That’s the route I took, but there are many complex details to make dual deployment work successfully.I just ordered an Av-bay kit and payload tube to convert my Zephyr to dual deploy. Cant wait to stuff some big motors in it.
The amount and the packing of the BP deployment charges, and the shock cord lengths and configurations, and packing of the shock cords, chute protectors, and parachutes are extremely complex.
I also had redundant drogue and main chute ejection systems, each with different parameters.
And I did about a dozen ground tests for both the drogue and main chutes that I made high speed videos of to determine whether each deployment was working properly. The remote Bluetooth testing of the Eggtimer 6-channel Proton, with its backup drogue and main deployment modes, each with independent parameters worked quite well. Test, test, test! It’s safer to learn on the ground than when you can make changes without having to replace a crashed rocket.
I also found that an Altimeter3 mounted on the nosecone was extremely useful during testing for measuring the ejection charge acceleration to determine the optimal BP amount. The nosecone-mounted Altimeter3 was essential during the launch for collecting launch data, and using it to refine the RockSim simulation parameters.
