Freefly has initiated an internal investigation to determine the root cause of this issue.<\/p>\n<p><strong>DISCUSSION<\/strong><\/p>\n<p class=\"p1\">Some key points to convey regarding this issue:<\/p>\n<ul>\n<li>\n<p class=\"p1\">Motor 1 is always the motor that does not start.<\/p>\n<\/li>\n<li>\n<p class=\"p1\">A reboot of the machine has cleared the issue so that normal operation can continue.<\/p>\n<\/li>\n<li>\n<p class=\"p1\">Throttling up the Alta X without motor 1 starting can cause a tip over.<\/p>\n<\/li>\n<li>\n<p class=\"p1\">We have received no report of motor failure in flight, the failure mode appears to only exist upon startup. Once a motor is spinning there is no evidence that the issue can occur.<\/p>\n<\/li>\n<\/ul>\n<p><strong>RECOMMENDATION<\/strong><\/p>\n<ol>\n<li>Always visually confirm motor 1 is spinning prior to liftoff<\/li>\n<li>Always perform an attitude control flight check prior to takeoff (<a href=\"https:\/\/www.youtube.com\/watch?v=8DSaI8mbxS4&amp;feature=youtu.be&amp;t=345\">demonstrated here<\/a>)<\/li>\n<li>In case of a motor 1 failure to start, disconnect Alta X flight batteries and reboot machine\n<ul>\n<li>Please file a ticket with customer support so we can investigate and track this issue<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n<p class=\"p1\">Freefly will be issuing follow on updates as our investigation unfolds.<\/p>\n<p><strong>See attached PDF for full details<\/strong><\/p>\n","protected":false},"template":"","class_list":["post-34935","kb_article","type-kb_article","status-publish","hentry","support_category-alta-x","support_category-alta-x-service-bulletins"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v24.7 (Yoast SEO v26.0) - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>SB001 Alta X - Motor 1 start failure (1\/17\/20)(Obsolete) - Freefly Systems<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/www.freeflysystems.com\/knowledge-base\/sb001-alta-x-motor-1-start-failure-1-17-20\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"SB001 Alta X - Motor 1 start failure (1\/17\/20)(Obsolete)\" \/>\n<meta property=\"og:description\" content=\"&gt; SUPERSEDED BY SB002 Alta X \u2013 Intermittent Motor Start Failure\u00a0on 2\/17\/2020 &lt;\u00a0 &#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212; Date Released: Jan 17 2020 Effectivity: All Alta X INTRODUCTION This service bulletin is being issued to alert all Alta X pilots of an intermittent failure of Motor 1 upon initial startup.
