I don't think the purpose of the rule is to ban real-time transmission to the pits (or even your transmitter). I remember the rule stating that your reciever can't send info to the transmitter, but in recent review of the rules, it looks like they may have removed it.
The purpose of the rule is to prevent using your telemetry to adjust fuel mixture (or suspension settings, etc.) while the car is in motion. However, it wouldn't prohibit your pit person from changing the needle mixture while the car is in the pits for fuel.
Oh, and Asurada Sugo, I did post the exact wording to the rule.
The way the rule is worded, it still wouldn't prohibit the Spektrum or Nomadio telemetry systems, because they aren't used to actively adjust your car while it is in motion. And even though the information is presented in real time, it is only used for passive data recording, albeit manually (instead of within a self contained recording device). This rule has no bearing on adjusting your transmitter settings while the car is in motion.
