    Why become a Subscribing Member?

    • 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.

I can't. I need 130 mph to do the 2nd half (outside half loop). To do it round I probably need something like 145-150. So far the best I can keep as I finish the 1st half is 110. So after several incipient spins and a tailslide, I gave this up as outside my mojo. Curious if I've hit a 4-cylinder biplane limit or a personal one.
