Time for a quick bit of hobby advice regarding the Leman Russ Demolisher kit. This kit is super easy to build and keep all your weapons options available, so you can switch weapons out and have any of the three russes in the demolisher kit, without having to buy another tank. This way you can build one tank, and it can still be a punisher, executioner, or even a demolisher.
Because of the way the main gun weapons fit into the turret, glue is not required, so once you have your turret built, and the weapons put together, STOP with the glue! And because the top piece of each weapon slides into the turret, it fits nice and snug, no magnets required. So this isn't even advanced customization. Then all you have to do is base coat it, and paint it.
The executioner, again, fits perfectly, no hands, no glue.
And here it is painted.
Slides in and out at will. Note the same goes for all the sponson and hull weapons.
I know this is not the most advanced hobby post, but I didn't realize they could all fit together at first, so I could have already had two more of these turrets with all three of their weapon options available. Lesson learned. The standard leman russ is a bit harder, but once I pick up another kit I will take a crack at it and see if we can keep all 4 of those weapon options unglued.
Hope this is helpful and keeps you options open.
