With the matchbox though you don't have to set the endpoints which is nasty with the hitec programmer and what i like best about the matchbox is that you can plug a battery into it and that powers the servos the matchbox is using. That way each servo is still getting 6 volts instead of having 6-8 servos all coming out of a reciever. You don't have as much drain on your reciever battery that wat too. Or if you use a Lith Ion battery and have a 6 v regulator with multiple outputs you can have a more redundant system (each battery goes to both recievers and a matchbox).
