QX 90 Frame

thingiverse

This model suits the original Eachine QX90 micro FPV racing quadcopter, with a camera modification I got some inspirations from the FireFlo v3 by SirQuentin, and the orientable camera mount of the Eachine Falcon 250. Print Settings Printer: µDelta Original Rafts: No Supports: Yes Resolution: 0.15 Infill: 17% How I Designed This Electronics improvements: I've separated the VTX part from the camera, I recommend the muteFPV youtube channel tutorial I've add a connector to the camera battery wires to facilitate the assembly. Frame features: I've placed the VTX at the back end of the frame, horizontally, to get its antenna away from propellers and free space on the middle for the flight controller board. The flysky fs-i6 transmitter and its antenna are protected inside the frame itself along with the camera connector. The camera is placed on the front end of the frame, inside a protective and orientable mount. You have a nice field of view cleared from original propellers, motors and arms. You will need a piece of piano wire to make the pivot. I recommend a little bit of glue to seal it properly. I've modeled a cover part to protect all the eletronic on the top of the frame. There are little hook-like shape to hold it in place thanks to rubber band, as shown on the picture above. I like to print it in ABS for material strength. The whole quad rests on a nacelle connected with three shock absorbers, in my case recycled from an old CD-drive but your can use those for camera gimbal. The battery fits inside the nacelle, it's very well anchored and protected. This setup absorb shoks from landings and crashes. I designed propellers guards specifically to this frame to keep it light, but you can use any kind of QX90 guard propellers since I kept the exact original dimensions. Observations This whole setup makes this micro FPV Racing quad crash-proof, low-profil, with comfortable camera field of view. The weight whith my print config is 50g without battery and prop guard.
