Editor's Note: The Soaring Cafe is delighted to inform our readers of this exciting development by Jonker Sailplanes, announced today (July 20, 2012) on their website.
Jonker Sailplanes is proud to announce the 21m wingspan development of the JS1 Revelation.
The JS1C features the option of interchangeable wingtips that allow either an 18m or 21m wingspan configuration. Instead of the current 1.5m wingtips for the 18m wingspan configuration, new optional 3.0m wingtips can be installed to give a 21m wingspan configuration.
For the higher wing loads and a higher maximum take-off mass of 720kg [1587 lb ] (increased from 600kg), the wing-wingtip junction is redesigned including stronger wing spar caps and thicker wingtip spars. The main structure of the wing is unchanged, as is the fuselage and tail. As from serial number 034, all JS1 Revelations manufactured will be compatible with the optional 21m wingtips.
With the combination of excellent performance, a wide range of available wing loadings and superlative handling, the JS1C-21m is expected to be extremely competitive at the highest level, without the disadvantages of older generation Open Class gliders.
