I added some missing bolts, sanding the left wall of the engine compartment to the real thickness from 1,2 mm to 0,6 mm because I want to leave the left engine hatch open to see the engine.
I also made cable plugs and handles and making holes in radio rack dampers for radio hardware (sorry, the transmitter and receiver are upside down, just noticed, but not glued yet).
Although the Dragon model is good, it lacks a lot of detail. I made from scratch a commander's headset connection box with a tube for the cable, and another bigger box (I don't know what it is)
I made from scratch the floor of the fighting compartment (for some reason, Dragon did not provide that). Then I combined the cannon base, floor, and gearbox shaft into one block
