I'm planning to build my first duel deployment rocket. My knowledge of design is based only on what I've read.
A couple of basic questions.
1. Is there a good reason why the initial rogue deployment is not triggered by the ejection charge within the motor (in my case a Cesaroni 29mm or 38mm)? The second stage main parachute being altitude triggered by an electronic charge.
I can only think it is the accuracy of the timing of the initial charge that gives an advantage to an apogee driven charge rather than the motor charge.
2. If I choose to use two electronic charges and drop the motor charge, is it usual to scrape out the Cesaroni motor ejection charge and fill the void with epoxy? I've read this but would appreciate confirmation that this is a tried and tested method.
SO.
