• 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 $49.99/year or $6.99/month 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). Annual membership also comes with two BiplaneForum.com decals.



Less love for the S-2A (regarding STCs)?

Hi all,

I've noticed that even though all the 2 seaters are on the same Type Certificate Data Sheet (TCDS), they are commonly left off the Approved Model Lists of various STCs. I've noticed the JPI EDM-900 engine monitor STC says to look at their AML which lists only S-2B and S-2C. This engine analyzer can be set up for 4 or 6 cylinder so it's not a hardware limitation.

The EarthX battery website lists pending STC approval for their lithium battery for the S-2B and S-2C only coming in Q2 of 2023. I believe they're all the same voltage and same battery required?

Any ideas why the A model gets left out of the fun? I think there are around 270 of them while there are only around 90 C models?
