International Thermal Sailor

The International Thermal Sailor (I.T.S.) is a competition parachute duration model rocket that meets the criteria of the F.A.I. (Fédération Aéronautique International: the world governing body for air sports, aeronautics and astronautics world records). The international rules for parachute duration models (S3) require the rocket be a minimum of 500mm long, and that for half of that length, it has a diameter of 40mm. The I.T.S. kit comes with a lightweight body tube, a super-huge parachute, and has an aerodynamic shape. Get ready to chase this rocket a long way, as it sails effortlessly on air currents. Assembly is required. To fly this, you'll also need a launch pad set and 13mm diameter model rocket engines.
