selecting ESC for a brushless motor

[bsuvansh]

i bought a brushless motor which requires 70amp ESC with a external BEC
unfortunately that 70amp ESC burnt up
now i was just trying that motor to work with my another brushless motor's ESC WHICH WAS 20amps only
when i connected all the wires and fired it up that motor starts working
i thought that that ESC wont be able to talke the load of the servos im using so i
gave it an another try with all the 4 servos connected and then also everything was working good

so i want to know
that will this coonection do any damage to my electrical system like the motor,ESC,snd the servos

If the motor requires a 70amp esc your 20amp might run it for a short while under no load conditions but the minute you load it up it will FRY!!
It may also damage your motor. Don't risk it, get the right esc.

Get an 80a esc and call it done. Putting a 20a esc on a motor that can draw over 70a is just asking for a fire! Safety first.
