I am having a problem with logging and RPM telemetry with a new Spirit GTR in a new XL700 Specter VB1 build. In my Jeti DS-12, I get all the correct telemetry except for random dropouts of the RPM telemetry. I have attached a portion of the Jeti RPM log. All of the advanced logging in the Spirit unit seems to be corrupted. The telemetry is all over the place. I have attached a screenshot of the altitude log. The other logs are similar. The telemetry being sent to the Jeti seems to be correct. There is accurate altitude data (and other channels) in the Jeti log.

I don’t know if this could be a set-up issue or if the unit may be defective. The model has only 4 flights on it with hovering and slow forward flight but flies well without any indications of issues. I have another GTR in an Oxy 5 and it does not have any telemetry issues. I have gone over the wiring on both models and everything seems correct.

Any help regarding what could be causing this would be greatly appreciated. I am also attaching the Spirit unit logs and the Jeti log from the first flight.

Here are the log files.

I got a break in the weather and was able to take the Specter up again. I had noticed the vibrations were high in the last flights so I balanced the blades. The mains were good but the tail was a little off. The logs are still gibberish. The vibrations are better but still high so I will do a vibration test next and see if I can get them down.

I got another break in the weather and got the vibrations down as much as I could (to 8% across the flight). The logs are still useless. I'm leaning toward this unit being defective. I'm going to post in Helifreak to see if any one has had a similar issues as it looks like I am the only one with this problem here. If I can't figure it out, I'll attempt to return the unit.

Hello,

please try to check only Altitude for logging and then clear all the logs.

I reset the logging to only log Altitude then cleared all the logs. Attached is both the FBL and TX log. It is more readable but goes from -1000 to 5000 units.

Hello,

it looks like your unit could have some issue with the pressure sensor. If your other unit does not have this issue then I am afraid the easiest will be to replace it. We can send you new unit.
Readings must be always perfectly stable, at least of this variable.

The GTR is my Oxy 5 gives accurate readings specifically altitude. I am anxious to try the Auto Rescue feature but was hesitant with the altitude readings of this GTR. My first impression was that I would have to replace it but I was hoping there was a "magical" software solution. Lol. Thanks for the help.
