I received a faulty lipo alarm- the button which let change the voltage for alarm dosnt work at all.

Always send me a mail i dont get any notifications from RCI.

Send it back to me i will check and let you know.

Being a Fanboy of quadkopters.com i hate to write this but i have to after this incident which happened today.

one more quadkopters simonk 30A esc smoked for no reason.this is the fourth one which smoked and killed another motor.

Incident 1:Bought this thing first somewhere around december last year and smoked just few mins after i connected it to the battery.
motor ran for just few seconds and stopped. i tried to give throttle but nothing happened but this time the motor started to give some sound and started smoking. Hobbyking donkey died a horrible death. though it was the problem with the motor and replaced it with emax 2812 and that too smoke. so narrowed down the problem to esc and ditched both motors and esc and bought some emax 2812/hobbywing skywalker esc and everything went happily.

Incident 2:the tricopter bug bit me and bought 3x bumble bee motor and 3xquadkopters simonk30A esc. i thought the first piece i bought was faulty and hoped there wont be any problem with those anymore. and those esc proved me wrong. the moment i connected the escs one smoked and burned. i immediately called satya sir and he accepted to replace it. and my tricopter build was over and everything was going fine again.

Incident 3: one fine day while i was flying my tricopter i sensed something wrong on second flight. but i choose to go with one more flight, but this time i can see clearly the motor slowing down and stopped sending the copter into a fast loop and crashed into ground from around 15feets. the speed at which it crashed was terrible and could easily kill anyone. later did i found that all arms were broke and props are into pieces. collected everything and checked them back at home and one more esc smoked and a motor too.

Incident 4: disassembled the tricopter and choose to use the motors and esc for my plane project. installed on in my pitts and tested this today with a 10"prop. everything was running fine but suddenly the motor stopped and made sound. and one more esc smoked today.

In all the above 4 incident, except the one which failed in the tricopter all the other escs smoked while i was holding them in my hands and i could certainly say they never went warm before failing/smoking. they just stopped after running fine for few seconds and smoked all of a sudden.

No chance of overpropping as i was using recommended props and the esc were well above the limit of the motor.

no short circuits between the motor wires and they were secured with heat shrink sleeves. no reverse polarity, no cooling issues, they were kept in open and not enclosed anywhere during working. be it the tricopter/flying wing/pitts python all time the esc were kept in the open and well ventilated.

the motor were running fine and there is no binding/struck issues even after they smoked. above all the way the esc failed remains same for all the escs. and they behaved same after failing except one which burned!!!

Im sure there is some sort of manufacturing defect with these escs or they might be overrated/made of some cheap components which fails eventually. i still have one more esc left which still works fine. this is not a matter of money i have lost but its about dissapoinment/frustration while something fails for no reason and stopping you from completing your project. and about the chances of accident that could happen since the ultimate use is with multicopters which flies over someone's head eventually. Hope Satya sir comes up with some solution to this.

I would still recommend this shop for other best products and the service offered by him but was totally dissapointed with one particular product the 30A escs. whats so paining about them is that they dont fail alone, instead they smoke the motors too.
Can someone please share their experience with this particular product if they have any.

Ashok.P

Ashok - I had bought 3 nos of the same (haven't used them) - good thing that you have bought this to light - I will test my ones with a spare motor and revert .

Have you tried cutting off the shrink wrap and examining the components ?

Satya - will you accept returns ?? My ones are still new in the package.

@Ashok, when did this happened? i mean we had 2 suppliers of these 30A ESC, i was having lot of issues with my first supplier (i got around 20 x 30A back) i had to change the supplier.

The new 30A that came in to stock last month i.e. April is from New Supplier and till now have sold over 50 pcs of them and haven't received any complains so far.

Yes from the previous supplier, i did received few complaints. I immediately stopped selling any 30A from that stock (still have over 15 pcs 30A lying around)

Could you please tell me when did you bought these 30A was this before April or post April?

@saikat surely i can accept return but i cannot refund the money would you be interested in buying anything else instead of those? But instead can you please test them and let me know your thought's about it? cos the ones that you have are from new supplier.

Satya - no money required , store credit is good

You sent my esc's on 19th April , would these have been from
the new stock ?

If yes then I plan on using them

Yes orders that was placed in Jan/Feb for 30A was from old stock from old supplier which was having many complaints. So we removed 30A from stock for 1 month (March) and from April we got a new supplier for 30A and the ones that you have are from New Supplier,

If you can please test and post a review it would be very help full. If they get burnt or cause any damage i would take them back with no questions asked.

@Saikat,
one esc got burned and smokes everytime i connect it to a lipo either with or without a motor.
all the other escs smokes only when connected with motor. so i choose to use them as a 2A BEC for my upcoming nitros.
i ripped open one esc and found that the current booster esc has popped open . should be some poor quality ics. but surprisingly they never get hot moments before failure. it was fine and then it stops and it smokes. all of them !!!

@Satya sir.
Thanks for accepting a replacement. those escs were bought somewhere around jan. and yes i will test these too and let you know the results but will take some time. my copter is broken into almost pieces and two motors already smoked. can take up to one month to fund new motors and frame. luckily KK board and Lipo are still fine.

PS: eyeing on the fiberglass centerboard in your store. will buy them in few weeks.

Ashok.P

Dear Ashok when you place order for the frame please do drop a mail to me i would be add the ESC in them.
