Again, a (British term) “Lovely” set of cast metal gear to help your model stand on its own without looking like Bambi on pond ice after a few months.
This set is the usual SAC total replacement of the kit items, with improved assembly and ease of installation. Whereas on this kit you are required to capture a wire between the strut halves for strength (which is still an improvement over total plastic gear), SAC saves you the effort of having to clean up the parts after assembly.
The other benefit I n this case is the axle assemblies are metal versus plastic. No broken off axles after a hard landing (just bend the gear back into place)
