Scale Aircraft Conversions makes various landing gear sets out of lead-free white metal. Some come with the wheels attached if needed, like this set for the Buccaneer, where the kits wheels are molded onto the struts. Others might have the wheel bay included to help with added weight, but most only come with the new landing gear struts. I had the Airfix model so I don’t know how the CMR wheels are molded.
The detail of the metal parts is much crisper and looks flawless. The advantage to these parts is their strength and that they won’t warp under the kit’s weight over time. They will also hold up well while you work with them – no accidentally snapping them apart. To attach the new landing gear, you will need to use CA glue. On their web site they recommend a thicker gap-filling CA glue so that you can position them the way you want and then use an accelerator to bond the parts instantly.
