Sidewinder ESC Q

[fastbaja5b]

Looking at the Sidewinder SCT for my SC10, my question is what are the BEC specs because for the life of me I can't find anything besides that it's 5V (Which is fine, my Savox SC1267SG Servo runs from 4.8 to 7.4V but the main thing is AMPS.

An EZ-Run ESC BEC only churns out 1.5A, resulting in glitching, things going haywire etc etc

A Hobbywing XERUN has a 2.5A BEC, and all is happy and fine. Ditto for the LRP SPX Esc with a 3A BEC

would help if I knew what the Amp rating was of the Sidewinder SCT BEC (Assuming 2s Lipo) so I can see whether or not I need to change servos or buy a BEC.
