Magnetize a Zergling once and field it three ways. This kit covers the hip joint and the wing mounts, so one model can be built as a Zergling, swapped over to a Swarmling, or given the Raptor wings, all without gluing the body halves shut. Magnets in this kit Magnet size Where it goes 4mm x 1mm disc Interior of the right side hip socket 3mm x 6mm cylinder Hip connection point, the swap joint 2mm x 2mm Wing connection point on each body half 3mm x 0.5mm disc Raptor wing tips What it fits Every Zergling in the plastic set can run as a Zergling or a Swarmling. Zerglings A, B, D and E also have the moulded wing spot, so those four can take the Raptor wings. The Swarmling body half has no wing mount, so it never gets drilled. Installation Three steps, and it does involve drilling. You will need a large pin vise with 2mm, 3mm and 4mm bits, super glue, a needle file, and a Magnicator to keep polarity straight. Every step is photographed in the Zergling Magnetization Kit Guide. All magnets are N52 neodymium.
