Nano X4 frame

thingiverse

4 inch racing drone frame. > Takes FC with 26.5mm mounting (AIO board) > Arms have 9mm and 12mm motor mounting. > I built 3mm arms and 1.5mm top & bottom plates. > Bottom plate takes press nuts (CNC Madness will install them for $1) I borrowed a couple ideas from Dave_C's Gatehunter frame. The center hole is the same size as his, so you can use those bike thingies if you want. I prefer to fill that hole with a simple piece printed in PETG. It'll work without the centerpiece but I like having extra bit of reinforcement. The canopy should be printed in TPU or PETG. Socks aren't really necessary with a bottom-mounted build, so I'm not sure why I included them. My build is using the BetaFPV 20a AIO flight controller with Emax 1408 motors and the HQ T4 props. If you pick up one of these FC's, get the one with the USB port sticking out the side. You'll need a couple fat rubber bands and a silicone mat (ummagrip) on the bottom to mount the battery. I decided against adding a spot to fit a battery strap on this frame as it would have weakened the mid-section too much for my taste. Once you get used to swapping batteries with rubbers instead of straps, it's just as fast.
