    • 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.
    • 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.

Hi, I am from SW of France and I am just at the end of my Skybolt project.
I have a Conti IO-470-D, but due to the French stupid "bureaucratie" I can't use it.
I have a Conti E-225-4 that I can buy, so my question is : ok or not for evryday use and some aerobatics?
