syshang, take your time and always ask yourself "how can I improve? How can I do it better?". It really boosted my skills
ferrarifan, proppeler hub is made of thin printing paper. It was wrapped tight around steel rod and covered with a cyanoacrylate glue to harden it. Then I mounted it on drill and sanded it out.
About this proppelers blade twist. I always glue leading edge first with elastic glue such as PVA glue (white waterbased glue used by carpenters) so it won't crack while changing curvature. Then I twist blade in my fingers and glue trailing edge in small sections (5mm at once). Two halves rarely fit perfect so I have to cut visible surplus at the end.
