If you need to make undercarriage struts, I recommend brass "strutz" material - I bent up a set for my 1:48 Jager Albatros C.X, which is a very heavy model, to replace their white metal struts and they have held up great. I glued mine with CA but I would recommend something a little more solid, like solder of some description. I created a jig to bend them at the right diameter as well - basically a flat styrene sheet with the strut plan view angles marked on it, and a piece of circular shaped styrene at the right radius of the bend glued perpendicular to the flat sheet - allowed me to bend it around the circular protrusion and get all the right angles (but was still tricky to keep flat...)
Not sure where you can get this material though...?
