s. The kits proved popular and Mather expanded to market complete aircraft based on the basic Quicksilver layout. The first two aircraft in the series were the two-seat double surface wing Sport 1000 and the two-seat single surface wing Sprint 1000. The series all share similar construction featuring a bolted
