Would the lift be offset by the Drag penalty ...? Sure a great way to strengthen the fuselage nose...but then ,it's more of a Doubler...and may create a stress riser if ended abruptly..??? Hmmmm???? What about an angled or even curved ending (TE)of the fuse KF strip ... flowing into the fuselage lines???? Experimenting with LAR KF ,these issues arise frequently ...Really Nice plane Kaos...!!!

When you guys buy your spruce , make sure the grain runs straight from one end to the other..grain feathering /slash grain running out is practically worthless for a spar ...read the wood !!! We always buy our wood at the LHS so we can see/select the good stuff and eliminate the junk...otherwise a bad spar wood is just weak dead weight ... FYI...

Excellent point, GPW. I look at several pieces sometimes before I select one to purchase. If there seems to be a lot of good spar stock in a batch, I pick up several to have on hand. In addition to what GPW suggested, I'd also add that the tighter the grain (more lines) the stronger the spar will be, so I select based upon the direction the grain is running and the grain density.

GPW, thanks for your kind words about the plane.

As far as my experimental version of the Regal goes, you can see by the attached picture that the plane I created has the step designed into the fuselage foam. Since it's not really a doubler, I doubt that my design would be any stronger than any other plane. The theory being tested here is to see if a vortex of air will form behind the step in the fuselage with the normal airstream passing by virtually frictionless, and thus reducing drag. Then there's the whole "lift thing" when flying knife edge. We'll see.

If I've misunderstood your post, please clarify.

Spruce huh. Well, I already glued the arrow in, so hopefully it won't be too heavy. I don't know how it would compare to the weight of a spruce spar.

EDIT: Just weighed the wing without ailerons, and it's 3.25oz, hope that isn't too heavy.

You guys need to weigh everything you put it on a plane , just so you'll know what's heavy and what's not ...

I doubt that the weight will be an issue since the Regal has a lot of wing area. If you want to compare the weight of your arrow shaft vs. the spruce, one of my 1/8" X 3/8" X 36" spars weighs .5 oz. The reason for the 3/8 dimension was to get a step that was nearly 5/8" above the top side of the wing bottom sheet.

Finally, Regal Paint

I finally got my Regal painted. I like to keep my leading edges of the wing a light color so the wing doesn't vanish from view when I drop below the tree line flying low. I also like a paint scheme that shows up well in flight, and that provides a significant difference between the upright and inverted appearance. Oh, and I like to keep it simple! I think this color scheme satisfies my rules.

I paint all of my foam planes with common water based acrylic paint that's available at most craft stores. It can be thinned and shot on with an airbrush or applied with a paintbrush. This particular job was applied using masking tape and a paintbrush.

Terrific paint job.

Hey, Ralph Lauren, step aside. Kaos2 is coming through. I can't wait to see that plane in the air doing its thing with those sharp graphics.

Nice paint job. She looks great. Of course, if you'd painted it red it would fly faster.
