Hinge size should not matter - either will do the 50 fine, its amount of glue thats the issue but good question... you did use the thin type right Sprink ?

Just had this mail in from some one satisfied...

Its exactly how I felt and why I built a second airframe... just in case

"The plane, What can i say about the plane, THE BEST plane i have ever flown, it fly's like a dream. THE BEST 3D aerobat i' ve got my hands on, i have got other 3D models but they cannot touch the CAPICHE 50, i cannot wait for the FUNFLY wing & the BIG brother, i have just started on my second capiche 50, that's how good the plane is."
