hello,
plz let me know , is this imp that all the ESC of multirotor should be of same brand.
i have 4 ESC SimonK 30A and 2 Hobbywing 30A can i use this on my hexacopter. or i hav to buy all the ESC of same brand.
thanx
It is better use same make ESCs in a multirotor.
are all the 30A Simonk ESC are same (weather they are bought Different online site.) two from india and rest of from Banggood
which ESC suits best to 900 to 1000Kv motors
You need all exactly same escs
And with simonk firmware for a perfect setup
well, here I think, we are following a myth- why??, I can explain-
When we say we have to use all the ESC to be exactly same, How can that be possible ?
Even the same model, of ESCs produced in a batch from a brand - will definitely have slight varieties in their electrical characteristics - so we cannot assure any power system we use is exactly identical to the others - even if the motor, ESC and even the connecting wires all are same.
But the point in making sure all the ESC are alike - is not brand or anything We have to make sure the way all of the ESCs work is alike - for example different f/w and h/w will have different characteristics like i/p PWM frequency , motor controlling etc.....
If you mix match ESCs, make sure all the h/w and f/w are same or atleast alike - well the easiest way we can find for this is USING THE SAME MODEL ESCs !!!!
But for simonK ESCs, we know what the firmware is, and the h/w will be definitely alike - so you can with out hesitation mix and match simonK ESCs - but ensure,the ESC can provide enough current to drive the motor
There will be lots of power difference using different esc's.Its better to use the same type of esc.
I personally use 3 DYS 30A (SimonK) & 1 Hobbyking 30A Blue series (flashed with SimonK later) on my quad. I think there won't be any problem as long as refresh rate is same for all esc.
Earlier I used non SimonK (Turnigy Plush) instead of Hobbyking & found some throttle fluctuations. Pls refer the attachments.
power difference in ESC- well even if we use same batch of same model ESCs from a brand - there will be variations in electrical characteristics.
even the power consumed by each motor is entirely different.
all we have to check is all ESCs are rated to same i/p frequency and refresh rate - which will be ensured if we use same firmware ESC with a same h/w - that will be ensured for simonK ESC s, as for other ESCs, we don't know which f/w and h/w is used. - well we have to check only whether the ESC can deliver enough power to motor, and all the ESCs f/w and h/w are same.
means i hav to buy all new ESC of same brand and from same site.
can u plz check these sites and tell me to which should i prefer.
thanx

I don't think you have to buy 6 new ESC, either buy 2 SimonK 30A . or flash hobbywing 30A to simonK . :thumbsup:
sir i dont know how to flash esc to new firmware.
well, there is lot of good tutorials around the net,
it's easy - you need a USBASP tool
ok sir ill try

well you also need some basic knowledge in microcontrollers, and soldering- but, it all can be learned.
But if in doubt, better get someone to help.
ok sir
So you have some vogue idea abt micro controllers, and electronics, right ?
no sir. i hav done engineering in electrical. i dont hav any idea about micro controllers..
well, you don't have to know everything, just identifying pin number and some soldering will do.
And no need of calling me "sir" :)
ok
off topic question but you purchase from banggood ? How do you pay ?
by entropay sir or by credit card..
https://www.entropay.com/ (https://www.entropay.com/)
ok, any similar sites you know of which allow debit cards ?
no sir u cant make payment to international site by indian debit card. they only accept credit card ( HDFC , ICICI , Standard charted , Axis )
or u can pay by creating virtual card on entropay this card i prefer the most
ok. thanks for the info.
welcome. if u want to make payment to international sites. contact me ill help u to create virtual card on entropay.
thanx
yea sure, I was actually having issues with creating password on entropay.
give your mail on PM btw.
