So here is a 12 A esc by rcb
And here is the 6a esc.. http://rcbazaar.com/product.aspx?productid=2307
Please don't buy the 6a esc..
I bought it thinking it would be really light weight ..I mean at least 30% less weight...but it wasn't...each is good but makes no sense buying it..coz you might just get a better blheli one...and they both weight almost the same...
Of course there are other outlets....with better options maybe...
Just wanted to share my little experience..
