Of those, the only one I own any examples of is the micro Ostrogoth, with a few for non-Battletech purposes. In fact, I'm expecting a box containing more of them to arrive today. :)
I love this fighter. The compact size makes it perfect for fleet battles, yet the details are very crisp and it's easy to recognize the fighter class at a glance.
I've only got two issues with it, and one of them is extremely minor, and I suspect may be insurmountable due to the tiny size.
The minor one is the missile racks. The holes are so tiny, it can be difficult to paint without losing them entirely. Again though, I suspect that's an issue with all micro fighters. It can't be easy to fit fifteen holes onto a panel that's less than 2mm across.
My only other issue is the engines, or lack thereof. I have no idea where the thrust actually comes out, so I'm probably just going to pick a nice looking rear panel or two and paint it all nuclear-glow-y.
Overall, I love this fighter, and would give it a 9 out of 10. I'm assuming the Wusun is just as good, and am already trying to think of a fleet it might go well in. :)
Given how well you can do tiny units with crisp detail, are there any plans for you to tackle any battle armor sometime in the future?
