Canīt say if the Cirtix works with 1S and the booster but at least works for a lot of guys here using 2S and different motors. I donīt think the ESC could burn up if the sensor wires fail, actually the Cirtix should switch to sensorless mode in this case.
One thing I noticed when running Corally or Graupner (outlaw) type motors, when running on low throttle there is a very strange noise coming from the motor. Sounds like a broken drivetrain.
