I generally power up my electric helicopters on a 3ft high table. Then I take the helicopter to the take off spot on the ground. I would like to reset the altitude to 0 feet at the take off spot on the ground. How do I reset the altitude value to 0 feet at this take off spot? |

My understanding is the heli will reset by itself to zero when it detects vibration when the motor starts. So zero at every spoolup. |

Hi John, yes, should be exactly like pking wrote: i do have the same situation (even more as starting location is a bit lower alt on the field), see spoolup log attached >> close to -2m on startup of the heli (logging starts), height jumps to 0m during spoolup of the heli (before takeoff). seems to be based on vibration level >= 3 or similar.

why do you need to bring to 0? what function wants 0 meters precise? what is your purpose after you have 0 degrees precise? if not is accurate what could happen? |

I am no aware of any particular function that "wants 0 meters precise". . franz88 wrote: what is your purpose after you have 0 degrees precise? No "purpose".

I would expect the altitude readings to be off by the initial altitude error reading at baseline. |
