I have a Weatronics in my FLASH on 72mhz and it has been rock solid. I have one antennae using a Deans two piece base loaded whip mounted in front of the canopy and the other run back through the fuselage on the opposite side of the wiring going to the turbine. So far, with about 25 flights it has never had any loss of signal. Always uses # 1 antennae, which is the base loaded one, and no frame loss on the # 2 either!! I am sold on these receivers! They seem pricy but when you consider what is in them, 2 receivers, redundant power supply, voltage regulator, gyro and GPS! Install the same things individually and see what that total is! For me, just 2 of the Futab G3 receivers is more than the cost of the Weatronics!!
