I'm just looking at the 1cell stuff being a nitch market as is. Most hobby shops carry 2cell stuff. Not to say they don't have 1cell stuff but I'm sure it doesn't move as fast. And for the manufacturers if they aren't selling the volume of 1cell stuff as they do 2cell stuff the profit margins will be low. Most companies have to look at that to stay viable. Which is why you don't see every manufacturer making 2cell esc or even multiple 1cell esc.
