This is probably common knowledge within the pattern community, but I'm new.

So I'm reading-up on the rules from the AMA's Comp. Regs. (2013-2014), and it states in Para. 4.4, "Electronic or other signal feedback from the model of any kind.", is not permited. This statement is under the title of "control functions" not permited.

So the question is: Some radio systems these days offer as routine, "telemetry" that at a minimum allows the pilot to read RX voltage from the transmitter. This transmitted data from the aircraft to the transmitter has nothing to do with any of the model's "control functions" per se (the pilot can't use the data to effect how the aircraft flies), and it's a nice safety feature, but...it is "...signal feedback from the model..."

So what's the "ruling" on this issue. Again, I'm new, and it's probably an old question. But it's new to me (-:
