Which esc you have?Was it too ho to touch? Slightly warm is okay if your esc have linear bec as they produce lots of heat!

I have a 10amp esc ordered from quadkopters ... I was able to touch it but I unplugged the programmer and the battery soon after I touched it so as to prevent it from damaging

As you say you were able to touch it i think it is the heat from the linear becs inside the esc.....for further assistance contact Satya Sir(a very approachable person) about the issue and what kind of bec is present in the esc :hatsoff:

Title: Re: Esc heating up !!

Title: Re: Esc heating up !!
Post by: kiran rc on April 06, 2015, 04:22:10 PM
Only one esc or all 3?
Title: Re: Esc heating up !!
Post by: Himadri Roy on April 06, 2015, 04:28:00 PM
is your servo connected to the bec supply? If yes then the binding of the servo is causing the internal bec to slightly heat up but no worries as this is normal  :hatsoff:
Title: Re: Esc heating up !!
Post by: Darshan for multirotors on April 06, 2015, 06:24:12 PM
All the escs are getting heated up.... and the servo is directly plugged to the fc
Title: Re: Esc heating up !!
Post by: Darshan for multirotors on April 06, 2015, 07:05:59 PM
Just now.. When I connected the battery to the fc .. The red lights began to blink where as the blue one went off. The receiver too failed to connect as the red light on the receiver(r6b) went off. Has this happened with any of you.. PLEASE HELP ME

Hello darshan is the red wire from the remaining three escs cut? only one esc has to power the fc

Title: Re: Esc heating up !!
Post by: Darshan for multirotors on April 06, 2015, 09:11:48 PM
i have seen many tricopter build videos but none of them said that we had to cut the red wires ?? please explain... its my first multirotor and i want it to be perfect
Title: Re: Esc heating up !!
Post by: Himadri Roy on April 06, 2015, 09:20:48 PM
It is a common practice by people to disconnect the red wire of the other 3 esc. Only one of the bec supplies power to FC and receiver.

Post by: Darshan for multirotors on April 06, 2015, 09:39:14 PM
So my setup is wrong is it??
Title: Re: Esc heating up !!
Post by: gunnu on April 06, 2015, 11:38:09 PM
your setup seems fine. just remove red wire from your any two esc ( let only one esc to power your fc.)
and also which props you are using?? 10A ESC is OK if you use a 5030 it drew 9.3A with 105W at 11.4V However, if you use 5045, 6020, 6030 etc larger props you might need a 12A - 15A ESC (15A is more safe) to avoid over-driving the ESC (will result burn of ESC if it is over-current).

Can you show me what you have done ..because I can't understand it
Title: Re: Esc heating up !!
Post by: kiran rc on April 07, 2015, 03:39:05 PM
At the end of Esc wire, there is a plug/connector which which consists of 3 wires.Usually yellow, red and black/brown.Just cut or disable the red wire from two of the esc's.

Post by: Darshan for multirotors on April 07, 2015, 04:00:17 PM
is it necessary???
Title: Re: Esc heating up !!
Post by: sooraj.palakkad on April 07, 2015, 04:16:43 PM
it is not always necessary. The BECs should not be connected parallel only if they are switching BECs . connecting linear becs in parallel or in serial will not harm the bec or the load in anyway.
I haven't seen or used any ESC with Switched BEC as of now, all the ESC I have seen on sale across various Domestic and International hobby stores, all come with linear becs
There is no any need to cut of the red wire from bec output of Linear ESCs, as they won't cause an interference to each other when connected in parallel or series .
But ESCs with switched BEC or any other Switched mode DC power supplys should not be used in parallel or serial combinations, as it will interfere with each other and may cause damage.

Title: Re: Esc heating up !!
Post by: gunnu on April 07, 2015, 04:35:01 PM
suggest you to use ESC >10Amps..

regards
Title: Re: Esc heating up !!
Post by: Darshan for multirotors on April 07, 2015, 04:45:21 PM
dude this is my first build.. and my parents will kill me if i tell them that you are saying this.. so 10 amp is fine.. most of the people use 10 amp with 2400kv motors.. so lets experiment once
Title: Re: Esc heating up !!
Post by: gunnu on April 07, 2015, 04:48:53 PM
so use 5030 two blade prop with 10Amps ESC. coz it draw 9A current with this props.. so don't worry it will heat..

regards

Post by: Himadri Roy on April 07, 2015, 04:53:58 PM
Darshan try putting the esc nearer to the motor(under the blade) might ward off some heat(it does! :)) and escs will be cool
Title: Re: Esc heating up !!
Post by: Darshan for multirotors on April 07, 2015, 04:57:30 PM

now it is becoming too hot to touch and there is some smell of electricity( short circuit).. I think there is some problem.. the control board problem has occured again.. the red lights are blinking and then going off and same for the blue although it is shorter than the blue one .. then the board would kind of lose power and completely blank.... PLZ HELP

Isn't it you who earlier stated that your LiPo became damaged when just connected to ESC ?
Let me ask you one thing, Have you found out exactly what happened that time ? Are you using the same setup you used that time ?
On going through your profile, I came to see you have made too many threads  on the same or related topic. As you are new here I don't blame you. But I would suggest you create one thread, that deals only with this Tricopter build of yours. (I assume this is your first build) . You should consider the following while creating that thread ,
1) Give a Detailed List of your setup (parts used)
2) explain the problems you have faced .
3) give all the details of this build till now.

I can assure, you will get far better help in troubleshooting all this problems, if you make such a thread. this is because people can get a clear view of what you are trying to do, and what exactly happened.

Making such a thread that deals with only the build of this tricopter will make your readers understand what went wrong and where.

first try to put esc servo wire to channel 3 of your receiver , connect motor and run.. and check weather it heats up again or not.. check all the esc in same way..
