Hello, I am new to the flying field.

I have a2212/6t 2200kv BLDC motor + 30 Amps and using 9X4.7 Propeller. using this combination my ESC always burst please tell me whats wrong I am doing my 2 ESCs was burst and I don't want to burst 3 one.

Thanks in advance.

I hope you didn't join battery's Red with esc's black wire...

Or didn't leave the connectors or soldered wire open so that it can short circuit

What is the name of esc is it a yellow colour no name?

No, battery's polarity was the same and even I properly soldered the wires and wrap the tape around them.

Note : Motor always runs but at peak throttle, ESC gets very hot.

It will happen

Yellow colour

Does your motor run only at peak throttle? Did you check the tx settings??

But what plane  are you building?

No, I have already calibrated the transmitter before testing motor.

if every thing is ok meaning the connections etc.

then your motor is pulling too much amp which are beyond esc capability.

9x47 prop on 2200KV motor is wrong combination @ 3s battery.

try running motor without prop and see ... if all is ok, then use a smaller prop, usually <7 inch prop.

you can use a 40-60 Amp esc but then your motor or battery will get the hit .

Thanks, I was also thinking that was due to the propeller. I tested esc it worked smoothly without the propeller and once I attached the propeller it become way hot.

FOR A 2200 kv motor use a small prop preferably under 7 inch as pointed up above... the prop is too much for the motor to handle

Use 6x4 prop or 5x5 prop

If I replace 2200 kv with 1400 kv motor will it be ok?

Why not but now use 8x4 prop or 9x4
But before that please ensure what is type of your craft
Jet need high kV motor and 6 inch prop
Trainer need low kV and more than 7 inch prop
Before using any motor
Please follow the table given below in motors manual for prop details.

I have 3d printed yak55 https://www.thingiverse.com/thing:2863212 please tell me which propeller and motor suits this airecraft b/w a2212/6t 2200kv or/13t 1400kv + 30 amp esc + lipo 3s battery

1400kv will be suitable with 7 to inch prop with 3s battery as 20a ESC but if you have 30a you can use it. It will be much better if you use 1500 to 1800mah 3s lipo

Ok

Wow! What a choice for your first model!

Saw the site you mentioned, but could not find 3 important things:
1. Size of the model
2. Its weight
3. Whether the prototype has been flown successfully

Without this data it's not possible to select a suitable propulsion system, (motor wattage, kv, prop, Esc)
Choice of Lipo, 2s or 3s, also depends on these factors.
The capacity (mah) of the lipo depends on how much weight the model can carry.

So the suggestion that 'a 1500 or 1800 mah 3s will be much better', seems premature to me...

I presume that you are aware of the suitability (or otherwise) of a scale Spitfire (that may perhaps be quite heavy) as a first model for a newcomer to build and learn to fly on...

@tictoc21
Much better than what?

@ K K Iter sir,
I'm guessing if raj_flyer is using 2200 mah battery, then he may unable experience 3d flying on his aircraft ( as he only mention 3s lipo cell and not it's capacity), so it will much better to use 1400kv motor along with 8 inch prop having 1500 to1800 mah battery rather than 2200mah as most of beginner tend to buy 2200mah.
That's not perfect formula sir , as his choice is mid wing , so I post it according to my experience it is his choice to follow or not.
But which battery capacity will you recommend him for his 3D printed yak55sir?
And please do correct me if I'm wrong?

I am using 3s 1000mAH battery. I also do have 2s 2200mAH but it makes plane heavier.

how do you balance the CG ?

if you  are able to balance CG with 1000mah then its the best to use. keeping AUW lowest for plane.

Select a appropriate motor depending the weight of your printed plane...
