Jay, should I use a voltage regulator between, the ESC and the servo(s) if I am using more then then 6v to the receiver?I'd like to get more "v's" to the receiver so I can avoid the glitches,
Not sure where you got the idea that higher voltage to the receiver prevents glitches, it has nothing to do with the quality of the RF link or how well the RX deals with interference or internally generated noise. Increasing the voltage to the receiver does basically two things, it increases the servo torque and increase servo speed.
Most of the 2.4 systems are designed to run at 6 volts, but running them at say 8 volts is not going to give you a better link. Spektrum has proven to be a bit more voltage sensitive and has a longer reboot time after a brown out, and the solution was found to be running at least 6 volts. Futaba recommends 6 volts right off.
But again, this is simply due to the design of the electronics, they just take a slightly higher voltage to work. It is not to prevent a poor RF link.
I know it seems like the same thing, but it is not. Once over the threshold it does not matter how much power you send to the RX. Its internal regulator will just burn off the excess as heat.
The same goes for transmitters. All modern transmitters have essentially the same power output from fresh off the charge to shutdown.
I just want to add, despite knowing this may not sound great coming from a Futaba guy, but Horizon specifically tells people NOT to use the JR/Spektrum 2.4 systems in boats. Some have had success, many have not and Horizon feels that the challenges of running in a boat are not the strength of their system. Adding more voltage will not overcome this issue. Like I said, this is what Horizon has told several people in just the past few weeks, this is not my opinion.
