5 blade rotor technique
A simple solution for a 5 bladed rotor system for helicopters. The five plates are obviously the base of individual rotor blades, spaced at 72 degree intervals from each other. The lifebuoy spins freely around the smaller technic gear while resting on the larger gear. The dish is then used as a cover for the rotor assembly and keeps them from spinning up and off the mast, put too much pressure on it and it acts as a rotor brake though. The whole assembly allows for a little bit of rotor droop or flex upwards before the parts begin to catch on each other.
