I made this today because I have an otter at third scale that was not landing well with a default Realflight prop that looked scale (excessive spool down times). It is a prop that at zero RPMs it feathers for lower drag. However as rpms increase the prop enters a fixed pitch prop. It uses realflight's folding propeller with some crafty pivots. Not a v-pitch. It is plug and play on any aircraft (aka change prop then fly). It also has a paddle prop design.
