Introduction: Indoor FPV Drone [Setup,Pattern and 3D Printing]

Hello guys! I'm back with some interesting stuff to testify you. I volition demonstrate the proper way of setting this thing up and I will likewise exist demonstrating my 3D modeling session for the prop guard of this little drone.And If you like this Instructable please click on the middle push and vote. Cheers!

So recently it's been raining here in the Philippines and I can't seem to wing my racing drones during weekends due to field proximity or school work.So I decided to buy a hobby grade micro quad. The QX80 Floureon

This Hobby course micro quad is not your ordinary toy, It does non come with its own transmitter nor receiver. Its basically a kit that may come assembled or not. Good thing I got mine assembled from GearBest. The Kit is 71.32$ and you will need an external receiver to make it work with your transmitter

Package Contents:

1 x QX80 Miicro Quad

2x sets Propeller,

2x iii.7V 600mAh Battery

1x 2s Charging plug [Balancer]

2x Foam Agglutinative tape

1x Prop removing tool

1x Rubber band

Again the kit did not come with a receiver, just skillful thing I have a spare Frsky rx

It'southward an 8ch PPM Frsky Rx module

Pace i: Setup Flying Controller and PIDs

To set things up you lot volition need to charge batteries first, while waiting for it to accuse we need to make certain that our laptop or desktop is able to communicate with flight controller of the micro quad. The flight controller of the quad is based from thr SPF3 Evo Series. And since the micro quad itself is standard you tin can utilise my PID settings for your QX80

Connect y'all flight controller into your computer and brand certain you have internet connection for it to automatically install the driver.

Become to your device manager to make sure that your computer is able to communicate with the FC

I uploaded A quick video that should help you Wink your Flight controller to the latest firmware.

You may or may not need to utilise Zadig.exe in my case I did not need the Zadig.exe which replaces the commuter of a USB device.

Step 2: Soldering

We only demand to solder 3 things in this step the +, -, and rx pivot

So get your soldering iron ready.

There are a few Receiver boards out in that location in the market place and each one has a different protocol to communicate with the flight controller.

In my case, i'k using a Frsky "PPM" protocol. To start this pace we volition need to trim the receiver wires to fit on height of the flight controller.Looking at the motion-picture show in a higher place we volition employ UART2. Solder the wires on the pads of the pcb respectively. and thats just almost it.

Footstep three: FPV Cam and Electronics

The Qx80 kit comes with a decent FPV cam, in fact compared to the FX798T the video quality is non even noticeable. The only divergence between the two is that the FX798T has a switch excursion that enables it to easily switch bands and channels to friction match your FPV goggles. The stock FPV cam has 6 tiny DIP switches and you demand to flip ii to 6 switches to alter channels. At the field or with a grouping of friends flying FPV, upgrading your FPV cam is a reasonable thing but in general, it's not since y'all are just going to fly indoors. Anyhow..... for this instructable I'm going to use my trusty FX798T.

(OPTIONAL) Liquid Tape

Flying indoors does non entirely keep your drone prophylactic, sometimes yous will crash into metallic poles, metal furnitures etc. Yous don't want to run a risk shorting the FPV cam or the flight controller.

So here's what I did

Crashing can brand your FPV cam lean backward and get shorted from the flight controller or the CF plate so apply a generous amount of liquid tape, enough to cover the sensitive parts.

Step iv: Final Touch

Basically information technology comes down to putting the receiver on height of the FC with a Nylon Cable tie

Usually, yous would use the condom band that came with the package just I don't think it'due south enough to hold the battery after a crash.

Pace v: Getting the Dimensions for Designing the Prop Guards

In this footstep, I decided to blueprint my own prop guards since the ones I found in Thingiverse might non be enough to protect my props whenever I will go through tight spaces. So here I decided to 3d model my prop baby-sit in Fusion 360. I'g use solidworks and sketchup but AutoCad was my primary 3d modeling software back in class school, I just decided to use Fusion 360 for my 3d printing entry.

Ideally, my mode of designing stuff is past outset 3d modeling the exact model to have that sure accessory,but in this example, the micro drone was only besides easy to get the plumbing equipment right.

Basically, I just need to go the exact altitude from centre motor to centre motor. I know that information technology says QX80 equally in 80mm merely that is merely an judge value.

This will too big role for designing the guard

Stride half-dozen: Fusion 360

Instead of making more steps I decided to brand a video of how I did it.

Since 3D printers out there have different calibrations like the 10 and Y offset, I propose resizing the STL file by 1 to 2% then merely making the motor holes slightly bigger using a drill flake to trim the insides.

Step 7: 3D Press

I printed mine using my Flashforge pro

ABS Filament 1.75mm

100%infill

.2mm layer meridian

print speed 60mm/sec

The holes on the 3d printed office will non come out perfectly so you might need to make the holes bigger by trimming the inside bore using a drill with a 6-8mm dia. drillbit

Step eight: RX Binding and Channel Checking

There is a push establish on the Rx to bind it with the radio like the Taranis or 9XR you lot must first ready your Controller into bind way. And so once the controller starts beeping prepare the battery of the drone while pressing the button on the Rx module connect the battery proceed belongings the button for effectually 3-v seconds and your Quad is bound to your controller.

Double check your Controller setting and brand sure the channels are properly arranged.

Pace 9: Props Off! Check Tx Rx Com

Double check the Radio communication through your Estimator

Move the sticks on your controller and run into if it follows the movements on the brandish sometimes y'all volition have to invert the stick command

Step 10: Maiden Flying

Brand information technology hover using Bending mode and make sure the stick commands feel good and crisp. The Pitch and Whorl should follow your command and if the quad feels too fast or likewise slow connect it to your computer and get to the PID settings to decrease or increase the rates

Step xi: Have Fun

Fly safely and call up to remove the prop guards whenever you fly outdoors
