I thought the Takom St Chamond was 'challenging', OK, fussy and frustrating, but the Mark IV (female) build I'm currently doing is an act of masochism, pointlessly complex, not close to 'builder friendly'. (Rant off)
I'm guessing its mainly the tracks? 1000 parts for those alone is a bit heavy. It's worth buying the separate ready made plates. One complete track goes together in just a few mins.
