Progressing nicely, Reinhard @grimreaper

Looking great, my friend @grimreaper!

added the multpart PE FOD flaps
there small areas that you would have to bend sideways to get the two hinges of each flap, but that´s almost impossible without damaging the flaps, therefore my dad did cut them away, maybe he tries to recreate them with some small plastic pieces

all the little parts added on under and upperside
