So, after quite a few scrapped ideas and a lot of doodles, I came up with a LF and a HF replace for the horrible Kushan imports we have now. I can also make a bomber with this idea, and have some ideas on touching up the HF, as I just added a couple of fins at the moment.
There isn't enough detail in either of them, right now they're just manipulated primitives. Its a base, but it needs a lot more work before I can say much.
Edit: I don't really like the shape, but eh, also hit f9.
the shape itself is nice - but the sizing is a problem. - these shisp look like they have a very small bridge instead of a cockpit. - so they look like tiny gunships rather than fighters.
From rear view the tails look ok...but from side view they dont realy fit with the rest of the ship imo...and the cockpit looks -as Jinx said - like a gunboat bridge.
Not fond of the fins on top (too curvey and don't really fit), but the rest is a solid base to work from. It's a bit rough, but it's a step in the right direction. The heavy fighter needs to use something other than a couple of fins on it to distinguish it from the LF. a blocky extension from the bottom, perhaps? Widening of the read exhausts and wings?
