A propos de l'attache magnétique je viens de lire ce message dans "RigidWing".
Yes, I've made a "boom mount" using the neodydium magnets and it works well and does not require any holes or modification to the Atos. Make sure you thether it somehow to the wing or rib just in case the magnetic mounts break loose. That happened to me this fall when I was rocked by an incredible thermal - thought I was impacted by another glider! I saw my boom and camera break loose and fall 6,000 ft into a corn field - never to be recovered
