Hello
I am new to this hobby.....
I don't understand how to chose the components like ESC, motor, battery ,prop.etc
Like how many 'A' ESC to use for a 2300 kv motor with maximum current rating 27A .And the c rating of a battery.....
I have browsed many sites but in vain.....

Can anyone make me understand those things in a simple  language??

For a 27A max. current rating you'd need at least a 30A ESC. But, it would be safer (and highly recommended) to use a 35A ESC.

The 'C' rating multiplied by the capacity 'mAH' gives the maximum current you can safely draw from the battery.

So, for an airplane with a motor that draws 27A max, the minimum safe 'C' and 'mAH' ratings would be something like 1500mAH and 20C (ie max. 30A).

Suitable props are generally listed in the motor's description. Get one that provides required thrust without making the motor draw more than its max. rated current.

Thanks for your help swapnil
If I am using a 2300 kv motor , then what are the suitable ESC and battery...

The Kv of the motor doesn't determine the selection of the ESC and LiPo. You need to consider the maximum current draw of the motor.

Most probably, you'll need a 30A ESC and a 1500-2200 mAH (20-30C) LiPo.

Hi,
What actually are you trying to make?Specifying a model would make it easier for others to understand.
Please post a brief of your idea,and list the parts if you have already selected any(other than the motors).

Best Regards,

 :headscratch:Hello I am trying to make a racer-cum-trainer plane
Most probably a ft racer.......

Hi.

Selection of components starts with what type of plane you want to build. Since you have already clarified that you want to build a trainer plane you need to take its estimated weight into account.
e.g. estimated weight is 800 grams. Then you need at least 500-600 grams (pull) motor. (1:1 ratio (or more) is better so that your plane is not underpowered)

Motor- Consider that we are using a 1000kv motor in our plane. (Lower Kv motors are better) All motors come with recommended propeller configuration, in our case suggested prop is 1045. Also manufacturers on their website give you data about current and pull (in gram) produced by the motor. (Another factor to consider is price and availability of the motor)

This motor's rated current is 12A and pull is about 900grams. So it will be good configuration for our plane considering estimated weight.

ESC- Now each and every machine has a little bit of error in it. Manufactures say that, its a 12A motor but it may actually be 13A or 14A so to be on safer side add 5A to the manufacturers given data. i.e. 12A+5A = 17A. So we need at least 17A ESC. If you look at the online stores 20A ESC's are radially available. So we chose a 20A ESC.

Battery- It is the most heavy part of your plane, battery also determines your flight time and charging duration. Since we are drawing at least 17A current we need a battery that can discharge that much. Max current discharged can be calculated as= capacity X C rating, lets say we are using a 2200mAh 20C battery. Means battery can discharge upto 2.2A (or 2200 mAh) X 20 = 44A. We can safely draw 44A from the battery. Since we will draw max 17A, we have a perfect battery in our hands.

I hope this helps.

Thank you all the SWAPNILs....😍😘
I want a little bit fast plane....
Should I use a 1000kv motor??

Yes you can. By the way is it your first plane ? that you will be flying?

Yes it is.....
I understood.
Thank you

I am planning to make it next summers
When I would have a 3 months vacation

I urge you to be familiar with wing loading. Less the wing loading, easy to fly it is. Start designing, when finalized, start collecting necessary components. You still have plenty of time.

Thanks
I would be studying more and more about aerodynamics and rc electronics in the coming days......

Dont go deep into the Aerodynamics. At this scale it is not necessary, still if you are interested you may go ahead.

As far as RC planes are concerned you just need to look for the electronics how to set it up, how to reduce the weight of plane, building techniques, from where to source the materials, reputed brands, materials used in building etc.
Basically go through this forum as much as possible and other.

Believe me you need to understand little bit of maths thats it. You can easily build your plane.

For my first plane should I use depron or coroplast??

I used coroplast for my first plane. It is much easier to work with and much more durable than depron. Also, it's more readily available. Only down-side is that it's heavier than depron.

My first plane was similar to the one shown in the image below.

I have used thermocol for my first plane. It also came out good. Have not tried Coro yet. But as suggested by Swapnil you may use it for your first plane.  Waisebhi baarish aa rahi hai plane thikse nahi uda to coroplast sheet bike mein laga dega aage (beechmein hole karna mah bhulna)

Yesssss.....

I know this is not the place but still can anyone tell me what is the transmitter and receiver recommended for a beginer(6ch is more than enough) around 4000. What about rcb6i? Any other sugestions?

I think it's the most recommended transmitter...



It's under ₹3500 from banggod or aliexpress

But importing radio equipments to india needs some licesnse and type approval from wpc

No it's not that much complicated.....
My friend bought it from aliexpress without any problem..
It was delivered within 25 days....
This is as much as amazon also takes to deliver because amazon also imports it from China....

So i can import it from bangood and get it without any worries? No custom hassles?

No problem
If the package is small It wouldn't bother, but if you're calling for a big package it will have higher chances of being checked at customs.

If something goes wrong......
Then the seller will refund you
