Hi, first post here.
I have been happily flying my phantom 1 for a bit over a year with no issues. Current firmware, consistent calibrations.
Had a decent crash (my fault) clipped the top of a really tall tree, broke a prop and fell from the sky, and since can't calibrate the compass. I can enter calibration mode (light turns solid yellow), I do the horizontal spin (light turns solid green), I turn it nose down and do the vertical calibration... but the light just stays solid green. No mater how many times I spin, or the angle I tilt, or how fast I spin, just stays solid green until I flick the gps/atti switch to leave calibration mode. Everything else seems to function (getting full satellite reception, not getting compass errors).
What I have done/tried"
- basic and advance IMU calibration about a hundred times.
- Compass dance so many times in multiple locations (inside to the middle of nowhere).
- inspected the gps puck for cracks, all good.
- inspected all connections inside, checked for damage.
- reinstalled firmware.
- removed and smacked the naza m sensor on all sides.
- degaussed the compass and re-calibrated (numbers are good).
- tried a new compass... same thing stuck on vertical green solid light.
- feeling fed up, I took apart the case of the sensor to look for physical damage or stuck sensors, couldn't see anything wrong.
In the tools / IMU calibration, all the values seem fine EXCEPT acceleration(g). After advanced callibration, the X and Y values go to zero and don't really move. They just fluctuate between 0.00 and -0.00. If I move, shake or tilt the Phantom I can sometimes get the values to move a little, but only maybe to 0.02 at the most. Watching videos on the web, I see people handling their phantoms gently and the numbers are bumping up and down to excess of 0.10.
Thoughts or insight?
Does that mean the accelerometer sensor is broken? sound like an issue inside the Naza box? or somewhere else? Where is the acceleration sensor and how does it create the values?
If I cant get the compass to calibrate, is it still safe to fly in atti mode? never tried manual mode... is that safe? I did a test flight, felt unstable and fishbowly with gps and atti, but it was also really windy.
There is a local place (outside of vancouver) that charges $70 for a diagnosis, but after buying the new compass and props, don't want to spend more if i'm just going to find out it will be hundreds for new parts...
If I could just pinpoint the issue.
Any help would be appreciated!
