Ah, the beloved Swirlie. A caffeinated micro quad with a love for darting through trees and micro gates. Here's a few tips for assembly.
Make sure you have the minimum components required.
40mm props of choice
1102/3 10,000kv Motors
Emax Femto or favorite 16x16 or 20x20 hole spacing FC if you're adventurous
20x20 4in1 ESC
Micro RX of choice
VM275T or other AIO vtx.
First step is to start your stack. You can use the included battery pad or use your favorite material. There is no specific orientation. Put the screws through and flip over.
ESC stands and battery strap
Add your ESC stands and battery strap as such. You can do the battery strap later but it's usually easier now.
o ahead and remove wires from your ESC.
Remove wires from ESC
Go ahead and remove wires from your ESC.
Install ESC on frame
You can place the ESC on top of the spacers. The motors pads are meant to go on the spacer. If you have a different ESC spacer version, orientation does not matter.
You can then place the FC spacers on top or wire the motors up first.
Mount your motors and route wires under the FC Spacer. Cut wires to length and solder to appropriate pads on the ESC. Remember to tin all your wires and pads. Make sure one of your
If you shorten the Racerstar motor wires, you can scrap the enamel off the wire with a razor and then tin them.
Tuck those wires
Tuck all your ESC wires under the spacer and to the side.
Install your Femto in the adapter. Make sure to note the USB is resting in the little recess for it.
It should fit all the way in and be flush with the bottom.
Wiring the first channel
Wire the first channel the first center of the three pads. Then wire the + and Ground from your battery connection on the ESC.
Channels 2 through 4
Then wire the correct wire from the 4in1 ESC to each signal pad on the Femto.
Wire in your rx to the correct pads. Note: the XM in the picture is wired to the wrong ports because I'm an idiot and didn't have these awesome instructions during my build.
You can use servo tape to stick the rx on top of your 4in1. This is a good time to bind your rx.
Spacers and antenna routing
Use spacer or a nut to hold down your FC. You can run your rx antenna through an open hole in your FC.
Installing prop guard and vtx
you can stack the prop guard and vtx. The strut bolts into the frame at the end of each motor arm.
Not shown but run your vtx wires through the mount and prop guard. Then wire to your 5v pad on your Femto.
Finishing up the prop guard
Prop guard struts mount as shown. After that drill or cut your props. Remember to setup in betaflight before installing props.
Starting up Betaflight
Betaflight setup is very like any other quad.
There are few things to note. Since the board is turned 45 degrees, you need to setup Yaw 45 degrees off. Once saved, verify in the setup tab that your quad moves correctly when you tilt it.
Setting up ports
If using the recommended FrSky XM with SBUS, you need to first set UART3 Seriel RX in the PORT tab.
Then under the Configuration tab, select RX_SERIAL and below that SBUS.
Continue your radio/switch/motor/esc calibration setup and enjoy!
If you don't know how to do all of that, send me a note on the contact page and I can help you out.
Well here's a bit of additional Betaflight stuff for ya.
Modes! To get you started, I usually like to have a switch assigned to AUX1. You can set it up in Modes to arm the Doinker. Here's I've setup AUX1 to arm the quad and AUX2 to turn Horizon mode on and off. Horizon mode is self stabilizing EXCEPT when you throw the stick past 50%. It's good for indoor flips. You will need to check your transmitter manual or youtube on how to setup a switch to AUX channels. It's fairly straight forward.
To calibrate your ESCs. Follow these steps:
1) TAKE YOUR PROPS OFF!
2) Plug into USB and bring up Betaflight to the Motors tab
3) Click the enable motor control little button
4) MAKE SURE YOUR PROPS ARE REMOVED
5) You can now move the MASTER slider all the way up.
6) Plug in the battery to your Doinker. You should hear some extra beeps and music. When it stops, move the MASTER slider all the way down. It should do more music.
7) Your ESCs are now calibrated!
Congrats! Your Swirlie should be ready for swirls! Take note of your prop orientation when installing. If you have any questions, comments, or just want to shoot me a message, feel free on the contact page or on FB and thanks for the support.
