84mm Brushless Micro FPV Quadcopter

thingiverse

I designed this 84mm fpv quadcopter as a trainer. It uses DYS BE1104 7500kv Brushless Motors, EMAX F3 FEMTO Flight Controller (running BetaFlight), DYS 2" 5 Blade Propellers - Set of 4 (2x CW, 2x CCW), Lumenier Mini BLHeli_S 10A 4-in-1 OPTO ESC DSHOT, FrSky XM SBUS Micro Receiver without telemetry and FX798T Camera Combo with Dipole Whip Antenna 5.8GHz 37CH 25mW. Most of these items came from GetFPV. I made all of my connections on the bottom of the flight controller to allow for quick and easy replacement of the flight controller mounting/prop guard section. I was able to use 6mm ss socket head screws for mounting the props and the motors. The camera has a bit of single sided foam tape on the top and bottom to help dampen vibration. The FrSky XM Receiver bracket is mounted to the center of the bottom of the camera bracket with a small drop of super glue. I printed this quad in PLA, and it is holding up nicely. This micro requires the same knowledge to build as a 250mm fpv quad. Actually, it requires finer soldering skills due to the 16X16mm size of the flight controller. It is tiny. Right now I am using a Lumenier 400mah 2S 50C battery and a Tattu 450mah 3S 45C. Both of these batteries came from GetFPV. The 84mm is like a rocket on the 3S. Also, I just added an .stl file for the Femto F3 flight controller mount without the prop guards for those of you who don't want them and added a heavier duty version of the X frame (v1.1). This has turned into one of my favorite quads! Have fun!
