Friendly recommendation - don´t build your own blades. Blade construction is definitelly not simple. Look to the market and buy a set of blades from some exerienced company. Ideally with rotor head and hub bar. Blade shape and profile seems to be easy but CG position of rotor blade is not so easy to achieve. Wooden rotor blades had sometimes a "hammer like" ballancing near the blade end. Aluminum or composite blades have a lot of mass in the front.
