Hi!
I made a fast diorama with new PZL P.7a from Arma Hobby. I bought overtrees kit and builded it without any additions except dampers tapes. Support is from wood, cloud is a painted rock, air streaks are from cotton swab soaked with CA glue and number 7 is made from plastic plate. Kit is nice but needs cleaning and puttying some plastic recesses. After that work everthing fits perfectly.
