hey i have read the entire post and its very usefull for a beginner and a very good revision of first year engineering. 

Thanks rajathv8...there is a lot more to come...just not able to find time...i think i should keep this on my priority list now.

Regards

i would like to see a write up on brushed and brushless motors and respective esc. its advantages etc. since im a beginer here even i dont have good knowledge on these topics.

How did I miss this thread? For an idiot like me, this info is like a goldmine! Thanks Ankur, thanks a ton!

Great friend..its a great effort to give a better knowlede about battery motor relation ships...but with a little doubt..is there any need to go to this extreme to geat a perfectly working model? we know there must be a burning theory behind every stuff.by understanding the OHM's law, all we know amperage in a circuit automatically increases as the voltage increases.so here we need only one thing.we need a perfectly balanced system of motor and battery, for optimum performance of the craft, by avoiding burning out the motor and battery pack..we can simply overcome this phenomena by adding a controller circuits in between battery and load. a simple circuit wired around famous IC 555, wedded with a mosfet will clear all the probs related to this matter.have a nice flying

I want to understand ESC compatibulity i.e. which ESC is suitable for a specific motor. It is said here that ESC should be rated higher Amp than motor rating  but how much higher?

I am struggling with burning of ESC's. In my belt CP Heli, its default ESC was a 25 A ESC which burnt just after its first flight. I purchased a new HK ESC with 30 A rating. I managed to took it off for second time yesterday and I found fragrance and fumes of buring ESC again.

Please advice if 25 and 30 A are so sensitive for Esky Belt CP then what should be the ideal rating for an ESC for this heli ?

How does it affect the setup if I go for a higher Amp ESC's say 40A of 70A?

Wishing you all a very happy new year and Congratulation for Anwar for hosting such a nice and helpful forum. (People ask me if I am on Facebook .......I answer them, I am on RC INDIA  ...... this is my own social network.....infact this is our own special social network ) 

There is absolutely no harm if the ESC rating is much higher than needed. The only penalty is weight and cost. The first,slight, the second, much more!

if u now have burned 2 esc i would guess something is wrong like a binding servo or similar. do u bang on the lipo and still have blades in blade holder?

hey didnt get you? please exlplain and help me as wot might be the psooible cause

it is sometimes common that people  do not take blades out of blade support for transport before they connect battery and cyclic servos are

stalling and bec in  esc is burning up

No its not the case, infact one of my friend told me that the motor installed in this helli require a better rated ESC like 40Amp or so, now upgrading to 40Amp lets see. Btw Happy New year and thanks for your kind reply. 

the post is very gud. since i m a beginner, it was very essential for me to understand all of this. i just wanna say thanks a lot to u

Ankur, can you suggest me a motor...........
My planes weighs about 1 Kg.
I want suitable motor for 6x4 prop.....

ntm prop drive 1800kv with 4S, works great with 6x4. I am using this setup on my f18 and it rocks. 1080grams of thrust.

dear all,

i have scrath built Katana 40" span with 9mm EPP foam, it wieghs 375gm with servos and push rods,
plz suggest me the power plant.
 and props

hi,

here is a good example of how to calculate power requirement of your model.

good for the electric flyers.

regds

Oh wonderful. It will definitely help in our so called "project"...

Thanks a lot.....

 

great help..

here's a video i made for begineers.Correct me if iam wrong senior guys.

hello,
Can any one please tell me what are speed controllers?and are they necessary while building a rc plane for the first time?
Thank you.

Unless your making a RC airplane that doesnt have throttle control you wont need it. But throttle is the basic control fucntion of anything RC.
ESC(electronic speed control) that is used to control brushless motors is used for airplanes. If you are going to used a brushed motor then brushed motor controllers are also available. There are two benefits to a ESC. It gives throttle control, and ones with a built in BEC or UBEC also eliminates the need of having a separate battery for your receiver. If your making a free flight powered model you wont need this. Though if your making a 2 channel RC plane or 3 Channel plane then the first channel itself should be throttle, provided by the speed controller . So my answer would be yes if you are building a 2 channel rc plane or more.

hi rachit, welcome to rc India... please before asking anymore, go through online resources and read up.. also visit the rc India gems page.... most of the questions which newbies have  already been answered.. all you gotta do is find them...
a speed controller is a very important part in hobby grade rc. it takes signals from the receiver and controls the motor speed accordingly. in some cases, it also powers the servos and other electronics on the plane, by diverting a small amount of power from the battery to these components

you will understand more about this as you delve deeper into this hobby...
 hope this helps
