I am looking for a new tx/rx for my e-maxx with dual servos, but the reciever only has one ch1 plug. Can I just use a splitter so I can plug in both servos? Will they both get the voltage they need?

Are you saying the E-maxx has dual steering servos? If so then a splitter will work. I use a slitter on planes all the time to run two servos on the same channel.

If you get a 3 channel TX/RX you can set it up to control both servos by slaving ch. to to ch.1 without using a splitter.

The new Traxxas Link rcvr has dual plugins in each channel so a splitter is not needed.

I was looking at this system http://www.hobbypartz.com/fs-gt2-24ghz-radio-black.html because it is a simple 2.4ghz system for $20. The traxxas system is $50 and I just bash so I don't need all the other features that it offers. How do you slave ch3 to ch1 like steve said?
