A very good friend of mine, in a very successful attempt to get me hook on pattern, gave me a Dirty Birdy he had built with a 91 Surpass in it. This Dirty Birdy had a fiberglass fuselage which he had modified to include a belly pan beneath the wing to encorporate an open pipe tunnel. The 91 Surpass was fitted with an O.S. flex header and a silencer (very quiet setup).

This plane was built as a tail dragger with retracts. Very cool airplane. I immediately fell in love with it and have ever since been hooked on pattern.

I've tried to include a photo of the plane and if anyone is interested I can post a picture or two of the underside showing the tunnel, header and silencer.

Sincerely,

Steve T.
