Quiery:Imported Flysky fsi6 ia6b Rx Tx from Banggood.

I am using 1045/1045R props.

I am using 1045/1045R props.

The max. Prop size which you can safely use on 2200kv motors is 6inch. Anything exceeding this can drastically increase the current draw and burn the speed controllers.

@pinak28,
Kiran rc's post is the first correct advice on this thread.

Looks like you got the frame, motors, ESCs, props, battery as individual items and not a matched set.

There are many issues involved.
1. What is the all up weight with battery?
2. Is your battery 2s or 3s?
3. Pl provide whatever details you have about the motors, esp brand, max watts, max amps (60 sec), max amps (continuous). Kv you said is 2200.

Note that the current drawn depends on the load, ie the prop size and motor rpm.
Not on the ESCs or battery. Those provide the upper limit of the current you can draw safely

With a fully charged 3s lipo, a 2200kv motor will run at over 25,000 rpm on no load, ie, without prop
If you mount a 7x3.5 prop, it will shed its blades within a few seconds. (Personal experience  )
I use a 6x3 with 3s lipo on a 2200kv motor.

If you use a larger/stronger prop, it will overload/overheat the motor, ESC and battery.
My 800gm ST360 flies easily with 8x4.5 on 1050kv motors with a a 3s 2200mah lipo.

So if you answer the above 3 questions, members will be able to give you meaningful advice.
Best wishes.

Ans 1- I havent measured the weight sorry but can be around 600-800gms without the battery.
Ans 2- my battery is 3s lipo 30c/60c 3000mah
Ans 3- I bought motors from amazon- 2200kv 22T No branding They are those copper ones.

My props are 1045
The esc I have are those red colored with just simonk 30a written on them.

@pinak28,
Measure the dia and length (excl prop shaft) of the motor.
For example, 28mm dia, 26mm length is a 2826.
Then you can look up the specification of a similar Turnigy motor to get an approximate amps/watts figure for your motor (and the recommended prop size)

Without a wattmeter to check the load, you have 2 options
1. Get 6x3 props (having a strong hub to blade connection, not the flimsy ones). See pic.
2. If you have a 2s lipo, try it, as the rpm will be less than with a 3s.

(I will be offline till 25th)

@kkiyer
I think its 2212 on the motor.
And if I get 6030 props will it solve my problem..as i found out that 1045 are good for 1200kv motor only.
and 2200kv motor requires max 6030.
So will propeller solve my problem..and is this whhy my esc stopped working.

[kiran rc]

I think you are referring to the A2212/6 motor
Here is the datasheet.

[kiran rc]

Although you can switch to smaller props, the major problem arises with efficiency of the system.

@pinak28,

1045 props, 30A ESC, 3000mah 3S.. You have everything right for a 380 to 450mm size build. A 2212 sized 920kv to 1100kv motor is the right one for this combo. I suggest you get these motors before attempting to use this system with a 2200kv motor. There is no way a 6 inch prop on 2200kv motor is going to lift a 1kg quad at <60% throttle.

[pinak28]

@kiranrc @kn8alpha
Thankyou for your replies..
I will be returning the 2200kv motors as i still have a 3 day window to return them will be buying 1000kv-1200kv motor..
And rest will be same.
I have a f450 frame and 1045 props.

  look at this motor.

[pinak28]

@ambattuhari
is this motor reliable as the price is 299??

Don't know about the website but these motors are good for a basic setup.

kn8alpha this is not the case. As you can see in the motor datasheet, it also produces the same thrust as of a A2212 1000kv motor. A2212 2200kv motors with 6" props will be able to lift a 1kg Quad in less than 50% throttle. The only thing is the higher KV motors consume more amps as compared to the lower kv ones and because of that, the battery will last shorter. You can take the example of the A2212 1000kv otors and A2212 2200kv Motors. The A2212 1000kv motors consume around 13a at max throttle with 1045 props providing around 900g of static thrust and A2212 2200kv motors consume around 26A at max throttle with 6040 props providing approx the same thrust.

@yashasr
I returned the 2200kv motors today.
And ordered 1000kv motors.
As I was suggested that the props wont solve the problem.
So I did.

@pinak28 it is always better to have a lower kv motor with a bigger prop for better efficiency. Using a 6" or 7" prog would have solved the problem but also they would have consumed almost double the power than a 1000kv motor with a 1045 propeller keeping the thrust almost same.
You had the option to return it and that was the best thing. But if you couldn't return them, the 2200kv motors would not be a waste. And also 1 more thing to note, you have to choose the motor/prop combination according to the frame like you cannot use a 1000kv motor with a 1045 propeller on a 250 or 330 frame.

@yashasr
I have a 450 frame, kk2.1 fc, 30a esc, 1045 props, orange 3000mah 30c battery,
And I ordered 1000kv motors.
I have seen 450mm quads with 1000kv motors and they fly easily.
so what should I do?

[kn8alpha]

@pinak28, no worries.. what @yashasr wanted to say is that 2200kv wouldn't have been a waste. 1000kv IS the right choice for your 450, all the best for your build and do keep us posted.

@yashasr: It's interesting that a 2200kv is producing 1kg of thrust at 50%, can you point me to this datasheet? I'm hoping we're still talking about 3s..

[Flyman]

I've ordered a turnigy tx/rx from hobbyking.com by july2017,but it's retained by custom and asking wpc license,can anybody help me about this matter.

@kn8alpha I didn't say that a 2200kv motor produces 1kg at 50% Throttle. I meant that they ( four of them as in a quadcopter) can lift a 1kg quad at 50% Throttle.

[pnkyjs]

@flyman , your query may be best explained elsewhere in this forum appropriate to the issue. You may best hope to loose the TX and get refunded by the seller, by applying for 'Return to Sender' to the Customs. No getting around this.

[pinak28]

@flyman
I can't help much about it.
as I too ordered a TX Rx but mine came directly to my home without any problem.
I think you should either got the customs office where it is detained and talk to them they might help you.
Or you should send it to the seller.Or you might just lose your money.

India direct mail shipping method is not available for flysky transmitter on banggood......how did you get via india direct shipping??

I don't know about the current situation but it was available when I ordered it.
It came without any custom charges and was delivered in 17 days.
