Sidewinder SCT ESC Issue

[TexasSP]

I have seen this plenty before. Many of today's faster and stronger servo's demand too much current from BEC's. Many of us have found it good practice to use external BEC's. This is pretty much standard practice in the crawler world.

Its the stock slash servo though. I am guessing that sence this happened the BEC in the ESC is a gonner so should he send it back to Castle or just buy a BEC?
