Hi Super Cub,
still building but 500 hrs is realistic. As a retired ATP it takes probably ~100 hrs more for me. No compromises in details ;-).
It takes less than two (2) minutes to fold/unfold the wings and you can even do it while having full tanks.
To me Trial/Trail is like a modern Super Cub. Been flying factory planes in Italy twice. Fell in love the first time, had to go back next year after flying season ended in Finland to have fun.
My friend who finished his Corby Starlet in 2015 is waiting his kit to arrive in August.
In YouTube you can see how easy the wings are to fold/unfold. Just search Nando Groppo Trail.
Safe flights,
Ari
