Scale Aircraft Conversions (SAC) has a long history of creating great metal drop-in replacement landing gear for scale model aircraft. This set is for the 1/35 scale Border models B5N2 Kate. You can see in the review photos a side-by-side comparison of the kit gear and the replacement gear set. They are a spot-on match. Given the size of the model, it will benefit from a stronger set of metal gear legs.
In the blister pack you will find (2 each) main gear legs with associated scissor links as well as a tail wheel bracket. Like the kit polystyrene counterparts, you will want to start the prep process by removing any seam lines and gently straightening any bends introduced during the shipping process. Prep the parts with a metal-compatible primer and paint with your favorite hobby paint. As a reminder, metal parts can not be glued with plastic model cement and an epoxy or superglue will need to be used.
