It's o.k now guys after a lot of screaming and a whole pot of superglue they are all more or less intact, the reason my oldest tank being totally smashed is because the glue was old and therefor the tank was not as sturdy where as my newest tank's glue was very new and therefore strong. My oldest tank is the third i ever built, my oldest, a basalisk was converted into a pod-racer for a special participation game we did at my shop and the my first chimera is now in full time retirement because i no longer use chimeras with multi-lasers and heavy bolter, (2 heavy flamers killing even tau in cover on 2's with zip all armour save, it once wiped out half the enemy by itself)
