National Safety Month
June is National Safety Month, and it’s a great time of the year to remind yourself of the best safety practices in our hobby. AMA has a wide range of safety-based resources, including the AMA Safety Program Handbook, which can be found at www.modelaircraft.org/sites/default/files/documents/100.pdf.
For a compilation of AMA safety videos, visit the AMA YouTube channel at www.youtube.com/@modelaircraft. Various safety topics, such as battery care, night operations, drone safety, and much more, are all covered in a great 22-video safety playlist at bit.ly/3Eo48qR.

Model Aviation Magazine Celebrates 50 Years!
Model Aviation, the flagship magazine of AMA, is celebrating its 50th year of publication in its current form! The first issue was published in July 1975. Since then, it has been a monthly publication and key benefit for members. The magazine has evolved with technological advances and industry changes to stay current.
Throughout 2025, we are celebrating this milestone in all of AMA’s media channels. Perhaps you have a story to tell concerning Model Aviation magazine, or maybe a moment in time when the magazine inspired you in some way. Submit your story to media@modelaviation.com. It might be shared with the membership in future communications.
