Planning for my next build - Grahm Jones' 1972 Soar Jet (https://outerzone.co.uk/plan_details.asp?ID=9235)
I'll be making some aesthetic adjustments to the top of the fuselage for reasons of personal taste.
Here's the specs:
Span: 72"
Airfoil: unknown symetrical
Root: 19.75"
Tip 6.5"
LE sweep: 28.8 deg
Twist: none
Elevons are a little less than 1/2 span and 1/4 chord at the wingtips.
Elevons are set with about 11 degrees up or 3/8" at the TE.
Question for you aero-gurus: IF one of you were building this, would you bother to change up the airfoils to something "better"? On a "vintage" sport design like this, would there even be any noticeable improvements from using reflexed airfoils given the old-school construction (built up balsa D-box wing with capstrips)?
