New/Unused Whirl Wind Propeller For Sale

I have a new unused Whirl Wind GA-J2B Propeller with a nine inch carbon fiber spinner and bulkhead for sale.  This is a 65" ground adjustable designed for a Rotax or Jabiru engine.  The Aircraft Spruce price for the propeller alone is $1,550.  I'm asking $1,000 for the prop and spinner.  This price is firm and you cover the shipping.  The reason I'm selling the prop is I'm upgrading to a three blade Catto. See More

Second Wing

Finally finished with second wing except the wing tip that I hope to get to this week.  Wanted to get done before July 4th but screwed up top rear skin.  Ordered new sheet of aluminum (still thinking could get done in my time line) and the sheet was damaged in shipping.  Re-ordered and got it a few days later.  Now shock and horror I start to think about match drilling all of the holes, weird myself out, so I put it off until after the forth so I don't have to rush.  Now (as we know how this…See More
