* Glider Weight is measured from the standard glider. Some options will decrease glider weight by up to 2kgs.
** Quoted Centre of Gravity measurement is for Mylar sails. For Dacron sails, subtract 10mm.
*** Measured at Optimal Pilot Weight
Features
- Light predictable handling for easy control in heavy Traffic.
- Reduced airframe weight.
- A tight wrinkle free sail with minium twist providing superior glide performance.
- Improved pitch stability and tumble resistance providing uncompromised safety.
- A spar utilising pre-impregnated carbon fibre to ensure the best possible strength and structural consistency.
Polar
The below data represents the approximate polar setting for various Litespeed S's.
| Litespeed S 3 | Litespeed S 3.5 | Litespeed S 4 | Litespeed S 4.5 | Litespeed S 5 | |
| Minimum Sink Point: | -0.9m/s @ 40km/h | -0.9m/s @ 37km/h | |||
| High Speed Point: | -2.5m/s @ 80km/h | -2m/s @ 74km/h |
These numbers are for a clean harness... if your harness is boxy, add 0.2m/s to the sink rate at high speed.
