*** 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 RS's.
| Litespeed RS 3.5 | Litespeed RS 4 | |
| Minimum Sink Point: | -0.9m/s @ 40km/h | |
| High Speed Point: | -2.5m/s @ 80k |
These numbers are for a clean harnesses if your harness is boxy, add 0.2m/s to the sink rate at high speed.
