This Service Bulletin SB009 requires users to update any Astro Max units from firmware v1.9.1 to v1.9.2 to correct this issue. <strong>If you have an original Astro (non-Max), no action is needed.<\/strong><\/span><\/p>\n<p>&nbsp;<\/p>\n<p><strong>DISCUSSION<\/strong><\/p>\n<ul>\n<li><span style=\"font-weight: 400;\"> Root Cause: An oscillation between the controller and landing gear can exceed the landing detector\u2019s rotation threshold in firmware v1.9.1, preventing detection and thus auto disarming.<\/span><\/li>\n<li><span style=\"font-weight: 400;\"> Fix: Firmware v1.9.2 changes the parameter LNDMC_ROT_MAX from 20\u00b0\/sec to 45\u00b0\/sec, resolving the issue. Over 500 landings on various surfaces (grass, dirt, wood, cardboard, cloth landing pad) at different speeds\/payloads have verified reliable disarming without negative flight impact.<\/span><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p><strong>RECOMMENDATION<\/strong><\/p>\n<p><span style=\"font-weight: 400;\">&#8211;
