Micro FPV Quadcopter 125 | 8.5mm motors and Micro Scisky by phiba

Last crawled date: 3 years ago

This quadcopter frame was inspired by the Micro 105 FPV Quadcopter - 8.5mm Motors, Micro Scisky and the SciSky FC (Quanum PICO) in Parrot Frame, but modelled from scratch.
If you need detailled instructions on how to build such a mini quadcopter beast, I suggest you read punkkills instructions.
Important:
Use the "_1.6mm" stl-files, if you know your printer has troubles with inprint between 1.2 and 1.5 mm layer width! Otherwise, the motor mounts might not be as stable as designed.
Changes:
Wall width increased from 1.5 to 1.6 mm on motor mounts and sides of inner frame.
Stats:

Lightweight: 8 g bottom, 2 g top. My complete setup (see pictures) weighs 43 g. With 750 mah battery it gets to 63 g and ~10 min flight time. 950 mah is also an option to prolong flight time to ~12 min, but you will feel that the quadcopter gets a bit less responsive.


Robust: this frame already survived hard impacts. In fact I was not able to destroy one yet :)


Motor mounts: I desinged to motor mounts to be very robust, so the motors take no damage during crashes or harsh landings.


Micro-Scisky mount: This frame has a built in mount for your Micro-Scisky board to hold it straight in place!

Easy USB access: Rear notch to easily plug in your USB cable for programming.
My setup/what you need:
4x 8.5 mm motors + propellers, e.g. Hubsan 107C parts
Micro-Scisky/Quanum pico flight controller (+ DSM2 compatible radio)
1s LiPo, > 300mah
4x M3 screw, shaft lenght > 18 mm
Optional:
Mini-Camera
5.8 GHz Video Transmitter, e.g. FX MM213TL or TX5813
5.8 GHz antenna
5.8 GHz receiver equipment
Foam rubber, for bottom of quadcopter and camera (see pictures) in case of hard crashes
