I did a search first and didn't see anything about this, so I'm going to ask here. I fear this post will be in vain because I didn't fully see exactly what the warning was, but yesterday as I was flying around, I was full stick forward so I was going maximum speed I suppose. Some text in the form of what I assume was a warning appeared on my FPV for just a second or two, not long enough for me to really catch it all, but what appeared to be "maximum thrust", or "Maximum forward thrust", or something like that. Like I said, it was just too quick for me to quite catch it. It did not affect the flight or control in any way. I continued the flight and landed safely a few minutes later. Has anyone else seen a warning like this, and can you tell me exactly what I saw? (or almost saw).
