In a news item published in 2010 in the Dargaville newspaper, it is published that Allan Fillery designed and built a radial engine of seven cylinders for general aviation that we see in the illustration below, which appeared together with the news.

"Allan with his radial engine" (PiP)

-It is mentioned that it is a four-stroke engine that displaces four liters in total. It has digital operation control, and it has side valves to reduce the front diameter.

-The wax molds for block and cylinder castings are made by himself. In total there are 32 molds.

-The valves are at the rear of the cylinders. The engine is currently in development.

From Appendix 11: We have found information that before the 7-cylinder engine he has made a 9-cylinder radial engine for a model.
