He would need to adapt the staging mechanism to work with an electric signal. The other possible problem is that the signal happens at apogee, and so the rocket is slowing down to zero upward velocity. With zero velocity, the rocket can start to tip over, so the staging may happen when the rocket is not pointing up anymore.

A better solution for staging is to use the ServoChron Servo Timer. You set it for a time delay after the launch. That would make it such that you can set off the next stage when the rocket was still moving.

I meant for the last stage. I should have formulated it better. I also think it would be silly just to release the parachute and I think it's unnecessary to mesure the height of one stage.

I wonder how difficult it would be to create another program that would detect the acceleration so that as soon as it starts to slow down it would trigger a servo. I can think of a lot of uses for something like that!

I think it wil be as easy as the apogee detect.
Maybe you can even find a (similar) program, so you would only have to change a few things.

that is very nice I gave up on my 2 stage and switched to single
