REFLECTOR: interference drag

[Alex Balic]

Looks really good Doug- certainly aesthetically pleasing - and it will
reduce interference drag- how much hard to tell, but you can make a fast
plane a few knots at a time!  I assume that you put some bid on there before
the primer... I have a measly 1.5" radius right now on the strake fuselage
intersection- might go fof the increase like you did- although it might
interfere at the rear windows...

I used pour foam to fill in the intersection between the strake and the
fuselage, then shaped it with some 40 grit sand paper glued around a Clorox
bottle. Here's what the fillet looks like with a Clorox bottle radius. By
doing the top and bottom of the wings, strakes, and winglet intersections
this way, I'm hoping to pick up a few extra mph.
