SCX 20 pitch and roll

[ghunt]

My TZT3 With SCX 20 shows pitch and roll both with negative values.

I believe the pitch is bow down

Negative on the roll is that STB up or down.

Yes negative pitch is bow down and negative roll is listing to port,i.e. starboard up in your terms. If you think of it as a compass with zero at the top, as the boat lists to starboard the values would increase from zero and decrease listing to port.

Thank you

Was also looking for this. Thanks x2
How do you use the offset though? if you have a +2 deg roll at rest, would you put +2 or -2 into the roll calibration setting to compensate?

-2 should set your roll to 0 at rest.

thank you. I didn't see this at first

-2 should set your roll to 0 at rest.

No, you would set it at +2 -- the sum of the incorrect reading you want to correct and the calibration offset should be zero. So if you see -2 when level, set it at +2 and if you see +2 when level, the offset is -2.

That's the math I did. His original statement said he had a +2 at rest.
