Most small model rocket motors are single-use engines, with cardboard bodies and lightweight moulded ceramic nozzles, ranging in impulse class from fractional A to E. These motors are tested and certified by the National Association of Rocketry, The motors come in standardized sizes: 1/2A, A, B, C, D and E. The diameter of each size is fractional A 13 and 18 mm; A, B and C 18 mm; and C, D and E 24mm. Because of the hot gases being released on ignition it is paramount that the rocket body is packed between the motor and the parachute, with heat resistant recovery wadding before launch. Because of the fragile nature of the coated igniters we can supply these as spare packs of six.
We regret that current security and carriage regulations do not allow us to deliver rocket motors or igniters to addresses outside of the United Kingdom.
