| A nine cylinder radial engine. It's a faithful
replica of an actual Pratt and Whitney Wasp Jr. aircraft engine. I've recently been in
contact with the builder of this, and other motors, he has a web site dedicated to miniature
engines. He tells me that the motor is 1/4 scale, and measures 12.5 inches diameter
overall. Photo courtesy of Paul Knapp |
