Multirotor part list check

[Jackster]

Hi all

Coming into the nice time of year and I am off to Uni next year for film and cinema production.

I would really like to get into aerial photo/videography as it will help a lot in the course.



So I want to start small and cheapish to get me going and then when I feel good about it ill get a bigger one later.

Here is the list of parts I am thinking of getting, id like people's input on if I have the correct parts and if there is a better part within the price range of a total of about £160 (this includes transmitter and battery).


I saw a lot of people build nice kits using this Q450 Glass Fiber Quadcopter Frame 450mm - Integrated PCB
Also gives me a good platform for a camera.
$15 400g

For the brains I saw this is quite a good one for being able to easily set things and get started
Hobbyking KK2.1.5 Multi-rotor LCD Flight Control Board With 6050MPU And Atmel 644PA
$30 55g

Motors I am not 100% sure on, I saw a few guides on forums suggest between 900-1200kv so I went for D2822/17 Brushless Outrunner 1100kv

$40 ~160g


As for the ESCs I was also not %100 on these too. I heard that these "Afro 20Amp" ones had some firmware made for multirotor
$50 for 4 ~120g

Receiver I was told you only need a 4 channel, but I have gone for 6 incase I want the option to have a remote shutter/other function. Went for cheap on this one OrangeRx R615 Spektrum/JR DSM2 Compatible 6Ch 2.4Ghz Receiver
$7 40g

Props I don't know too much about, these 10x4.5 SF Props 2pc CW 2 pc CCW look nice
$5 ~60g


For the battery I want something that will give me a good flight time for the price.
From looking at topics something around 3000-3500 will give a good flight time of 20-25 mins?
I am guessing a Turnigy 3600mAh 3S 30C Lipo Pack would be better and this one was the lightest at that capacity.
$26 320g


So that is about it for the main stuff.
There is a few things like a low voltage alarm, and Male to Male Servo Lead adding $8 and ~20g



I will also need a transmitter as this will be my first proper RC (used to fly cheap foam kits) so I am thinking of getting the OrangeRx T-SIX 2.4GHz DSM2 6CH $65

Also going to need to charge the battery, happy to go with a cheap unit like the HobbyKing E4 Balance Charger.
$14
Though I guess if I am willing to pay $14, $5 more would not be too bad to get the HobbyKing ECO6 50W 5A Balancer/Charger
for $19



So that is the whole list, I know a few things are out of stock on the UK warehouse where I would be getting them, I guess this is due to people starting to stock up for summer?

Total weight for the copter is around 1175g and total cost for the copter is $180

With the transmitter and charger it is a total of about $266 and equals about £159 so in my budget (did not include shipping though).


Any suggestions for better components? is 1.2kg okay for this setup?

Thank you!

The kk2.0 board has been replaced by the kk2.1.5
Those escs are fine. When you buy the orange transmitter I think it comes with a receiver

I'd suggest buying a whole bunch of props, you're likely to break them
On that note, have you thought about building the quad yourself? If you use wooden booms it makes it a ton easier and cheaper to repair when you crash it.

 

[Cyberdactyl]

That all looks good Jack. That is standard fare for a basic quad. If I were to suggest anything different, I would break that $27 in half by buying two 3S 2200 30C packs instead of that 3600. It'll make the quad lighter, and you'll get much more satisfaction with two batteries.

Ditto on the props! When you crash and break a propeller and everything else is good, it is torturous waiting for propellers to arrive. Buy at LEAST 3 sets for your quad.

 

[Jackster]

Ah yes was planning to have more than one set, was thinking of getting a set of each colour :3

Updated OP with the KK2.1.5

I take it this is better than the one before? Less bugs right?

 

[ikem]

I just ordered 28 props for my 2 tricopters to go along with the ~16 that i have. Always good to have extra.

I am going to test the added flight time with 2 - 3s 2200 vs 1 later this week. I hope it is better than running 1 3s 4400.

 

[Mustang7302]

The selection you've made isn't bad as far as getting into the air. It will be a bit heavy though, north of a Kilo, and prone to damage in crashes. You will crash. So the lighter you can make the craft with reasonable power the more it will be able to endure moderate bumps along the way. Even with the larger battery, you'll only see upwards of 15 minutes or so of flight; which in it self is plenty long for pilot fatigue.

 

[Jackster]

Well I hope not to crash too much

Going to be flying over grass most of the time so I hope the weight is not too bad crashing into that surface.


I take it the weight is going to help stabilise any video too?

 

[Jackster]

Think ill have to go with the Turnigy 9X, Orange is out of stock but get more channels with this one plus a receiver so win win really.

It is also not in stock in the UK warehouse but should soon be in the EU one.

[edit] Meh ill get the Orange, no messing with modules and having to use Lipos when the Orange can use AAs.

 

[Jackster]

What is better for beginner, high, mid or low Kv? (speed or torque or middle?)

I have heard higher RPM = better for video due to "less vibrations". That correct?

 

[crlock]

oh jack, you will find out that physics is a biatch Think of it, a mass of one kilo free falling at roughly 10 meters per second, it will not be pretty i'll tell you that ;D even hiting the grass at that speed will hurt your pup.

 

[cranialrectosis]

For newbies, faster, lighter motors mean less hassle with vibration, quicker response (means you dont have to think quite so far ahead), less inertia when you crash and less cost when you break one.

Be sure to use Simon K for your ESCs to leverage the speed of your motors.

 

[Jackster]

Still not sure on what motors to go for.

Can anyone recommend some sub $15 ones that are good for low vibrations/newb?

 

[Cyberdactyl]

I've had great luck with Rctimer motors Jack.

Orders from them come in a respectable time of around 18 days for a Chinese source. Their customer service is good. One of my orders was incorrect recently, I emailed them a pic of the mail envelope and contents and was refunded the next day.

Many of the motors are free shipping as well.

The A2830 line has a nice KV selection.

Awesome ill take a look!



Oh and another question, props...

Not sure what to match with lets say the 1300kv?

 

[Cyberdactyl]

0847 (8") or 0947 (9") will be a common two that will work well.

 

[Jackster]

0847 (8") or 0947 (9") will be a common two that will work well.

Not sure on the 4 digit number there, does the "0847" mean 8x4.7"?

If so only found 8x4.5 and 10x4.7 :3

 

[Cyberdactyl]

Not sure on the 4 digit number there, does the "0847" mean 8x4.7"?

Yes, 8" with a 4.7" pitch.

10" is pushing that 1300KV I'm afraid. The motor would run warm to very warm.

 

[Jackster]

Was not planning on the 10" ones

Could you link me to a set that you'd recommend on either Rctimer or HK please?

 

[Mustang7302]

Didn't find 9x4.7" props in CW and CCW pairs like I prefer; so piece together your own pairs.

Front Left Prop: Green 9047SF CW
Front Right Prop: Green 9047SF CCW
Back Right Prop: Black 9047SF CW
Back Left Prop: Black 9047SF CCW

Each color/direction combo comes with four props each; order a minimum of two sets of each, preferably three sets.
