2.4 ghz Transmitter

[IDontKnow]

I have found most 2.4 radios work well, even the cheapie 38.00 one bought off ebay!
My personal preference is the Airtronics RDS8000, all functions work perfectly.
Have 2 myself, my brother runs 2 and other club members run them also based on my recomendations. Have also found the Spektrum DX5 and 6's to be an acceptable alternative but the engine shutdown sequence is very hit and miss?
One of the best options is to make sure you buy a system that will suit any expansion of your truck systems in the near future, four channels does not seem to cut it nowadays.
My King has the RDS8000 which is 8 channel and they are ALL in use.
