How difficult is it to remove/replace the rotor blades?
Not difficult at all, it can be done by one person. Although rotor blades weigh approximately 80 to 110 lbs., including the hub bar, blades and bolts. The easiest way to do it, is by standing on a platform at the correct height, and lower or raise the rotors by a small block and tackle. A simple and light “A” frame is all that is needed. Finally, although the center of the UFO cabin is more than strong enough to take an average person’s weight, like me you would not want to scratch the lovely paintwork and we ask you not to stand on it.
