Mal, they were alredy using FuG 240 Berlin radar with a dish instead of anthennas under a covered radom in some planes at the end of the war. Did you check out AMTech's
Nacht Jager Hückebein ? Has a similar idea. What brand and scale is your Ta 183 if it is not too personal? :-) I am trying to make NJ Horten 229 V7 with FuG240 (which is also PM and built up with that radar but I didn't find it convinceing enough so I did some manupilation on it). I hope to finish it and put it around here somewhere some time but I am too lazy:} I decided to paint reverse pattern on it too (tat is if I ever menage to finish it of course).
Peter, I guess Splinter will be intresting too. I look forward to see how it ends up. Cheers guys, be well ....
