Hello - looking for information on the Firefly. I came across a post mentioning “well-known“ low speed issues, but no elaboration. Can any Firefly owners comment on this?
What airfoil is used on the Firefly? It reminds me of a Liebeck style airfoil - slightly concave on the back side.
Does anyone have a builder’s manual for loan, or for sale?
And last, does anyone have experience with the Hirth F23 engine? Any significant difference in weight compared to the Rotax 447 with gearbox?
Thanks!
