Spirit System

Ok, let me sum all of what have happened to provide the most information.

In maiden flight, with V4.0.0, had incident with the drop in the Throttle Out that caused the cutoff (please refer to first picture of this thread).
In addition, I noticed the Throttle Out was not correcting in the Real Time Logging.

Back home, I installed V3.7.2 to see if the cutoff issue was caused by V4.0.0.

In the next flying session, with V3.7.2, had the cutoff incident in each of the two flights I made that day.

Then, I came to you. You recommended to try S.BUS.

Installed V4.0.1.

In the next flying session, first flight was with S.BUS. No issues during flight.

The second flight was with S.BUS2. There were glitches in the tail as soon I took off.
I couldn’t extend the flight with S.BUS2 as it was dangerous. I don’t know if the Throttle Out drop and subsequent cutoff was going to happen with v4.0.1.
Then, connected back to S.BUS.
Flew three more flights without issues.

I hope the information helps.

I believe we found the issue and resolved it. It could happen in some cases when using RPM sensor/Governor and SBUS2. We are doing more testing to be sure now.

Good! That’s very good.

Many thanks for your support.

Were you able to replicate the cutoff and the tail glitches?
