(made in 1978)

The Vortex is Chargus' first contribution to the intermediate glider market. The machine, which is supplied in two sizes, follows the Superscorpion deflexerless concept but with the addition of vortex generators. These are little holes cut in the wing tips just behind the leading edge to give a lower stalling speed than normal. Rigging is a bit messy, utilising a difficult to assemble control frame and bolt-on cross booms, like the Mk 1 Superscorpion. Finish is good with lots of attention to details and all tubing is anodised matt black.The performance of the Vortex is good at slow speeds where it really proves its slow flying, slow sink rate ability. The machine however becomes very light in roll at high speeds and will oscilate badly in rough air, particularly if the pilot is inexperienced and is overcorrecting.
