• The Biplane Forum is a large global active community of biplane builders, owners and pilots. From Pitts to Skybolts, to older barnstormers, all types are welcome. In addition to our active community, our content boasts exhaustive technical information which is often sought after for projects and maintenance. This information has accumulated over the 12+ years the forum has been in existence.

    The Biplane Forum is a private community. Subscriptions are only $29.95/year to gain access to this great community and unmatched source of information not found anywhere else on the web. We are also a great resource for non biplane users, since many GA aircraft are built the same way (fabric and tube construction).

74in diameter and pitched to 54. It has laminated leading edge protection.

This prop has never flown. It was ordered last spring for my project, used for some test engine runs. but never spun passed 1500rpm. Always stored horizontally in my dry hangar.

This prop is for an O-320 with 3/8 propeller bolts. I will include a bolt set from Saber Mfg (length is set for a 1/2 crush plate and .080 spinner bulkheads)

Asking 500$
