Crashed and compleatly smashed my Cermark 27% Edge 540 due to failed Sensor Switch, so much for failing safe.
One of the 3 joints that hold the boards together came apart, due to vibration, this caused the voltage to drop to 3v intermittantly.
The day before was flying ok then without warning it's broken.
The Spektrum RX shut down and restarted a couple of times before it hit the ground. bummer
need a new plane now, looking at the Extreme Flight Yak 54- 74"
