Jeez man, I will get slammed left and right for this one! I believe that you need a computer radio with PCM capability JR is my choice they have an 6 channel I think I have been using the 8103 for a few years and now have the 9303 aswell,very simple to program and use. You can buy just the radio and a lot of people take this option because they already have servos and receivers or you can buy the receiver with it. At the very least a 6 channel radio would be preferable.When you program the choke into your new radio please try and use a knob rather than a switch (personal experience) it is very easy to hit the switch by accident. Hope this helps.
