Not a lot of them come with an included receiver(or if it is the case, check that the receiver isn't ****). And you'd need a 3 channel TX and RX so you can hook up the kill switch. If you are getting a 2 channel, buy a "Y" 2ch splitter cable on killer rc so the kill switch can be powered by the electricity going to the servos.
And what has been your experience with the Blackout so far?
