During the crash a boom strut broke on an Alta X. This Alta X impacted the ground at 70mph so it was not surprising the strut broke, but it reminded us of how critical this assembly is for the Alta X. We have had no in flight failures of this part but want users to integrate a boom strut check into their normal pre \/ post flight ritual.<\/p>\n<p><a href=\"https:\/\/youtu.be\/8E99kr8nlL0\">Instructions on how to execute the test<\/a><\/p>\n<p><strong>DISCUSSION<\/strong><\/p>\n<p>Some key points to convey regarding this issue:<\/p>\n<ul>\n<li>There have been no in flight failures<\/li>\n<li>The boom struts are critical for flight, so we want to be extra careful with them. They actuate the folding mechanism on the Alta X and hold the motors \/ props in the open position<\/li>\n<\/ul>\n<p><strong>RECOMMENDATION<\/strong><\/p>\n<ol>\n<li>Watch the above video and run this test on your Alta X.
