Hello,
I am getting started with a brand new Hubsan X4 H107D and have the following problem :
When I try to liftoff, only two motors (the ones on the left side) are spinning, so the quad will flip immediately.
Here is what I have tried so far :
- I have done the calibration of the transmitter stick.
- I have checked that the props have their correct positions (clockwise, looking down on the quad, and from the front left, BABA).
- All the trims are at 50 (no correction)
- I have done the calibration of the accelerometers on a flat surface. Afterwards the led are blinking, so the calibration is done. I have also tried in various other positions that are not flat with no change.
Now if I try a liftoff, only two motors are working, the ones on the left side of the quad, so the quad will flip. They are spinning in the expected direction for each of them.
If I use the rudder stick to the left (maximum shift possible) when trying to lift off, then three motors (including the two on the left side) will spin, but the third one is weaker and the quad will flip again. If I use the rudder stick to the right, then three motors will spin (the two on the left side, plus the remaining motor). The same happens if I use trims for a maximum correction in either direction.
In all cases, I have never (or only for a very short time) 4 motors working at once, but they work separately and in the correct direction for each, and when they work I can feel the air flowing below the quad.
It looks like a problem of calibration of the accelerometers, but calibration does not help, neither does a calibration with the quad leaning on either side.
Any idea on what I can try to solve this?
Thank you.
