Carlton,my prop was made in South Africa,by George Killey,a professional prop maker.Some call it an "almost" constant speed prop.It bends forward at a load ,reducing the pitch somewhat.It is a beautifully laminated wooden prop ,covered with fibreglass,with stainless steel plated leading edge.His props are very popular here.Peter Deneker also is a professional prop maker here and makes beautiful props.I have one on my motor glider.His props are also laminated wood ,fibreglass covered.with kevlar/carbon fibre leading edges.If you require more info. please contact me,directly. Best Regards, Eric Evezard, South Africa.
