The Sensor 610 CF5 Topless

The Sensor 610 CF5 is the latest evolution of the topless Sensor. The CF5 like the king posted F5 have 10 main upper surface ribs and 4 carbon lower surface ribs per side. The sail now contains 16 internal fabric profiled shear ribs. New carbon composite leading edge inserts are available as an option for all 610’s. These new leading edge inserts are vacuum bagged in a female airfoil shaped mold, not radius shaped. The weight of the new sail is lighter without sacrificing the numerous reinforcements built into the design.

Named in step with the king posted F series, the topless Sensor began as a CF model in the year 2000. The cam VG system was seen as a better VG system at the time compared to the conventional VG created on the Sensor's in 1982. As it turned out, adapting a similar response flaps system to the cam VG became seemingly an impossible task. With determination and creative brain racking the final flap system on the topless Sensor became a series of small wires and pulleys mounted on the leading edge tubes with the flap wires running under the cross tubes. Recently, new flap wire guides for the crossbar were created with redundant Spectra chords instead of stainless steel strap eyes bonded to the bottom of the spar. The Spectra is lower friction which saves the flap wires from chafing and allows the number one flap wire to be dropped below the crossbar an inch and a half, the depth of the keel tube.

The topless Sensor is the only topless glider on the market with flaps and as a result even with a thinner airfoil maintains a safe and reasonably slow takeoff and landing speed. We can't say enough about the benefits of flaps on a hang glider. Sailplanes and rigid wings have had them for a long time because of their benefits in performance, i.e. soaring performance as well as take-off and landing performance. Flaps are useful not only on takeoff, but for thermaling and climb performance at minimum sink speeds as well as for reducing your glide angle on landing final approach by flying slightly faster at landing pattern speeds. The performance of this latest generation topless Sensor is stunning, yet more can be done in this class of glider; hence, the topless Sensor is currently being redesigned and is targeted for completion by the end of 2008.
