I rang Simon a few weeks back for a pair of 60mm. Kort blade props. with 5mm. threads. Got through straight away, think it was a friday afternoon, and was advised that he had them on the shelf but had read previous comments. Came thursday morning with a thump on the door mat, two props, just needed a bit of filing to fit into nozzles but worth every penny. No complaints about that service.
Wiggy.
