HYDRO PLANER.....



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  Head Scratching 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 Bang Head 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?

Clap 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  Smiley...... this is my own social network.....infact this is our own special social network ClapBow

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?

Patient Zero



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 Smiley. 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
