I used the sketches from Joan's Fighting Spacecraft in Claw Marks from WC1 and basically measured everything out (large blocks are 2.5m^2, small blocks are 0.5m^2, so they're actually full size in-game. I did hit a slight problem with the relative size of the fighters though, as I think has been discussed in the past. To fit a Raptor out of the launch tubes, I had to make some modifications to the mid-ship wings compared with the original drawing, and with the best will in the world this 'Claw with these fighters is only ever going to have 2 launch tubes. I think I could just about squeeze in 104 fighters, but at these scales the ship would be basically unworkable and all other ship functions would be relegated to the aft wings, super- and sub-structures.
The same problem also applies to the Kilrathi ships, as the canon Fralthi is supposed to house 20 fighters - I managed to squeeze them in (just - 6 Krant, 6 Gratha and 8 Salthi) but only by using some creative thinking. I am considering rescaling the fighters but they'll lose a lot of detail in the process :-(
If anyone has alternative / better scaled statistics for the size of the WC1 fighters (Kilrathi and Terran) I'd be very interested in those. I've already applied the 19:24 resize of the Rapier from WC2 to all the fighter craft and the size is still pretty bonkers.
