* Glider Weight is measured from the standard glider.  Some options will decrease glider weight by up to nearly 3kgs.

** Quoted Centre of Gravity measurement is for Mylar sails.

*** 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.
