I've got my Wyvern put together and I've got to say, it's a very nice little kits. I love the look of it and it was a pleasure to put together. My only niggle is that the join between the disc the weapons are mounted on and the support arms is very swallow and sort of results in a bit of wobbly weapon syndrome. Other than that, it's great.
Obviously, I've added track guards which I had to cut down so they didn't interfere with the turret but that was a real easy job with a hobby saw and I definitely it improves the look of it. I also added a bit of battle damage and filled in the side panels so I could do ident patches.
All I've got to do now is finish of my VL vets (they're half done) and then I can get stuck into it and get it on the table guys!
