Aero-Naut Centrepiece (Yoke)
Remember to order the centrepiece at least 2mm LARGER than your spinner diameter.
A smaller size is not appropriate and will not operate correctly.
The variant choices show the specification as follows:
size / pitch variation° / blade root width / centre bore / Aero-Naut reference number
All Centrepieces (Yokes) are high quality machined aluminium, accommodate blades with 8mm width roots, 3mm diameter root holes and come complete with blade bolts and nylon insert locking nuts.
The Centrepiece size refers to the distance between the blade securing hole centres.
