burnt esc

[Shayne]

Hey guys, i was wondering that if your esc is very hot that caused some wires to melt and you batt to bloat like crap, what could have caused it??

look like your prop size n your current motor is not at the right setting

okok, ic, but the motor i am using is stock motor, i am flying a C 160, then i bought a 30A ESC

Excessive current draw can be dynamic condition, not just simply based on your setup. Sometimes, a banged up motor, which becomes stiff, will caused the current draw to rise rapidly, not to mention if you have a multi engined aircraft.

The best diagnosis is the measure the total current draw, followed by individual motor current draw, using a digital inductance type ammeter, like the Kew mate 2000 multimeter.

Without any measurement, everything will be just based on wild guess.

Mind to share the following?

What's the model # of the motor?
What's the prop. used; i.e. 9x6, 10x8 etc.?
What's the batt. used (3S, 4S...)? and what the C rating (20C, 30C)?
Are u running the shared batt. or individual supply?
Sharing : 1 batt, 2 ESC, 2 Motors
Individual : 2 batt., 2 ESC, 2 motors.

Which part of the wire melted?

From your above statement, I assume u are using 30A ESC at that point of time.

the motor, prop:127x76(mm). batt is 3s, 20C. then i am using 1batt, 1esc, 2 motors, mine brushed.

Battery 3S!!!!!!???????? These motors won't stand a chance on 11.1V norminal, not to mention 12.6V full charge! These poor motors will at the most take 2S as they were orginally designed to run on 7 cell Nimh or nicd (8.4V).


ITEM : GW/EDP-300HC


MOTOR : EM300H


WEIGHT : 49g (1.73 oz)

W/EM300H MOTOR , EP5030 PROPELLER *1, 4", 5" RUBBER ADAPTER *1

Factory standard product : GW/EDP300H(EP5030) Spec of other propellers are reference for optional purchase.

RED = High voltage ( 8.4v and above ) boosts power , but fatally damages the motor

AT 12.6V, the motors can't even survive even without a load. With these props, the current draw will shoot up exponentially! No wonder you see smoke. Your equipment is bound to doom!

Transall C-160 using brushed motors and large blades.. i am concerned indeed.

My heart would be wounded if the plane were to go down in flames

Joe has given the right assessment to your incident, in brief, u made a wrong power set up and load (prop. used) selection.

Thanks guys for the advice, no wonder it burnt the freaking wire. Thanks bros
