RC Logger 1 I have one of the older RC Loggers. I always thought this was spot on, but last night I was checking blade pitch, and noticed that once I zero (motor as reference) and then turn the logger 180% on the motor (LCD front is now in the back)the logger reads a full degree different.Any body else have this going on?I have followed to the letter the work instructions for calibration, and have taken the battery's out and replaced with new ones. I also tried this last night on a friends slate pool table. After calibration and turning it 180 degrees same spot same reference it is still a full degree off.Curious?Mikey D |

Think of it this way... If you zero the logger on something obviously not level, say 10 deg negative slope, and then turn the device around it will read 20 degs. Why? Its reference is -10 deg slope as "zero." Turn the device around and it is now on a +10 deg slope which is a 20 deg difference.- John |

You will only get zero both ways IF the sensor is installed perfectly in the device (or the calibration routine is robust and can account for any sensor installation issues) and IF the surface used to zero the logger is exactly, perfectly level.Are you doing the full calibration on the pool table surface? Back to the Heli. If I reference my motor as zero, and I know the Heli is level, and my swash is level I would expect to see zero on pitch gauge. If I turn the blades 180degrees I would expect the same not a full degree off. What am I missing? John |

Appreciate your perspective. I'll keep working with it. It's not a big deal, in the end it's how the Heli flies.The pool table is flat because I referenced it with 4ft level. My friend tells me the installers leveled the tables when it was received as well.BTW, I have a message out to RC Logger as well. |
