RAW580 Spirit GTR 3.4.2 GeoLink v2 1.3.1 Return to home altitude set to 10M When activated it moves more smoothly to the x-y location But the z (altitude) seems to ’hunt’ It goes to 10M ish and then up 3M down 6M then up 5M down 4M up 3M (oscillation) above and below the set point finally settling down after several tries 3.4.1 and 1.3.0 did not do it Also occurs with altitude hold now

Started at 80 Decreased to 60. Same issue Decreased to 40 same Decreased to 20 lowest possible.. same Seems to affect auto land also As I used to run at 80 when 100 was maximum I set to 120 which is 80 percent of 150 ish Same wandering |

Covering the laser with a little piece of tape worked for me. I think it keeps switching from the barometer to laser sensor and you get that up and down. |

Thanks ... will try next flight looks like there is a second thread regarding the same V2 issue Regards, |

I suspect that is something to do with the FW 3.42 ! Since that the Heli not flight clean in P-Hold and R-Home ! Before in 3.41 was a clean flight. I think is not the V2 ! cwdrew wrote: Thanks ... will try next flight

At the field Downgraded to 1.3.0 Z axis still very unstable Installed 1.3.1 and covered laser with opaque label Much better… xy always was good z not using the laser +/- 1M Flying ok again with laser covered Thanks everyone |

That's funny and I hope Thomas know that , with the malfunction of the Laser. He will have a solution very soon, no problem. cwdrew wrote: At the field

Hello, covering laser opening will cause difference in airflow in the enclosure. Airflow difference will cause different pressure readings. Laser will not change behavior above 1 meter at all. So the difference will affect barometer and all changes are very likely result of this. We are trying to find what could be different, because for the most pilots we found the latest 3.4.2 helpful. Because of better weather we can do more testing. So it is possible that next week we can have new update with additional improvements. GeoLink 1.3.1 update is recommended for all in any case. |

Yes it's strange as I mention before, the Heli with 3.41 and V1 was all fine, with the update to 3.42 comes the moves, and not only with the V2. By the way, I observed that our Flying Friends flight much more with confidence, and Risk a lot of more than before, already save a lot of Helis from a brutal crash !!!! ZeXx86 wrote: Hello,
