Stabilized Model Rocket using Arduino: Project Advice

I’ve browsed the Internet and been unable to find anything specifically citing that a rocket designed to be stabilized, NOT guided, is strictly illegal. I have, however, found a handful of projects doing exactly what I have described. There is going to be no telemetry or systems that would enable this rocket to be guided at any target, nor is that my intention. I am planning to launch at a certified launch site, and I will fill out the necessary forms to do so.
