New 3.5m Thermal glider composite build

Just wanted to share our clubs new 3.5 meter glider build. It's been a great team effort and we are getting close. The airfoil is Mark Drela's Supra but we changed up the fuse to a saddle mount.
The nose is slip-in to the fuse so we machined CNC molds to create either a electric version or a winch launch version. Bladder system to create all fuse parts. Vert stab is vacuum bagged as well as all wing skins. The wing is full on hollow core using 1.5mm depron for core material.
Full flying horz stab again in molds. Everything pre-painted in the molds.
