Today's guide will be about building an Arducopter, or otherwise known by the locals as "Flying Hedge Trimmer"


My greatest problem with the world of  RC and hobbyists is that there never is a complete guide on doing ANYTHING!

The experience of learning how to build a hexacopter from no knowledge is basically a big scavenger hunt for information. There was always bits and pieces, but never a complete guide for the build log, hardware, AND SOFTWARE (99% of the build).

I'm here to change that issue, so hopefully I can enlighten Instructables with a COMPLETE guide on building a Arducopter!

thanks for your help and quick answer
husamwadi (author)  tvm7771 year ago
I sent a message to your inbox.

Cheers!
i didnt receive anything :) just to make sure you send it, thanks in advance
husamwadi (author)  tvm7771 year ago
whoops, I meant to say that to another person..

anyway, to answer your question, I used pretty much everything on that list.

If you want to save money, build a quad and not a hex, trust me there is really no difference and the hex is WAY over powered.

also if you aren't doing fpv you don't need the:

Boscam RC805 - 5.8Ghz 8 Chn. AV Receiver
L-C Power Filter for FPV A/V Systems

but those were only mentioned in my comments list.

The bulk of the price is going to be the:

frame
motors (x6 or x4)
transmitter
flight controller
and more or less the escs (x4 or x6)

I wouldn't recommend turnigy for motors or escs, but for battery chargers, batteries, and transmitters they are okay.

Don't go cheap on motors or escs. make sure that people have reviewed the brand and that the bearings are known to be smooth.

Thats all then.
quad will be enough for hold a gopro?
husamwadi (author)  tvm7771 year ago
more than enough, a gopro weighs around 900grams.

And if you have 9 inch x 4.5inch props with 920kv motors you get around 900 grams PER MOTOR

900 grams x 4 = 3.6KG!

take the weight of your craft and battery, 1kg + 900 gopro grams =1.9kg

3.6-1.9 = 1700grams=(1.7KG)=(4lbs) left over.

That should be way more than enough.

i dont want to bother you, but maybe could you list what do i need (from your list) to build a quad.
only should i take 4 motors instead of six? thats all?

also, i was wondering, what if i get a 6 motor "skelleton" (idk how to call the 6 arm case) and just use 4 for a while, will my machine fly less? lower? worst? or will be capable of fly with 4 motors instead of six meanwhile i get money for other motors.
husamwadi (author)  tvm7771 year ago
A quad is more than enough to fly with a camera. Heck, I've seen professionals use quadcopters to hold their canon d5 cameras.

Also, go back and READ step 2!!!!

I already included the quadcopter alternative in that step!!!

Thanks!

I'd also recommend buying a spare motor and esc. Also, DON'T BUY TURNIGY AERODRIVE MOTORS, they're trash. Go with NTM or some other manufacturer that is more trusted.
thanks, ill be waiting then :)

***UPDATE***

I finally made the new 3D gimbal. The link is here:

http://grabcad.com/library/gopro-gimbal-v2-5-1

A
lso, I found some really cool brushless motor gimbals (WAY SMOOTHER) 3D printed frames:

http://grabcad.com/library/brushless-gopro-gimbal-v2-1

http://grabcad.com/library/brushless-gopro-gimbal-v1-1

Is there a controller I could buy at a fairly reasonable price that would not require as much modification? (I mainly want telemetry, failsafe, return to start)

How long did the whole system take to build?

WesleyK1 made it!4 months ago

Hi. I built a 450 (I think) using the Multiwii Pro and this guide helped greatly. I got my first flight in today! However, I have one more bit of tuning I need to do that I can't find information on, that is, sensitivity to control.

I skipped the PID stuff because am using Megapirate and heard elsewhere the defaults usually work. However, it did oscillate side to side violently while in the air, so I eventually brought the values down and that has stopped. However, the flight is still way to responsive for a beginner. My neighbor used a Naza and pretty much anyone could pick it up and fly it, it's very stable and "beginner" responsive. Is that PID still or Tx adjustments? Attaching current PID values, suggestions to make it fly more like a Naza for now? I built a cage to do the fine PID tuning, but it seems to me that's to get the most responsive craft possible, I'm not ready for that just yet. ;)

Thanks!

What is the flight time?

Hey, i was planning to buy the APM 2.5 just for the mission planner and the gps points control, i didn't know that MultiWii can be controlled by the same software, the difference in the prices is huge here in brazil, but the gps points feature is essential to me, have you tested this function? I don't have any experience building drones, the APM really worth the price? Nice instructable, thanks in advance.

husamwadi (author)  roquefsd6 months ago

Yep, the gps works fine. Its dead accurate.

