Sarolea Epervier
Saroléa was one of the most famous belgian motorcycle manufacturers installed at Herstal near Liège.
Early thirties, the young engineer Nicolas Lempereur developped a small two cylinders engine for aircraft.
Tested on the factory roof during october 1934, it was soon fitted on the first belgian HM-14 Pou du Ciel built especially for Saroléa by Mr Pregaldien. The first test flight happened unexpectedly on 22 august 1935. Soon after, it was also tested on the Tipsy S, the BAC Drone and the Saint-Hubert SBO.

Workshop
A workshop is a place where you will find lots of tools, but also humanity.
Georges Pradez was a radio presenter at the Belgian national radio as well as a talented scale modeler and an aviation fanatic. He was also an aviation storyteller and a source of ideas. From the creation of our association, he was always there when help was needed. When he passed away, we decided to give his name to BAPA’s workshop and a plate wearing his name was unveiled with members of his family and friends in attendance.
