Folding Props and Spinners

These props have a unique shape and have been designed by a world class designer which has been patented. The spinners are spun from aluminium making them very strong and light. They feature a cooling hole in the centre to allow motors in molded gliders to be cooled with very little drag. The props will have to be drilled out slightly to fit these spinners.
The props have a 6mm root. The spinners can take up to an 8mm root blade but are supplied with spacers to enable correct fit of the 6mm root blades.
The retaining nuts should be secured using thread lock or nut lock to prevent then coming loose in operation.
