    • 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.

Hey Folks, my engine runs a bit hot for my tastes.... The cowl is closed with the exception of underneath, there is a small opening for exhaust and air.. What is the CW on putting exit vents in? I appreciate all of your collective and individual expertise.
Thoughts??

Thanks in advance...
