Kotobukiya M.S.G MH22 Heavy Weapon Unit Exenith Wing
This unit aims to reach the top of the Heavy Weapon series by including elements of Transformation, Fusion, and Unlimited Customization that makes products such as Unite Sword, Mega Slash Edge, and Gun Blade Lance so popular. The flying unit can be removed from the main unit and can be assembled with its own weapons, armor, and joint parts. And with both units that can each be equipped and assembled in its own manner, you can enjoy many variations of assembly and create larger weapons of your own.
Whilst no scale is given it could be used with 1/144 or 1/100 scales quite successfully.
