thanks Ashish.
Tools that I used were a simple cutter, cellotape, hot glue gun. & yes pencil scale etc.
Nothing special or expensive.

Sharing my video on pre-flight test setup.

vikalp11

Hey people,
I did a bench test today.
Here's the video:
Part 1:

Part 2:

vikalp11

Notice a beep at the end. Didn't understand what was that for? & the ESC had also become quite hot. Had tested for just 2 minutes. Why did it become hot so quickly? The motor & battery were cool though.

coolpratheesh

Vikalp I think your ESC is of less AMPs than the motor. Thats why the ESC is heating up. Thats just my opinion. What do the experts have to say on this?

vikalp11

its 30A & motor requires 18A(normal) & 25A(burst).
other reason could be bad connection due to bad soldering?

coolpratheesh

I dont think soldering would be that big a problem ;)

vikalp11

Hmmm....
My soldering was good & strong. Is the motor+prop combination conduming more amps?? Motor requirws 8x4 but i used 8x5 prop. Could it be 'coz of increased prop pitch that it is pulling more power?? I have a 6x4 prop too. Will test with it tomorrow.

coolpratheesh

but you are saying that the motor is not at all hot, if that was the case then the motor also would have been hot.

vikalp11


sunk?

HI mate.
you are running 11v ?
is the bec a switching beck or not? the bec on 11v may be getting hot just by reducing currant for rx,servos etc.
on 11v I always put a separate bec in as it save the esc getting hot.

vikalp11

Yes it is 11v battery. The esc has buitin bec of 5v for tx & servos.
Will study more over it & speak to the dealer too.
Thx for the input.
