Hi,

Sorry as I am a newbie for this.

Please advice me on the following if there is anything wrong.

Am using a 1000mah 25C battery with the following combination

1. 25A ESC and 33 Amp Outrunner.

Will it burn the ESC ?

Thanks in advance.

Dun be sorry to be new. We were all one before. Just say you are new will do, so that people knows your bkground to best advice you.

Regarding your question, can't really answer. It depends on what prop you are running and besides, we do not have info about your motor make, check the manual, they will normally recommend a prop range, I supposed that will pull the 33 amp you quoted.

You have a battery capable of putting out 25amp continous (1000mah /1000 X 25). As far as what you have listed, if the prop you are running demands 25 amp, then you are ok. We will need more info about the brand and whatnots to advise you further.

Thanks so much for your reply.

The motor is set up for EDF. Base on the setup the maximum current will be 25A.

Chances it might over heat the ESC when the motor demand more current.
On the other hand the battery deliver about 25A.
Do I need amp meter to measure the current draw?

The 25A you mentioned is what the manufacturer stated?

Give us the full picture. Some questions first:

- What make? Brand/ model of fan, motor, esc
- How many lipos you are running

I can answer the 2nd question, you definitely need a meter if you want to use your equipment more meaningfully and for the longer run.

Sorry to keep u guessing. Here is the details.

I bought a 55mm EDF Kyoshio plane and it comes with stock inner runner and 25A ESC. I do not have the specification as the box did not state any info.
I had found out that Kyoshio plane are mostly under power, so I intend to upgrade the power system. The recommended battery is 3S 900 to 1300 mah Lipo.
I manage to get a lighter out runner for EDF 5000kV max current 33A.

After doing some research and reading on others who had tested different type of ESC. I think I had figure out myself, but still unsure if it will burn the 25A ESC.

Best bet is to get a meter to measure static am draw. I have no experience with that motor and am not sure how many s you want to run the 5000kv motor at.

So far, I know it is a outrunner 5000kv but not the brand/make. I know you are using a 1000mah batt but how many S?

I had to make a google guess and saw http://www.rc-fever.com/topband-edf-...1a-p-7212.html

SPECIFICATION
KV: 5000
Weight (g): 54g
Voltage (v): 11.1
Shaft Diameter: 3mm
Load Current (A): 33 (this means tested load data, not max amp)
Max Thrust: 560g
No-Load Current: 2.7A
No-Load RPM: 56820 Load RPM: 40000
Test Condition: 55mm Ducted Fan

So assuming you are running 3s and assuming it really draws 33a, your 25amp esc won't do the job.

yeah ... ur guess is right on the motor.

Thanks for the reply. I think I would need to get a 30A esc with max 40A.

get more, 45 amp is a better mark. Not much in weight diff.
