Chargus is known in the British hang gliding world and was one of the first such manufacturers to see the potential of power. The Robin engined T250, usually flown with the Vortex 120 wing, is the company’s only single seat trike unit. The company concentrated on getting the maximum thrust out of the single cylinder engine, by using a toothed-belt reduction drive and a three bladed propeller. The Vortex wing is a single-surface design.
