I have had many sonar probs over the various releases and now I have gotten it working beautifully. I have the MB1200 (XL-EZ0) sensor, currently on 2.0.37 on stock AC frame. Initially I had the sonar hung with spacers 2" under the main body under one ESC. I just used 3 unshielded hookup wires. The results were not pretty- (red=sonar green=throttle)
Then I put the plastic ring from the sonar mount kit on .5” spacers so it was even with the sensor face. Data got a lot better-
Then I installed shielded wire (shield + 2 wire) and mounted it out like this- (Great use for old leg!)
And the data became –
This flew perfectly – easy to see as it crossed from cement to lawn and to curved cement without missing a beat. Height tracked the ground and the motors stayed very smooth.
We are getting closer everyday. I still wonder – is it possible to hack the software to enable alt hold while in simple mode or are those very separate functions that can’t run simultaneously?
