RE: Aurora or JR 9503
The Aurora does have the telemetry. The receivers can also be powered by a separate battery (up to 35 volts) that does NOT also power the servos. The receivers are priced reasonably, too.
6 channel ~ $42, 7 channel ~ $58 and the 9 channel ~ $90. Couple that with the initial price (~$350) and it's a no brainer.
