Part One: Normal Faces Out

Objects seen in PhoenixRC are made up of points (vertices), lines between points (edges) and planes made from 3 or more edges (faces). An object has a group of faces on the side towards you and a group away from you. An object is "manifold" if the side facing away from you is enclosed fully within the object (considered water tight). Manifold Objects are easy, they have an outside face (normal normals) and an inside face (flip normals) sharing the same vertices and the rendering software can recreate these from logic. In designing our models, we very seldom get to have true Manifold pieces to project our 2 dimensional artwork (texture) onto. We tell the rendering software..."This surface is normal" or "this surface is flipped".

When the Canopy or Portals of our model are just grey texture that we have projected onto it, we don't care about the "see-through" state of the faces behind the texture. But in both Blender and Phoenix builder we are given controls to 1) make the surface (material) transparent by a percent entry and 2) make the face normal or flip. In this mini-how-to I will also show the control entry for "reflective" (mirror in Blender), since it is useful and right next door.

Part Two: Separate a Canopy

This portion deals with Blender techniques, getting this done before exporting the project to OBJ. And I will presume that the fuselage of the Model is roughly...Continue Reading

Harrier AV8B Longflight (5 min 23 sec)

When I found my PhoenixRC 4.0 disc in a box while cleaning, I nearly threw it out. It's a good thing I didn't!

I discovered a whole new world of great members who are still flying PhoenixRC and thriving. I tried downloading a model that I have wanted and broke out an old laptop to demo on. It has been "all aboard" since then.

Part One- Small EDF power for UMX-sized Jet Models.

This Mini-HowTo is intended to describe my work-around for some "wish list" items that I find lacking in PhoenixRC. (There are more, but here's a start) I believe EDF jets were around by the time the original v3.0 was conceived, but were only lightly represented in updates (Habu, Habu2, A10 hand-launched). The only methods available for building your own, in Builder, were A) scale down a turbine or B) use a faux prop, and make a pusher. The creative team hadmore options, but the lonely user had to "trick the sim". I basically used the Habu2 (a scaled-down turbine) and disected it. Importing the .geo (geometry) file into builder with a much smaller preset wingspan, (0.372meters) to match the 30mm EDF powered UMX-Habu-S. I then punched in the position and sizes of the airfoils to match the model in Builder.

Why did I do this? ... Being equipped with a 3D printer and reading the 30mm EDF thread, right here on RCG, I had a bunch of beatifully designed ducts and Impellers that I wanted to make visible...Continue Reading
