Scale Aircraft Conversions specializes in white-metal replacement parts. Its line of replacement landing gear has been expanded to include a set for the 1/48 Kinetic Super Etendard.
The set includes 8 parts with the following breakdown: two main landing gear struts; a two part nose wheel, plus actuator arms; and a nose wheel fork. The parts are finely molded in white metal. These parts are drop-in replacements for the plastic parts.
I should say that these parts are more than just drop-in replacements. Many of the white metal parts actually are the equivalent to several plastic parts, so you have an easier job of assembling the landing gear, for instance, as you have fewer parts to deal with.
