Eachine BAT QX105 Alternate Frame

thingiverse

This is an upgraded frame design for the Eachine BAT QX105 quadcopter, created to provide a reliable backup after experiencing the fragility of the original carbon fiber frame firsthand. The carbon frame broke on the second day out as expected, prompting me to create this alternative. To minimize camera and flight controller vibration from prop vibrations, I've incorporated anti-vibration dampers into this design. The 60g size from https://goo.gl/CTFx2E was used, but any similar product will work just fine. The frame is specifically designed to support the 10mm brushed motors found on the Eachine QX105, not the smaller 8mm motors commonly used in micro quads. There are two versions of this design: a standard (Std) and a minimal version. The minimal version eliminates the dampers and the bottom-mounted flight controller, instead mounting everything on a single layer. Future updates will include 3mm and 5mm thick versions for each model. The thicker frames provide increased rigidity and strength, making them ideal for camera vibration issues. Keep in mind that the motors and camera are unprotected in these designs, so it's essential to take necessary precautions to protect them. Feedback is welcome on all versions. The standard frame weighs approximately 12.5g with dampers, slightly less than the original carbon fiber frame. The 5mm Minimal version tips the scales at 11.2g. A clip for the Runcam Nano camera has been included in this design to ensure a secure fit. Two "foot" designs are available, each serving as both landing pads and motor protection. Choose one or two designs and install them on your motors for added safety. Future updates will include zip tie cutouts around the motor mounts for the standard frame and a revised camera clip as a separate download. The design draws visual inspiration from SirQuentin's Fireflo V3, found at https://www.thingiverse.com/thing:1152714, but is an entirely original creation. A subtle bat wing design has been incorporated into the arms for aesthetic appeal.
