I’ve just built mine with the transmission kit, without doubt you have to pretend you’ve travelled back in time when building it, by that I mean with regards to manufacturing costs & assembly methods etc. It needs fettling & tinkering (ie, choosing to use a few alternative screws/using nyloc nuts here & there) to help make it all work nicely & reliably.
Now built, it feels very pretty tough tbh, though time will tell
