What is the difference between a Sidewinder SV2 and SCT versions?
 

Like the title says, what is the difference? Programming? Are they physically the same ESCs?

Have you tried looking at CC's site and comparing the two?

the sticker on the case is the only difference

I belive it even says that on castles site.

+1...sorta. I don't believe CC states anything, I emailed them with a vague reply. Basically the same ESC, different motors when you buy a "set".
The SCT is cheaper by itself, my son is running 2 of them in a 2.2 Bully MOA.

The only thing I could find was that the SCT was a combo, and you could get the SV2 by itself. I understand they are the second generation compared to the original Sidewinder, just didn't know where they differed. I kind of assumed it was just the SCT version to be with the motor so you could buy them as the set (kind of like the MMP / 2400 combo).

Per Patrick Del Castillo, the owner of CC, they are the same. He said so on the rc-monster forums.

Well there ya go! "thumbsup"
