I have a futaba radio 2.4ghs 3PM witch to my knowledge Futaba has not came out with a telementry so I came across this and and I was wondering if anyone has used one and is it help full or just a money grabber says it can be used in the pits gives feed back to ur computer and has the temp etc. So from racers point of view is this worth its wait in gold to diagnose problems that could accure.
