Actually, you begged for it in the YouTube comments section of every reviewer from Nick Burns to Bardwell. \"Put the O4 in a whoop,\" you typed, ignoring the laws of physics. Well, \u003cstrong\u003eHappymodel\u003c\/strong\u003e actually did it. The \u003cstrong\u003eMobula8 O4\u003c\/strong\u003e is an 85mm scream-machine packing the pristine, high-bitrate goodness of the \u003cstrong\u003eDJI O4 Air Unit\u003c\/strong\u003e into a frame that weighs less than a bag of crisps.
