The 4-arm <strong>True-X<\/strong> layout is designed for heavy-duty FPV platforms where structural rigidity, load capacity, and secure mounting of heavy components are essential.<\/p>\n<p data-path-to-node=\"3\">The frame for <strong>15-inch propeller drones<\/strong> is manufactured from carbon fiber with directional fibers and features an arm thickness of <strong>10 mm<\/strong>. This robust power profile is engineered for elevated stresses from large props and high-torque motors; massive arms resist flexing and maintain geometry even during intense operations.<\/p>\n<p data-path-to-node=\"4\">The Heavy Line F415 frame is tailored for heavy FPV builds: payload carriers up to 5 kg or endurance platforms intended for long loitering times. Dimensions of <strong>460 \u00d7 460 \u00d7 65 mm<\/strong> allow placement of dual 8S3P battery packs, power systems, and auxiliary equipment. The frame weight is <strong>700 g<\/strong>, an important factor to consider when matching build components to the target specifications.<\/p>\n<p data-path-to-node=\"5\">Flight stack mounting supports <strong>30.5 \u00d7 30.5 mm<\/strong> (M3) patterns, while additional <strong>20 \u00d7 20 mm<\/strong> slots expand mounting options for electronics. The quadcopter frame is compatible with <strong>42xx size motors<\/strong>. The motor mounting bolt circle diameter is <strong>\u00d825\u2013\u00d832 mm<\/strong>, secured using four M4 screws.<\/p>\n<h3 style=\"margin: 0 0 8px 0; line-height: 1.2;\"><strong style=\"font-size: 16px;\">Package Includes:<\/strong><\/h3>\n<ul>\n<li data-path-to-node=\"4,0,0\">Top plate IP27 F415-F421, 3 mm \u2014 1 pc.<\/li>\n<li data-path-to-node=\"4,1,0\">Bottom plate IP27 F415-F421, 3 mm \u2014 1 pc.<\/li>\n<li data-path-to-node=\"4,2,0\">Cover plate F415, 3 mm \u2014 1 pc.<\/li>\n<li data-path-to-node=\"4,3,0\">Bottom X-brace F415, 4 mm (with press nuts) \u2014 1 pc.<\/li>\n<li data-path-to-node=\"4,4,0\">Top X-brace F415, 4 mm (with press nuts) \u2014 1 pc.<\/li>\n<li data-path-to-node=\"4,5,0\">X-brace F415, 4 mm \u2014 2 pcs.<\/li>\n<li data-path-to-node=\"4,6,0\">Arm F415 15\u2033, 10 mm \u2014 4 pcs.<\/li>\n<li data-path-to-node=\"4,7,0\">Plate with press nut, 3 mm \u2014 4 pcs.<\/li>\n<li data-local-id=\"de91db91e812\" data-prosemirror-content-type=\"node\" data-prosemirror-node-name=\"paragraph\" data-prosemirror-node-block=\"true\">M3\u00d78 Flat head screw \u2014 10 pcs.<\/li>\n<li data-local-id=\"3523c61b72c2\" data-prosemirror-content-type=\"node\" data-prosemirror-node-name=\"paragraph\" data-prosemirror-node-block=\"true\">M3\u00d78 Button head screw \u2014 4 pcs.<\/li>\n<li data-path-to-node=\"4,10,0\">M3\u00d710 Button head screw \u2014 4 pcs.<\/li>\n<li data-path-to-node=\"4,11,0\">M3\u00d725 Socket head cap screw \u2014 1 pc.<\/li>\n<li data-path-to-node=\"4,12,0\">M3\u00d730 Socket head cap screw \u2014 4 pcs.<\/li>\n<li data-path-to-node=\"4,13,0\">M4\u00d730 Socket head cap screw \u2014 4 pcs.<\/li>\n<li data-path-to-node=\"4,14,0\">M4\u00d725 Socket head cap screw \u2014 20 pcs.<\/li>\n<li data-path-to-node=\"4,15,0\">M3\u00d750 Socket head cap screw \u2014 4 pcs.<\/li>\n<li data-path-to-node=\"4,16,0\">M4\u00d714 Socket head cap screw \u2014 16 pcs.<\/li>\n<li data-path-to-node=\"4,17,0\">M2.5\u00d76 Button head screw \u2014 2 pcs.<\/li>\n<li data-path-to-node=\"4,18,0\">M2\u00d74 Button head screw \u2014 4 pcs.<\/li>\n<li data-path-to-node=\"4,19,0\">M2\u00d78 Button head screw \u2014 2 pcs.<\/li>\n<li data-path-to-node=\"4,20,0\">M3\u00d720 Button head screw \u2014 2 pcs.<\/li>\n<li data-path-to-node=\"4,21,0\">M3 DIN 934 Nylon lock nut \u2014 12 pcs.<\/li>\n<li data-path-to-node=\"4,22,0\">DIN 934 Metal nut \u2014 2 pcs.<\/li>\n<li data-path-to-node=\"4,23,0\">Black aluminum standoff, 20 mm \u2014 4 pcs.<\/li>\n<li data-path-to-node=\"4,24,0\">Black aluminum standoff, 32 mm \u2014 6 pcs.<\/li>\n<li data-path-to-node=\"4,25,0\">Video Transmitter (VTX) Bracket \u2014 1 pc.<\/li>\n<li data-path-to-node=\"4,26,0\">Quick-release VTX Mount \u2014 1 pc.<\/li>\n<li data-path-to-node=\"4,27,0\">Left Camera Front Standoff \u2014 1 pc.<\/li>\n<li data-path-to-node=\"4,28,0\">Right Camera Front Standoff \u2014 1 pc.<\/li>\n<li data-path-to-node=\"4,29,0\">Left Camera Damper \u2014 1 pc.<\/li>\n<li data-path-to-node=\"4,30,0\">Right Camera Damper \u2014 1 pc.<\/li>\n<li data-path-to-node=\"4,31,0\">Rubber Pad Set \u2014 1 set<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Heavy Line F415 carbon fiber frame designed for large-scale 15-inch FPV drone builds.
