Everyone will have a different answer for you. I like Futuba systems. They are reliable and cost effective. Get a 2.4Ghz system and determine how many channels you anticpate you will need now and into the future. The 2.4 Ghz technology is here and can only get better in terms of what the radio manufacturers bring out in total systems. The existing FM and PCM systems are good but 2.4 Ghz is where to go now.
