I was out at the field today with my TRex-450 and everything was going fine. After a few minutes of flight, I landed the heli to make a minor gyro adjustment on the radio and I was right up in the air.
The heli was about 20 feet in altitude and I decided to go for some inverted hovering. As soon as it got inverted, the motor began to slow down and the heli was falling!
At this precise moment, I was thinking about some mechanical problem and I could't understand why my motor was failing. So the heli went all the way down.. inverted!
It all ended with a light crash, when the heli hit the wet grass blades first. It looked like some really not wanted inverted auto and the heli fell not too fast.
I went over to gather it and fortunatly it didn't hit very hard. Only the blades (which were already lightly scratched anyway) and the flybar are damaged.
This is only then that I realized what just happened. I simply forgot to flip the idle up switch so as soon as I went inverted and started to lower the throttle stick, the power to the motor simply decreased!
The good news is nothing is wrong with the electronics, it was simply a pilot error. But now I need some new blades and flybar!
