Beautiful work, and I really appreciate your answering my questions. I'm at a similar place on my build of the same model.
How did you drill the holes for the rudder and stabilizer rigging? I tried with my smallest bit (.3 mm) and given that the plastic piece is only around .5mm, it was really hard to drill centrally, and the remaining plastic ring was really thin. I ended up cheating and gluing the line behind the attachment and not through it. What size bit did you use, and was it any special kind?
thanks!
