Question
Best Way to test a ESC

I had a plane come apart in midair(long story) and of resulted in a hard crash. I knew the motor was shot but the ESC looked just fine. When I hooked it up to another motor the motor would barely spin. So, what is the best way to tell if an ESC is good or bad?? Do I need a watt meter?

what brand of esc mate and if so might need to be re programed with a program card as motor timing mode may be wrong for motor you are trying to run

. . . Do I need a watt meter?
Yes, a watt meter is indispensable when you are making adjustments to the power system. It will tell you when current levels are too high and potentially damaging. It is also important to have the published specifications of the components you're working on. If not provided by the manufacturer, they can often be located online.

I can see the point of the Wattmeter when the ESC / motor is working combo - but here the guy has a non-working combo and a Wattmeter is no use whatsoever to him to get it working.

What he may need to do is to connect a meter to see if anything is coming out of ESC !

Personally with the price of ESC's now - is it worth trusting an ESC that you are unsure of ? My favourite 50mm EDF is in sorry state for this reason.

I agree that is why it is going in the trash, recycle whatever. I was just curious if there was an easy way to test it.

By the way the ESC is a EZ Flite 50amp ESC w/3A BEC sold by HeadsUp RC and the motor I was using ia an eflite power 10.
