Re: RTH FlyAway

Hello, we make our Test flight this weekend disconnected the HW Fan, but it was not better.
We already know this ventilator issue more than a year ago.
By the way, can you please recommend us Ventilator for HW that not interfered on the Spirit,
why you not offer this ventilators in your Shop ?

it is very important that there is no ESC fan from the HobbyWing on your helicopter. This is what you said is on the model.
When there is ESC fan then half of the features might not work properly in the Spirit unit, because unit thinks motor is running as it produces a lot of vibrations.
GeoLink and also Spirit unit is for example also starting logging depending on this measurement when motor is on and off depending on vibration level.
And it also calculate lift off altitude. So if you are using the ESC fan then it is unable to measure lift off altitude and then all functions such as Altitude Limit, RTH (altitude maintaining) or Auto Landing will not work properly, because it can`t know where 0 meter altitude actually is.
Altitude Limit and all GeoLink altitude functions are based mainly on GPS/GNSS measurement so it does not matter if barometer is imprecise or precise. However it use 3 different altitude readings from different sensors to be very precise. But none will work well if there is no moment when model is calm - If Vibration Level is not 0% before motor is started.
But there is another Barometer in the SPIRIT GT![]()
Also if you are using the ESC fan with so high vibrations then GeoLink and Spirit unit logging will not work correctly too.
HobbyWing and some very cheap ESC fans are unfortunately not balanced and are producing vibrations like a running motor.
You can check the Vibration Level in the RealTime logging or telemetry.
4ds files carry only settings of the unit, but Spirit GT and GTR can record thousands of logs from actual flights. If you can provide them then it is possible to see what the unit see.
Altitude Limit should engage faster than what is set in case the model is flying fast, depending on how Triggering Acceleration parameter is set. So it can engage in 30 meters instead of 20 meters for example to avoid crash in high speed. Because in high speed model require more time to recover.
Looks, you not understood my description.The model was not flying fast anny time by activation of the RTH function, it was all the time Hovering on all the RTH Test's.
Dr. Fleming: It seems that all your problems could be caused by this, because for you also RealTime logging does not work properly which is clear sign that something is wrong with the ESC fan. So if you are using ESC fan, please retry it without ESC fan.
