Mike,
There's a lot of and some complicated rigging on this beast. For example the cross brace wires between the fuselage and the lower wing in the "gap" between them is a real nasty challenge. I remember Chris Johnson being ecstatic when he finally wrestled that one to the ground and must say I had a near fit before succeeding! It takes a bit of forethought and planning, especially for the flight control wires, to ensure you get it all in and don't interfere with others. I have a plan, now it's the execution. Long forced breaks in the project induced by real life events are not helping the cause, I tend to "lose my place" and have to spend a lot of time just looking at where I am, going over the plans and references again, and trying to visualise the way ahead.
As for the detail that to me is one of the great joys of a build. I add whatever I can and, in this case, have lost track of all the modifications and extras I applied. Some is good, more is pretty rough. I hope with repetition to improve close to "Kong's" standard, whose scratch built additions I greatly admire. I'm sure like me you've thoroughly enjoyed and been inspired by his Ninak.
Your comments are much appreciated; don't hesitate to tackle the Bif, your skills will easily defeat the minor challenges of the design!
Cheers,
Lance
