I've been thinking about building a HPR Falcon Heavy rocket. I would like to make it somewhat realistic to the real rocket in that it will separate the boosters from the main rocket. I'm pretty sure I can use the a MissileWorks RRC3 to signal the aux output to fire X seconds after launch. But what do I do with that signal. I thought about exploding bolts but then I have the safety factor of those to be concerned about. I thought about some sort of a solenoid that releases a latch. There is a LPR version on here that plans on having them released when the nosecone deploys from the motor ejection. That's ok but not as realistic. Anybody have any other ideas or suggestions for me?
