[G'day, Michael.
I'm a few steps behind you. I used the HGW PE set and found it quite useful. I plan to add the turnbuckles, etc. later this week. Are you planning on fully rigging the rudder bar? This is my first attempt at this sort of rigging with hardware but I am taking it slowly and look forward to it.
Yes, mate, I rigged the rudder bar- it's easy to see the rigging exit behind the seat, when looking into the cockpit. I put eyelets in the bar and then just looped the line through, using short lengths of MFH flexible 0.4mm tubing for the turnbuckles. It's not that hard, really, it's just time consuming. What I trying to do now is work out a way to tension the lines in both the Pup and the Tripe. There's some good build logs with some good ideas. I've just got to pick the one that works best for me.
Rigging kept me from trying biplanes for years. But I couldn't resist WNW's Pfalz D.IIIa. The blokes here gave me good advice and eventually I got it rigged. Further experimentation gave me a method that works well for me (see my N.28 build log). When I realised I
like rigging, I knew I was a hopeless case.

Cheers.
Dal.
