This Piper Tri-Pacer VH-MTS walkaround gallery comes to you courtesy of Deborah Fanning, owner of "Mike" the trike, and Andy at Rolfe Aviation for letting me into the hangar where it lives. VH-MTS, cn: 22-5593 is a 1957 build Piper Tri-Pacer that was first registered in Australia in March 1958. It is a regular visitor to various fly-ins and airshows around Australia and it is in quite outstanding condition.
