• 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.

Unrelated to biplanes, but you all have such a wealth of experience. I am working on my garage project. It has a Revmaster 2100D engine. The oil cooler mounts on the bottom of the engine (see attached photo). The oil cooler already has a built in mounting bracket and sort of a plenum. My lower cowl has a slot for cool air to reach the oil cooler (see attached photo). I was wondering what I should do to ensure maximum cooling of the oil. The oil cooler has no openings or pass through's from top to bottom, so cooling air needs to go over the fins, top and bottom. I don’t fancy myself as a fabricator, so looking for a simple solution. Fire away!
