For 1998 the Zimmer brothers improved the topless Twister SPS with a revised system for controlling washout.

 

Bautek-Twister-01
Twister SPS
 
Regarded as a great glider, very solid and stable. Hard on hard conditions, but smooth on soft ones. Out of all topless gliders, this is one with the best /easiest handling. At takeoff, there is no slack in the side wires, a big advantage on a windy day without assistance. Control is effortless, without any delay, and well co-ordinated. There were some problems with batten tensioner.
There is a 13m version with less sail (unofficial and unapproved by Bautek), that were made to meet the demand for light pilots.
