I am playing around with a Turngy/FRsky IA4 stick radio on on my endurance boat. It has better range than my GT3-C but in testing for signal fail (turning off the transmitter) the esc, SK 130 HV, does not cut off but just keeps going. It cuts off with the GT3-C though. I know it is an aircraft tx but the esc should still cut with a loss of signal.
Any ideas?
