I've been looking at getting a new radio. Currently running a dx4c. 6040 or 7955 servos in all my cars. I don't really need all the features. I really just looking for low latency. I really want to have that locked in feeling while driving. I see most the airtronics stuff is claimed to be the fastest. My understanding is that with the m12s it is actually faster than what my servos will allow. Im looking for advice on which radio to buy to maximize the speed/latency with the servos I have.
