I can safely say that since installing spektrum tx/rx in all my models I haven't had any failsafe issues, mind you I hadn't had any previous issues either - mainly wanted to get one and add telemetry and couldn't afford a nomadio. The telemetry still hasn't been added but I'm more than happy with the spektrum and its in built failsafe, running 4 rx's and the one tx and all is good so far
