Mini ESC vs Regular ESC

[dmhjuntak]

I'm doing a project with these parts:

• Lumenier 900 kV Motors : http://www.getfpv.com/fx2216-11-900kv-v2.html
• Lumenier BLHeli Mini 30A ESC : http://www.getfpv.com/lumenier-30a-blheli-esc-2-4s.html
• 11" Propellers
• 4000 mAh Battery 11.1V : https://hobbyking.com/en_us/turnigy-nano-tech-4000mah-3s-35-70c-lipo-pack.html?___from_store=en_us

I tried to test out my motors by connecting: motor > ESC > Receiver -- Transmitter
The ESC instantly got fried as soon as I gave it some throttle.

Then I tested the same circuit but using a different ESC:
3DR 20A ESC: https://3dr.com/support/articles/207358766/esc_20_amp_with_simonk/
and the motor works just fine.

What's the difference between the regular and mini ESC's? The first thought that came to my mind is that if the current rating is within what the motor will take, then the motor will work fine. But it wasn't in this case.

Hmm... That sounds like it was simply a bad ESCs. There should be little difference between the two, save the slightly higher current rating of the 30A. Have you tried a different mini ESC?
