I have found a black and white picture in FlightLine of a (yellow?) Premier AX3 at the 1990 BMAA show. There is a sign saying it is powered by a Rotax 508, which is a two cylinder 4 stroke. It must have been an imported aircraft, because it says AX3 by Ultralair on it, rather than Cyclone AX3. The tail is not visible, so can't see a reg.
