RDF Loop Antenna for HSD Me-262

thingiverse

This is a WW2 German RDF antenna. It is specifically designed to fit the HSD 1890mm Me-262 Radio Control model, but could work for others. For this 1890mm span model the antenna file here should be sized up by a factor of 1.24x for printing. Since that model is 1:6.6 scale, and the antenna needs to be sized up by 1.24x to fit, the native scale of the STL File is about 1:8.2. Note that it has a small curvature to match the curvature of the fuselage, and it also slopes down a little at the back to match the fact that the fuse it tapering toward the empennage. These slopes and curvatures might not be suitable for other planes. Note that there is a great picture of this antenna on the Me-262 of the Deutsches Museum (currently at Oberschleissheim) at 14:06 in this video: https://www.youtube.com/watch?v=IrH2duoxsOs&t=846s The little tab on the bottom is to anchor it into the foam. I just pressed it in, then took a knife and cut away the excess foam from the dent. After that it sits flush and can be glued on easily. EDIT: I uploaded a different version "r4" which I think is better. The antenna tilts relative to the base, so that the base can be flush with the fuse and uniformly thick. In r3, the base is horizontal so that it actually gets thicker at the back to compensate for the down-slope of the fuse.
