The current national record for F1M in Cat3 (West Baden) is 21:11. The
new record for F1D at the same site is 27:11. The F1D Junior by Leo
Pilachowski is another alternative. Or you can do what most of us do and
start out by building and flying simpler AMA classes like Limited
Pennyplan, A6, F1L, etc.
