Used carbon fibre rod as fuselage to reduce the weight in V4 along with other modifications listed below.

• Printed the wing cover with 0.08mm layer height ( minimum with 0.4mm nozzle in bambu lab). Experimented with flow rate and pattern fill to maker stronger layer at 0.08mm layer height.

• Reduced the wing frame elements thickness to 65-70% since I figured tension from wing cover is keeping the wing structurally stable
