Wondering if anyone has ever built a simple remote control ignition system. This would be really simple to do. Just hook a make or break connection between a battery and the wires going to your igniter across a mechanical servo and when it moves the wires together, whoosh. The servo could be any cheap airplane type with a cheap receiver on it. Then you could trigger your rocket from say 1000 feet away or something and see it go skyward. I've been wanting to do this. One caveat is that the receiver should be FM and NOT on 27 mhz so to be more immune to interference and likewise you should have the battery connection point at least 15 feet away as with a normal estes controller launch. That way if the servo prematurely fires you aren't too close to the thing when it goes off. I'd love to do this so I could get good video of my stuff going up by using a tripod etc and the video camera. I could just reach over and push the 'throttle' control on a model airplane transmitter and away it goes!!
