If it is just 2 ESCs in one box, they are right. These days, mixing is often available in the transmitter. In the advertising, I see no mention of built in mixing. , look at the price of the Action p95 (but bear in mind that the Action one quotes real, rather than imaginary, amps). As an alternative, a hardware mixer can be fitted in the boat. At the price, still a bargain for 2 ESCs, hoping for a free mixer is just being a bit hopeful. Next year, who knows?
