Hi there,

Juba was one of that era Curare variants, it's aerodynamic modifications were designed by Jussi Salminen and it was flown to 1978 Finnish champion by Esa Eirola (finnish champion on years 1975, 1978, 1999)

Wing was designed specially for snap-rolls and worked quite well...

There is some picture of Esa and Juba on [link=http://www.rcuniverse.com/forum/m_5568774/tm.htm]Pattern Ships from the "Golden Age" [/link]thread , post 23
