I ordered this propeller 12/15/2021, so definitely some extended lead time. Whirl Wind is an excellent vendor to deal with and they kept me informed throughout the process. Aside from an extensive backlog of orders that they've received, they customized my unit to be more appropriate for my engine power that was developed through dyno tested. One of the more difficult items was the spinner. I have a 15" spinner bowl on my ShowPlanes cowl, which is larger than the 13" spinner for the stock Van's cowl; Whirl Wind had to do design and retooling and testing to develop this spinner for the new larger 300 series prop. The good news is that they are now available, and although I got one of the first ones - they are pumping them out to fulfill back orders.
