Xevo100 (brushed micro quad) by xeVox

Last crawled date: 3 years ago

The Xevo100 is a tiny beast build around the "sp-racing F3 evo" flight controller. With about 67g it's very light weight, powerfull and a ton of fun to fly! It's perfect for beginners, since the frame is almost indestructable.
You can fly eighter indoors or outdoors, but if you choose to fly indoors take the small triblade props, since the bigger ones are way to strong. If you are new to flying, start learning the basics in Line of Slight flying outdoors, so you get used to the controls. There are also a ton of tutorials on youtube.

To build one for yourself you'll need:
parts from Banggood:
FC: sp-racing F3 evo
motors: 4x 8520 Racerstar brushed motor
A transmitter/reciever combo or just a reciever if you already got a transmitter
65mm biblade props (for outdoor flying only)
45mm triblade props (for indoor or outdoor flying)
AIO FPV Camera: TX01, TX02, TX03, TX04 (I highly recommend the TX04, since the cloverleave antennas break very fast)
9.5mm Buzzer
other parts:
some rubber bands (≥2x)
small M3 machine screws (3x)
tools:
soldering iron
3D printer (obviously...)
PC with betaflight app
Instructions:
1. Assembly

Print the frame using abs or petg filament (pla might work fine, but i think it will soften around the motors, since they tend to get really hot)
if you use abs filament, scale the model by 101%, because abs tends to shrink a lot when cooling down.
use a brim and print the first layer really slowly (~5mm/s)!
Depending on your 3D Printer's accuracy, you may have to widen the holes for the motors. You can use a 8.5mm drill bit, that you rotate by hand


Now you can insert the 4 motors. Looking at the top of the frame they go in like this:
The 2 cw motors (red and blue wire) have to be mounted on the top left and bottom right
The 2 ccw motors (white and black wire) have to be mounted on the top right and bottom left


Put in the rubber band for the battery


Before you mount the FC you should flash the current Firmware using betaflight
solder the bootloader jumperpads
make sure you always close chrome while doing anything in betaflight
open the app and download and install the 2 drivers (there are 2 links on the main page)
restart your PC
open the app and connect the FC via usb
go to the menu point "flash firmware and follow the steps of the screenshot
desolder the boatloader jumperpads


Secure the FC temporarly to the middle of the frame using some double sided sticky tape.


Solder the Motor wires to the Motor Pads on the FC. The ground wires (blue or black) are always facing to the front of the copter.


Solder the reciever wires to Uart 3 (starting from the back: black, red, white... the yellow one can be cut off)


Solder the Buzzer wires (not the Buzzer yet, only the wires, that should be ~20mm long) to the Buzzer pads

Solder the Battery wires
FPV setup:
Depending on which camera you chosed to buy, download the right mount and print it in abs or petg filament with supports. (The Camera also gets really hot, so I would't recommend to use pla)
if you are using abs, scale the part in your slicer by 101%!
push the camera in the mount, you may need to remove a bit of the printed part in order to fit the camera perfectly. Use a hobby knife, but be carefull and wear some safety gloves!
take a rubber band and secure the camera and the reciever to the mount.
Solder the camera wires (eighter to Uart 1 or 2 or the battery pads)
put the mount in place and thread the buzzer wires through the front of the mount, by sliding the FC in dedicated slot.
plug the reciever in
solder the buzzer to the buzzer wires (make sure you got the polarity right!)
screw the mount to the frame, make sure you don't overtighten the screws!
put the buzzer in place
Congratulation, you just finished your build! Now it's time to set up betaflight and bind your transmitter. There are a lot of tutorials already on youtube for doing that.
