Hint....
Hint...those are full-length yardsticks in the pics...
I'm guessing around 40 inches..maybe 42...
Ya know...hadn't thought about it...but it does kinda have a lumbering...menacing "Vulcan" look to it....not intentional...but cool, none-the-less..
Tips are 10 inches NOT including 3 inch elevons. Made from 3/8x4x48 sheets.
I hot-wired the taper paralell to the chord (from root to tip) symetrically at the rear about 6 inches from trailing edge, left it about 1/2 inch thick. The leading edge is flat-bottom style with just a hint of lower at the tips to get a little washout effect. I did round the bottom leading edge just a tad...like 1/4 inch...but for the most part its a FLAT wing...
If you look at the first post (scroll up on the RCU link above I have a pic of what I did withthe foam... cut the sweep and added the cut material to the front... you can build TWO of these from a 4ftx8ft sheet of 2 in foam if you do it right....was 12.99 at Home Depot. So, about 7 worth of foam...
I'll see if I can take a couple pics of the tip and post here...
Good Luck!
