I used two 12cm wide fiber-wood strips...they bend easily and easy to work with...I had em bolted 3cm apart and used Polystyrene to evenly space them from each other along the bow.
The HUD is much trickier though. The hud is a reflective glass that receives mirrored projection from another reflective glass underneath, which is being projected via lcd monitor in its turn. mirrors are useless cause projection is being duplicated when rotated to a certain degree thats why i used reflective glass. its completely transparent and reflective only on one side.
the hud image was extracted by tweaking lua files . remmember that it is a collimator in nature so i had to tweak the hud lua files to change its size and make it "common" . :pilotfly:
