Hi Campeon:
I am glad that you are considering it. If you can imagine it, you can do it!
Looking forward to the Boxy Pucara; And maybe some of the lesser-known light helicopters of the conflict, like the Scout or the Wasp.
Here is my little grain of salt. Maybe not the fighter you were waiting for but the Skyvan from the Prefectura Naval. It is boxy because the plane itself is boxy.
I am reloading it although it should be there somewhere. To make it 1/250 print it at 120% and for 1/200 print it in 150% (or send me a PM if needed).
All the background information You may find it here:
