Homemade coaxial helicopter rotor blade close up
The first rotor blade complete except end closures. Not saying this is 100% the correct way to make a rotor blade, I have not built a rotor blade before but it is the way I have chosen and the results are to be established.
Making the rotor blades is certainly one of the more challenging aspects of building a helicopter. If you can do that successfully chances are the rest of it will be achievable. There is a huge amount of time in making the blades and the materials certainly add up.
Airfoil NACA 0012
Chord 4.75"
