This is bigger than my previous similar model .. and named Son of Loki (the previous one was called Loki and offspring are always better
)
It is hotwired EPS foam vacuum bagged with fiberglass, CF .. has a 16mm UD CF tape laid on top and bottom surface acting as a built-up spar.
Airfoil :- TL16 110% thickness.
The wing and vertical tails are full composite construction (fiberglass , Carbonfiber and vacuum bagged)
Initial CG (@7% SM) is at 20cm from LE apex
Special features1. 3x1mm CF strip slotted and epoxied into the LE... prevent dinks
2. The bottom hinged elevons also have a top mylar gap seal ... reduce drag
3. The servos, servo horn and push rods are embedded and completely enclosed within the wing. The push rods run through tunnels with the wing, and come out just near the TE ..... reduce drag.
4. The vertical fins are 2mm balsa , carbon fiber, fiber glass composite . They are strong/rigid, light, and thin...... less drag and weight.
6. 3D printed nose which supports the battery and also protects the nose during landing..
Electronics

2. 40a esc.
