The Aerotech Interlock Launch Controller is a durable device that is used to electronically ignite ALL your model rocket motors from 1/4A size up to a G-size engine. This one has large clips that allow you to hook it up directly to a 12V car battery. That gives you a lot of amperage and gives a hefty jolt of electricity to ignite even the most finicky of igniters. Also, if you can drive your car to the launch site, you can be assured that you have a good battery and not one that is dead. No more will you show up at a launch site and find out that your launch controller battery is dead.
This controller has been designed to prevent accidental launches when given to younger children. It takes two hands to operate, and will not launch unless the safety key is properly inserted.
