The best solution for large motors ignition.

The SierraFire 120 are designed to be used with large reloadable rocket motors, from 54 mm up to 98 mm. Their pyro head ignites at extremely high temperature producing a small ball of fire and sparks which can ignite even the most stubborn of the motors.
The wires are thicker than other Sierrafire ignitors, and longer too. For this, the Sierrafire 120 are stiffer, making it easier to insert them into the motor and stay upright before ignition.

A 12 volt launch controller is required.

When to use these igniters?

Anytime you need to start a K, L  or M motor. The head of these igniters is bigger than others and makes a larger ball of fire. For M motors you may want to tie some slices of Aerotech Blue Thunder propellant to the ignitor head to increase the flame even more.

They can be used in clusters but we do not recommend to ignite more than three motors at once.
