Volmer VJ-21 Jaybird
![]() The Jarvis Jaybird design was acquired by Volmer Jensen as homebuilt project soon after World War II and became the VJ-21 Jaybird with retractable wheels and 75hp Continental A75 engine.
The 1947 Volmer Jaybird all-metal evolution features a pod nacelle with a pusher engine and has monowheel gear with outriggers on the wings. Reportedly more than 900 plans sold to builders through the 1960s.
A later owner (ca.1960) put a 125hp Continental C125 in, repositioned wings slightly lower and added small auxiliary fins.
