SPEKTRUM
 

Do you need to use matching servos for the 2.4ghz system, or can you use standard ones ? Am I right in also saying that you need the Spektrum receiver to run the Spektrum transmitter ? Therefore, to run 2 cars, you need 2 receivers, right ?

i believe you do need the same recievers.
servo think you can use any.

Since this is a spectrum forum. Can you mix and match, spectrum, spectrum pro and spectrum pro HRS RXs and TXs .

Yes you can mix a Spektrum pro and regular Spektrum reciever. I have a Pro transmitter and a M11. It controls all my regular Spektrum recievers, but there is a big difference when it comes to the Pro. The Pro is faster.
Mixing servos, the Spektrum works fine. I think that most DSM radios will not have a problem with mixed servos. I have both the Spektrum and Nomadio and they drive mixed servos with ease.

Does the hRS really make a difference?

What is better spectrum pro HRS fro futaba or futaba's new 2.4 FAST HRS systems? ANyone any experience?
