Default Align ESC issue

Last week I had a little crash with my 250se. The esc is mounted on the outside of the frame and that's the that it landed on when it went it (on soft sand) After the crash I notice now that the esc gets very warm well hot when the heli is plugged in. There does not seem to be an issue with flight as of yet. Any idea's ?

Well assuming it didn't get hot before the crash!

I interpret the heli being plugged in that the motor isn't running, but the servos are powered. I would look at the servos, one may be having issues.

You can unplug all seevos and then plug in one at a time seeing if the ESC (actually I think it is the BEC in the ESC) warms up a lot.

Maybe you didn't notice it's before, but my stock 15a esc will get warm (fairly warm, but not too hot) whenever the battery is plugged in, wether I'm flying it or not.

It could be something you've never really thought about before, but then again, it could actually be hotter now than before. If that's the case, the something may be awry.

the esc heat is usually from the BEC working not the esc itself. Make sure all your servos are still fine, and theres no binding or damaged servo gears.

Almost hot is where mine gets, but you should be able to touch it for more than 5 seconds.
