I have a Whirlwind ground adjustable prop (GA-J2B) and carbon fiber spinner for sale.  It's for a Jabiru/Camit 3300 and was on Zenith 601XL.  This prop and spinner have less than 30 hours on them.  They are in excellent condition.  The prop is currently discontinued on their website so I asked about the GA-UL260 prop because the specs seem to be identical.  Here's is the response:

Hello Randy,

We discontinued the GA-J2B propeller due to production capacity issues.  It may be returned to production at some point in the future.  The UL260 propeller is a different blade and is not suitable for the Jabiru engine.

I wish I had a better answer for you.

Sincerely,

Patti

I thought I'd list it here before Barnstormers.  I'd like $1400 for prop & spinner.
