Once these components are installed the skins can be applied.  To learn more about how the skins are applied, click here.

Once the airframe is covered with skins you can begin to create scale details if desired.  These details might include functional gear doors, cowl hatches, cockpits, navigation lights, etc.

Our quick-build kits get you to this fun, detailing stage fast.  Next, you prep the skins for paint which involves a quick buff job with a Scotch Brite pad.  No laborious sanding needed!

Well, that’s the construction method in a nutshell.  Nothing real complicated – anybody with ARF experience can handle this assembly process!
