I have flown my MM a lot since last year and learned a lot. I kinda over built it anticipating that I would fly it for my L2 flight. I passed the test last week so I need to fly something.
With a J motor, the MM will go to over 3000 feet. This is a problem because our site is fairly tight, and I have difficulty walking long distances, let alone climbing trees.
I do have a chute release that I always use to reduce drift, but I have had some funky off-angle launches.
I was inspired by this thread https://www.rocketryforum.com/threads/variable-drag-project.157027/ to add some more drag to limit altitude. This is what I came up with:
I am having them 3D printed now, my thoughts are these will at least triple the drag, move the CP rearward, and limit the flight to around 1000-1500 feet.
My question is, is this a "legal" configuration for a cert flight?
Any other helpful thoughts or comments are welcome.
