Hi Chris,
If you are wanting to upgrade to 2.4gHz operation make sure that you upgrade to a proper Hobby Grade 2.4 gHz system. Do not be fooled by the offerings by Taigen or Heng Long. They may operate on 2.4 gHz but the Taigen system at least does NOT conform to the usual standards. This means that you will not be able to take advantage of the squillions of products out there designed for the R/C hobby.
The first place to start is with a good radio and in my opinion there is nothing better for tanks than a Turnigy 9X running custom firmware. I am certainly biased here but there is nothing better for the money than a 9X or 9XR running tankER9X.
What is so good about tankER9X:
-Allows you to assign the wide variety of switches, pots, & sticks to anything you desire allowing for great control options for your tank
-Has a number of templates to allow for easy setup of tank control boards
- the latest release of tankER9X replaces all the confusing plane terms with tanks ones for ease of use
RUD (Rudder) is STR (Steering) in tankER9X
THR (Throttle) is MTR (Motors) in tankER9X (some versions may have this as ACC for acceleration)
ELE (Elevator) is GUN (Gun control) in tankER9X
AIL (Aileron) is TUR (Turret control) in tankER9X
- adding to all of this you get PC connectivity via a separate USB programmer.
Here is a little video showing how quick and easy the conversion can be using the 9X and our RC5HL control board
Tank ready 9X or 9XR radios can be bought from the RCTA webshop

Our RC5HL is probably the cheapest option as it makes use of your existing RX18. However there are a wide variety of options out there depending on the depth of your wallet and skills as a modeller.
