HSDE/VT Controllers

HPI traces its heritage to the Hawker Siddeley Dynamics Engineering (HSDE) Company which supplied the original DIGICON® controllers to Allison. Many of HPI’s engineers worked for HSDE and were responsible for the development of the Allison 501-KB5 control system. HPI has been supporting the repair work on the DIGICON product line since the closure of Vosper Thornycroft Controls (VT Controls) and HSDE.
