For my builds (all 1:72) I drill and thread the rigging. I have quite a few pushers in the stash (including the Eduard DH-2) and so far my plan is to use plastic stock rod for the tail booms and drill as before. Maybe even square section rod, drill, then sand to what will pass for round...I expect a bit of trial and error before I find a method that works. I used quite a few drill bits on my Bleriot and will probably use quite a few more on these pushers....one thing I do know, I won't be using the brass rod supplied with some of these kits (eg Pegasus Vickers Gunbus).
