Looks like you're off to a solid start, Przemol! I really enjoy seeing how some of you guys drill and pin more positive connection points since that's a technique with which I've experienced mixed results. I'll be paying close attention to this topic of yours since I've got a Lukgraph Halberstadt in the stash and hope to add some more of their kits soon.
Looks like you are off to a great start. I'm sorry if I missed this point if you already mentioned it, but are the PE reinforcements for the control horns part of the kit?
