Duane,

I have been studying the black and whites and I have a couple of questions. First, it appears that the upper red and lower black on the fuselage are parallel to one another. Is that correct? YES, THANKFULLY THE LINES ARE ALL PARALLEL. THAT'S WHY THIS PAINT SCHEME WORKS SO WELL TO DEMONSTRATE WHETHER OR NOT WE GOT IT RIGHT. YOU CAN EASILY SEE WHERE THE DIFFERENT COLOR LINES INTERSECTS CERTAIN LANDMARKS ON THE FUSELAGE.

Second, If the answer to question one is yes, then the top of the dash appears to run parallel to those same lines, which means the bottom of the dash must be angled downward, correct? YES THE DASH IS ANGLED. IF YOU LIKE THE SIZE ON THE PROTOTYPE, I'LL MEASURE IT FOR YOU. I SPACED THE DASH 1/2 TO 3/4" ABOVE THE BLACK STRIPE
Also, some guesstimates of the gaps between the upper red and the top of the dash would be helpful. And where does the black exit the rear of the wing at the TE ? That is to say, does it exit on the center line of the TE, above the center line, Or below the center line?

The bottom line here is what to use as a datum line; the neutral thrust line or the angle of incidence through the wing root or what? It is important to know where to begin since all lines and measurements would be determined from that point as the paint scheme is laid out. What do you think?

OK. ALSO REREAD WHAT I WROTE ABOVE IN POST #496. IN THE PICTURES OF THE PROTOTYPE BELOW, THESE WERE EARLY PHOTOS. I LATER ADJUSTED THE DASH SIZE AND THE STRIPES A BIT MORE, (SEE THE WET RUNWAY PHOTO FOR FINAL LOOK). NOTICE IN THE FINAL PHOTO, I RAISED THE BLACK STRIP A LITTLE HIGHER THAN I SHOULD TO DE-EMPHASIZE THE HEIGHT OF THE WHITE STRIPE. IT LOOKS BETTER, BUT THAT BLACK STRIPE IS NOT TUCKED BELOW THE L.E. ANYMORE...IT IS EVEN WITH IT , (UNLIKE ED'S). THE FINAL PLAN SHOULD HAVE ACCOUNTED FOR ALL THESE SMALL "FLAWS" IN THE PROTOTYPE. THESE WERE THE "TWEAKS" WE MADE.

I STARTED WITH THE "TOP OF THE BLACK DASH" ON A LINE RUNNING THROUGH THE SPINNER ALONG THE THRUST LINE. WE ALL AGREED FROM THE BEGINNING THAT THE TOP OF THE DASH RAN THROUGH THE SPINNER.

THE TOP OF THE BOTTOM BLACK STRIPE SHOULD TUCK ABOUT 1/2 TO 1" BELOW THE L.E., AND IT SHOULD DISAPPEAR INTO THE FUSELAGE BOTTOM WHEN VIEWED FROM THE SIDE. THE SIZE OF THE DASH SHOULD BE ADJUSTED TO MAKE IT LOOK LIKE THE PHOTO...IF WE MADE THE RIGHT CORRECTIONS, IT SHOULD. NOTICE ON THE PROTOTYPE THE WHITE STRIPE IS TOO "TALL" COMPARED TO THE ORIGINAL, INDICATING THE WING WAS ABOUT 3/4" TOO LOW, AND THE FUSELAGE A BIT TOO TALL. ON THE PROTOTYPE I HAD NO CHOICE BUT TO LEAVE THE STRIPE AS THE LINES FELL, IN ORDER TO GET THE TOP OF THE BLACK STRIPE CORRECT AND THE TOP OF THE DASH CORRECT. THAT'S WHAT I MEANT BY SAYING THE LINES WILL "FALL" WHERE THEY WILL, AND IF THE PLAN IS RIGHT, THE DASH SHOULD CUT THROUGH THE WING, BUT ON THE PROTOTYPE IT DOESN'T.

WE TRIED TO ADJUST THE PLAN FOR THE FINAL KIT TO MAKE THE WHITE STRIPE A BIT SMALLER, AND MAKE THE STRIPES IN GENERAL FALL LIKE THEY DO IN THE PICTURE HERE.

AS I SAID ABOVE, THE TOP RED STRIPE THAT TURNS TO BLACK RUNS PARALLED TO THE OTHER LINES, AND TUCKS BELOW THE STAB.
