The
Sessanta is a new 1.5m (60") highly aerobatic sports slope soarer from James Hamond. This very pretty model flies as well as it looks, with sweet handling, a great speed envelope and easy landing thanks to its large flaps.
Continuing technical development of previous designs which have gained him a worldwide following, Dr. James Hammond is very pleased to announce the latest entry into the 60-class slope racing sailplane market.
James designed as a modern, sleeker, and higher performing replacement for his first 60 design, the ever-popular Sunbird; one of the best selling all–moulded 60” models ever. Refined in every way and incorporates all of the great things about the original design – and a lot more.
With a single piece wing incorporating completely new and radical wing planform, new aerofoils, new, sleeker and stronger fuselage and the game-changing sine wave spar, the new “Doc J” weapon is extremely quick, yet has all of its older Sunbird brother’s great flying characteristics.

Extension leads required:
4 pcs 20-30 cm ext leads (for receiver)
2 pcs 10-15 cm ext leads (for aileron servos)
2 pcs 25-30 cm ext leads (for flap servos)
