jorod74, see below for a few pictures of the 1:18 scale HO-229. This was a 1:18 scale-model (or rather, work of art) by fellow board member Pickelhaube. He designed and built the model from scratch. It is made mostly of cast resin and the molds no longer exist. Pickelhaube spent over a year designing the plane, then finally casting hundreds of parts and making both a kit version and a fully-built version. Mine (a full built version) is one of fewer than 50 in existence
Here's a few pics both "in flight" and "on the ground" with the 21c ME-262A and some figures in the mix for size comparison:
