75 amp Align ESC failed or not?
Does anyone know how to test Align Speed controllers? A have had a 75 amp esc in a scale bell222 body with Trex600 mechanics, for about 3 years. Always ran faultless. Until recently, it started to get minor power surges, and then they would dissapear. On the last flt, the surges dissapeared, but it lost all power gradually. Managed to auto onto the deck, but one l/g leg collapsed, and the tail rotor struck the dirt, stripping the drive gears. Such a ***** working on scale helis!
Any ideas for testing the esc?

It is in a 450 Pro TT clone that has been flawless for around 200 flights..
In the past few weeks it had a couple of minor surges, more like glitches, and today, it just seems to be losing power.. the heli was previously "unboggable" (if that makes sense.. ) now it bogs quite badly with maximum pitch...
I also noticed both the motor and the ESC are extremely hot where they previously ran very cool..
I guess it just happens sometimes.. Like anything mechanical or electrical.. they just wear out..

I had the same issue with mine in a 450 sized MD500E. It ended up being too much heat in the fuselage that killed it. I went from a 25 to a 35 amo esc and put some more cooling holes in the fuselage, and the problem went away. Got enough cooling on your triple 2?
