I used extruded polystyrene foam for the trailing edges, it is very stiff, easy to shape and it weighs nothing...
Aluminium tape give a good strength to the edge where the foam is thin.
While Oratex UL600 is very strong the 6000 feels almost destructible. This might be overkill but the landing gear take a lot of beating - particularly when passengers get in and out...
There is a video on YouTube where gravel is shot on Oratex 6000 with a slingshot at -25 C (-13F)... and another where they beat it with a hammer...
Did you use the Oratex hot melt adhesive on the polystyrene? I could not find any information online about compatibility. Thanks!
