Roger Purcell's Scream Machine!!
Those of you who are fans of the Don Muddiman Flying machine will appreciate the Scream Machine designed by Roger Purcell.
If you are familiar with the construction of the Flying Machine, the Scream Machine will be familiar, mostly because Purcell and Muddiman are friends, lived near each other in Central Florida, and flew together for many years. In fact, Purcell states that Muddiman was his mentor in high speed sport aerobatics years ago.
Look at the pics below of my 44" and 50" Scream Machines. The 50" is powered by an OS .55 AX with tuned pipe per Don Muddiman's set-up. The 44" is a REAL SCREAMER with a Jett .50 BSE!!! Both airframes were built personally by Roger, and are two of only a known few remaining.
