Howdy,
I sketched some ships in 3d for my game group and the GM thinks it works well as a Zygerrian fighter built around a railgun that can fire normal or ion projectiles to disable larger ships.
The current model is here: https://sketchfab.com/models/cd3ee915e0ee4fc0a438715d13f1eb63
The collection of models related to the Zygerrian Fighter are here and won't require a password to access, even if the above like does: https://sketchfab.com/models/cd3ee915e0ee4fc0a438715d13f1eb63)
In terms of size it's about the same wingspan as an X-Wing, though there's more bulk.
Not a lot has been defined in RPG terms yet and while I'm not a major X-Wing player, here's what I have so far:
Attack: 2
Defense: 1
Hull: 4
Shield: 3
Actions: Boost, Evade, Focus, Target Lock
Maneuver Dial: Y-Wing
Upgrade Bar: Illicit, Cannon, Torpedo, System, Missile
Title: Oir-Gum Cannon (Optional Ion Railgun Munition)
Attack: 4
Range: 2-3
Declare if the attack is going to be regular or ion before rolling the dice. If Ion is selected, add a stress token to your ship.
Regular: No Special Rules
Ion: If this attack hits, the defender suffers 1 critical damage and receives 1 ion token. Then cancel all dice results.
Remove Missile from upgrade bar
Remove Boost from action bar
