I have a M11 with the standard Spektrum with the standard spektrum recievers, i have seen this new (er) spektrum high response module and recievers.. they are kind of a see through gray. what is the difference between the standard and the high response?

Transit time. You would need pro receivers though.

when you say transit time.. hmm? I have noticed that if my car is more than 100 ft away- from the time i give it thottle or steering it seems like it takes a moment for it to respond.. thats why im askin but as long as im within 75ft or so it is instant. thanks.
