Here's the intended project.

Specs from the Aviation Design site.
Span - 49’’.....Length - 59’’
Weight in EDF version - 7.1 lbs without batteries, 9.3 lbs with batteries
Fan -1 fan 90 mm, 3 kg (6.6 lbs) to 4 kg (8.8 lbs) thrust
100 A controller
8S or 9 S lipo pack, from 3400 to 4400 mah

If you read the first post, I threw most of these specs out. Had to be some what bigger. My specs:
Span-52" ...Length-61.5"
Weight with batteries--approx 11lb
Fan- JetFan90/Het 1200kv approx thrust 11.5lb/5.25Kg
120A ESC
12S-5000, 35/70C
Also added, Flaps, and rudders.
The bulk of my extra weight is in the batteries and additional servos.

I'm not in a big hurry on this, so no build thread. I have the core blanks, hot wired out, but left the wing panels over size in case this doesn't work as planned, I can use them later. And a whole bundle of FFF, to experiment with! 25x2'x4' pieces. I have no illusions on how this my pan out.. This may be harder than making a composite fuse! I'm no John Morgan or a humbertomelo.

I recall seeing the Scorpion years ago and thought it was rather unique. Had seen Hoover or die's build on this, thought I'd give it a try. Link to his thead below.
Scratch-Built Mini Scorpion 60"L X 44"W

Not to much to show, but alot has been done. As mentioned core blanks cut, airfoil templates done, all measurments scaled out.
