NightHawk (Emax) Beefy Arm

thingiverse

I have been using this arm for a significant period of time, and it has withstood even the most severe crashes without sustaining major damage. The integrated spacers and strain-relief components contribute significantly to its durability. Measuring 4.7mm in thickness, the main section of the arm gradually tapers down to 10mm at its base. Notably, a dedicated channel facilitates effortless routing of motor wires. Furthermore, the strain relief effectively minimizes stress concentrations that typically occur near the frame's pinch points. These lightweight arms significantly outperform their thick replacement counterparts made from carbon fiber. Although I have encountered instances where the thinner arms supplied with the frame succumb to damage, my custom-printed arms remain remarkably resilient. Key differences in specifications between stock and printed components are striking: Thin (3mm) carbon fiber arms with spacers weigh a mere 9.6g each Custom-printed arms with integrated spacer and strain-relief measure 14.5g each Thicker (5mm) carbon fiber arms with spacers, on the other hand, tip the scales at 18.7g each In light of these stark weight differences, one might consider investing $50 in a thicker carbon fiber arm. However, this can be effectively countered by opting for the printable alternative, which allows you to customize it in any color at an approximate cost of just 50 cents and save approximately 4g in weight per piece. To print these components successfully, employ the following settings: Print Brand: Solidoodle Printer Model: Solidoodle 2 - Pro Raftless Printing: Support-free Printing: Resolution: 0.2mm Infill Percentage: 100% with a 45-degree angle. Once printed, carefully remove any integrated skirt or brim to optimize performance.
