Trying out some rocket design ideas eg air brakes by launching a test body with a catapault to get a close-up look at apogee behaviour. The air brakes do not deploy but I get some other good learning value. The tail fins seem to be remarkably effective at low speeds as in too effective. They are pointing the body nose down very soon after apogee which keeps the air flow going past the body from nose to rear which keeps the air brakes closed. I was hoping for some random airflow to catch the air brakes and help them open.
