“The majority of my aircraft are scratch built. Weighing over 250g. I use my craft to teach flight, electronics, and programming to youth. These proposed requirements scoped to impact the hobby would do so at a determent to the youth that i have and could have a positive impact with, not only in education, but also in community. I have major concerns to what air-craft would be allowed to fly, where they would be allowed to fly, and what parts i might be limited to use as I design and make my own parts. https://www.thingiverse.com/thing:1096211 https://www.thingiverse.com/thing:1663329 https://www.thingiverse.com/thing:1474936”
