As far as I know tissue tube hubs are legal for all classes and are a good choice. As I've said many times I never build props with a one piece spar. I'll take the weight gain of an extra piece of wood at the center or a tissue tube over the difficulty of making a spar in one piece.

I know this has been addressed many time but.. on duration models, is it common to make prop hubs out of tissue tubes to set blades one at a time rather than one long spar. I know I have seen plans to make two spars then glue them together and then set the blades on. Also on balsa hubs I have seen where you stack pieces then run your wire prop shaft thru both and make a right angle with the shaft and glue. Is that OK?
