Not bad in general, but I'd make a few adjustments.
I'd probably adjust the Heavy Bolter in the scouts into a Missile Launcher, and change the Plasma Cannon into a Missile Launcher as well. These weapons are a little bit better for utility, and a little bit more accurate as anti-armor. You have a decent amount of plasma guns around for anti armor.
The Storm Talon confuses me. The Skyhammer's not a bad missile launcher, but it really seems to be at odd with the rest of the fighter. If you're using the Assault Cannons, you're better off with Heavy Bolters for a cheaper zooming around fly-over strafing run. If you're just planning on leaving him hovering in a corner sniping you'd be better off running a landspeeder or two with Typhoon Launchers. If you wanted anti tank, you'd need the lascannons. Right now you just have flying autocannons with extreme range... if that's the firepower you wanted, run a Rifleman Dread. Or two.