The "S" doesn't stand for "cells", it stands for "serial"
So a 3s1p-LiPo has 3 Cells in Serial (3X3.7V) and 0 Cell in parallel connected. you could also get an 3s2p, wich has double capacity, because it has 3 Cell in Serial and 2 Cells in parallel.

husamwadi (author)  skulk6 months ago

Good catch, ill change that!

Great Tutorial, I am wondering if this AC adapter will work with the accucell charger?

husamwadi (author)  carter.doud6 months ago

It should work fine. Just keep it at 15V

Great guide... I'm making a quadcopter on your project, but I don't find the Gimbal V.2.5 project on Grabcad anymore (Page not found).

Can u send me the file?

thank you

How is the wiring on a Quad+ ? I'm tottaly noob, have some problems,on how to set my 9XR pro up properly, but if you can help me with correct wiring i'll be more than happy:) have a nice day.

theargha8 months ago

how to connect the escs, i mean the wire alignment, if i use the turnigy multistar ones?

Hi

I am searching two days now to find Frsky D6fr 6 channel receiver but no luck. Everywhere i looked is out or stock so i am wondering if there is a better one that i can buy or similar one that work two becuase i have stuked .

Thanks

husamwadi (author)  duran11 year ago
You dont have to go with the D6fr, you can go with the D8

http://www.ebay.com/sch/i.html?_odkw=frsky&_osacat=0&_from=R40&LH_PrefLoc=3&_trksid=p2045573.m570.l1313.TR11.TRC1.A0.H0.Xfrsky+combo&_nkw=frsky+combo&_sacat=0

http://www.ebay.com/itm/FrSky-DJT-D8R-2-4G-2-WAY-combo-with-Telemetry-For-JR-PCM10IIS-9XII-8103-/271093959263?pt=Radio_Control_Parts_Accessories&hash=item3f1e758a5f

Plus, I really felt limited with 6 channels, I would advise 8 anyway (only like 10 dollars, 5 pounds, more)

Nice so i i buy the second link that is a combo i dont need the frsky DHT DIY 2.4ghz AACST? Also can i ask you if i need both right hand and left hand proppels ? or it is the same ?

Thnaks !!

bygreencn1 year ago
perfect tutorial.thanks

For future reference, Lipo battery cells are wired in series. So the S in 3s signifies 3 cells in series, or 3 series. Also thanks for the info about the multiwii pro and multirotors in general. Great Project

How much extra weight can raise?
Thank you very much for the guide! :)
It's done!
It's finally finished!
Following this guide I have assembled me a hexacopter!
Here is my roadmap in pictures https://www.facebook.com/media/set/?set=a.504435556297592.1073741825.100001934556610&type=3

However, much to my despair, on the first test flight I discovered that it doesn't want to fly, it wants to spin out of control to any direction it so pleases :(
The spinning happens with no yaw input, in fact the yaw input seems to do nothing even though the radio monitor on the mission planner clearly shows yaw input is happening. Pitch and roll inputs works as expected

Tried to research possible causes and the ones that showed up was the motor booms being too flexible or not in the same plane. This is definitely not the case with the HAL frame.

The changes I made on my hardware is that I'm using the APM 2.6 board, ublox GPS+Compass and AR6210 RX and Devo 8s running deviation firmware as TX

PIDs are not tuned yet so I'm really really HOPING that is the problem.

Here you can see how my electronics are set up, maybe the ublox is not high enough?

husamwadi (author)  DantHimself1 year ago
Awesome! I looked at your pictures and you have a clean setup.

I have a couple of questions just to center down the problem.

Can you plug in the hexacopter via usb (get a long cable) and connect it to your computer.

Boot up mission planner, make sure your remote is on (but keep the hex disarmed for now) and go to the radio setup page.

move the throttle stick and pitch/yaw around. Find the channel that yaw is on and see if it is jittery. If it is smooth and responds like you would expect it, then the problem isn't with the controller.

go to the Failsafe-Arm/Disarm tab. Make sure you go to a room that has space, and put your foot on the hexacopter (to keep it from flying off). Arm the hex, and SLOWLY pull up the throttle (NEVER GO FULL THROTTLE ) until the motors start spinning, then move the pitch/yaw around and check to see if the bars on the screen start to jitter or act weird.

To be honest, I'm 99% sure it is Calibration, because the same thing happened to me before I calibrated it. Follow the instructions in step 23, tether your hex to a frame of some sort, and calibrate it the same way the guy in the video does it. This may take a couple of hours, but take your time, better to calibrate it tethered, then fly it and crash (which really sucks).

also, have you done the frsky mods to your controller? that'd help me to explain the channel 6 setup.

Keep it up bro!
