First RC build - Hexacopter w/ many calculations ^^


Hey there!

I found this forum after digging down for various sources,  registered to RCGroups and made my thread there, but I thought that it would be great to maybe stay here as well - as both communities are great and really gave me a heck a lot of experience. I suppose I am not the only one who is registered to both? ^^. As with the other forum, here I was able to find a huge block of info - so  I wanted to thank you all!

Here's a little bit of my backstory:

I got interested in drones, like I most people - when the hype started, and a couple of years back my brother gifted me a Syma X5C for Chrsitmas.... now:


One of my friends is also building an Arduino based 250 (his first quad ever) and he's a huge inspiration/help as well. It's really nice to have somebody close-by to share the experience together. My Syma X5C was gifted by my brother (in 2014) and it always gave me joy, so I hope the RC hobby will turn out to be something for me.

My first drone - Syma X5CI recently replaced an engine and got some Turnigy 750mAh batteries for my Syma X5C. It's a good thing I noticed in the forums someone saying that you need to change the poles around. With the batteries coming out of my jean's pocket (in -15C weather) around 13-14 minutes of flying time with everything stripped! Superb!

With the X5C I have the sports/training covered for now, but since I am keen on doing everything, I will probably end up with an another copter later, with an APB or a KK FC to mess around with. For now though, I will be mostly focused on this.


My first project is named 'Bunker' and its goal is the most stable flight possible to capture pro quality video/photo. Since my Sony AS30V seems to be dead (focus is completely lost, I will try to fix it though). It will probably try to lift my Fuji X-E1 EVIL camera (with an 16-50mm lens), or if that seems a tad high in weight for my imaginary budget, I will just get a GoPro - so it will be much lighter.

After all of the consideration I decided that I want an S550, NAZA based Octa. I did not choose an off-the-shelf drone, because I enjoy figuring things out and building them. There are many local ads for ARF drones, I might use some of them for parts. I hope this thread will be helpful for other newbies as well. As I am complete beginner in RC - like I said, it's my 3rd day! So maybe my little contribution would be a nice example - and I will take all the advice I can get here :D

Here is a small brief on what is currently planned:

RC Career Step 0:
Turnigy 9X w/ FrSky

Step 1:

  • Frame: S550 Hexacopter from HobbyKing
  • NAZA /w PMU /w GPS
  • SunnySky X2212 KV980 - I am a tad poor, so this is the best I can buy basically! Hopefully not from BG! 
  • Emax Simonk Series 30A 
  • Rotors 9 or 10 inch (calculating, info in link below)
  • Powered by 3S or 4S (calculating, info in link below)

Step 2:

FPV + Recording equipment

Yesterday I found a local ad with some parts that I needed:

1) iMAX B6AC Dual Power Charger

Since I do not have any proper battery charger, apart from the genius SYMA X5C 'hey let's connect this .. USB KEY into a battery' type of thing I went for this.

I really liked the ergonomics of the device, and since I did not have any other batteries apart from my 1S ones, I took off the plugs off the ends. (TOP TIP: remove the rubber sleeve first... or its much more.. weldable :D, burned a battery..and my hands..and tbh just get a proper adapter - I wont be unplugging the terminals unless I REALLY NEED TO) and connected it using the crocodiles. Charges well and I am feeling much more secure!

Body unit with the Turnigy NANO-TECH 750mAh 3.7V connected

The glorious display of the iMAX B6 is awesome!

2) NAZA Lite

I've got an used NAZA Lite with the PMU/LED in the box, as well as the ultra cool M8N GPS.

I saw a good review here about the GPS location lock speed -

It seems like the chinese GPS blows the stock NAZA GPS out of the water. So I thought it was a good pick to buy it together as a bundle.


2016/01/24 Evening

A little off track: experience with iMAX B6AC and Turnigy 750mAhs. Basically. I cooked one of them. Accidentally left the rubber bit on .. AGAIN.. and when I took off the micro pin to charge it, it welded itself so badly, I just ripped the cables out to explosion in my face. So really, newbies.. and intelligent people, if you're tired, distracted, or not at 100% - don't mess around with batteries. After that I tried to solder the connectors back (this time wearing safety gear) and I couldn't do it, but I was man enough to say - this is dead - just deal with it.

Sadly now only a few pins w/ cables remain as a reminder. RIP battery.

Last night was - forget and push the buy now button night. In the end the part list that was ordered was this:


  • S550 Hexacopter  - bought from HobbyKing international (god help me). They were also too lazy to give me a 'proper' custom declaration value, because it seems I am not a 'gold' (IIRC) member. Even though I ordered 3 packages at the time, they said that its impossible, until the system makes me a member.. So I guess I should prepare to pay taxes.

  • SunnySky X2212 KV980 - bought from GoodLuckBuy, here I also made a mistake of buying all of them together, instead of 1 by 1, because they refused to ship them indipendently. I hope I wont get taxes to death as well here. It seems BangGood are all fakes, so I am happy that I found info to buy from GLB only.

  • NAZA M-Lite w/ M8N GPS and Naza PMU - bought this from a local hobbyist, he was very nice. Forgot to add one of the channel cables, so I will go to his work and pick it up today.

  • Afro Slim 20A ESC - HobbyKing. in the end, I found these gems. A bit cheaper, much lighter. Also they say that they have 2x15A parts, and it's okay to have them on the edge. Since the engines will go max 18A.. I should be okay, did not want to get the 30A for the weight.

  • GWS Style Slowfly 9x4.7 Green -  HobbyKing.  (bought 4 of each, if I understand - this was a mistake because they're gonna snap like a bitch? Need to stockpile them? :D) - I don't understand anything about propellers apart from their diameter and pitch. So I chose to go with these for now. 

    Should I get carbon fiber ones? What about the wood ones? Those look cool ^_^...
    Also need to learn about balancing. Really badly.

  • Turnigy 20C 5000mAh 3S -  HobbyKing.  it was this vs MultiStar vs ZIPPY FlightMax, so I decided to go with Turnigy - because thats what I use now, I am happy with it. 


  • Afro USB tool
  • iMAX B6AC Dual Power

Waiting for auctions, to get the last parts for now.

Updated the list with all of the prices: Item & Calculations sheet



* Auctions 

* Picking up NAZA cable from the forgetful dealer.

* Getting a 9V for my multimeter and checking if my power adapter is okay.
* Connecting Naza to constant power.

I suppose a 12V/1A power adapter is okay to connect to NAZA? Because I am waiting for my batteries.

Dear friends,

I want to make a drone for taking aerial pictures of agricultural fields as a part of my project. From my literature review I found that a hexacopter or octacopter is suitable. Thus I decided to make a hexacopter. The average weight of the hexacopter with the camera is about 2700g to 3000g. Thus I want your help in selecting the suitable components. I am in Eritrea and cannot keep changing the product and do trial and error due to the fact that materials are not available in the country and when imported are very costly, thus cannot afford changing and doing the trial. I am new to the drones and have literally no pilot experience. please help me in selecting the most suitable components.  If you are suggesting any new components other than the ones listed by me, it will be a great help if you can give the link to purchase. This is due to the fact that internet connectivity is very poor here. It will also be a great help if you can sent your suggestions to my email (  as gmail opens here very fast compared to the others.
