JS customized color RZ-2 A-wing Interceptor. Black color to more easily blend into the darkness of space while yellow is a typical color for Sentinel adherent.
And for the modifications, JS did two things:
#1. JS had his starfighter coated with sensor-scattering ferrosphere paint, so enemy can hardly detect it by sensors.
#2. He mounted an additional laser cannon on the interceptor fore section, right in front of the cockpit. This modification increases the firepower of his A-wing, but reducing power available for other functions like speed or shields. And unlike the two laser cannons on the right and left wing which can angle sixty degrees up or down, this middle laser cannon can only shoot straight.

I meticulously recreated the below linked image on paint and then painted it in the colors of Warpaths RZ2 A-wing.
the reason i recreated this image is because the original image was horribly light in color.

I'm sorry for such a cruddy picture; the printer scanner I usually use won't connect to my computer, so I took a picture with my phone.

Yes, it is designed a little differently than other A-wings: the ram is a bit longer with two points on it; the thrusters are set between the fins and not inside of them; I also added a little wave of armor along each side of the cockpit; and, not sure if this is allowable or not, I upgraded the armament from 2 single laser cannons to 2 dual laser cannons.
