How do you know if the motor is still ok after a crash?

Hi all

My buddy is offering me a Hacker B50 7s + 6.7:1 GB at a very good price. Say about $165. This motor have nosed in recently to medium soft ground. The fuse total and the Hacker Master FAI controller kaput as well.

He bench test the motor ok, no noise and still smooth.

I'm thinking of borrowing it for a flight before I confirm.

How else can you check?

If you have a "Whatt Meter" you can power it up to the specs and see if it matches. Any binding or such will raise the amp draw higher than the spec.
