one of my favorite things to do if i'm wondering about an esc, (after i resolder the bullet connectors and battery connector, check it with a programming card if available and inspect it visually) is to put it on a large foamie and fly a bunch of packs with it . if it passes that test then i'm willing to put it into the balsa plane/more expensive airframe. i do this with crashed suspect speed controllers on my multirotors before putting them back on a quadcopter because we all know what happens if a speed controller goes bad on a quad.........when you do foamie flights make sure to do some choppy throttle motions to see if the esc is resetting or slow to give throttle back.
