Hi,

I crashed my XL Power 550. I lost power and control.
I've got log from the Spirit unit.
There was such suspicious statements:
07:00 Received Frame was Corrupted
13:20 Receiver Signal Lost
19:30 Power Voltage is low

I don't know how to understand the logs, because the crash happened about a 30-60 seconds after start, and the log is 19:30 long.

I rebuild the heli and yesterday I had similar case. Fortunately, I've got control after a second. No crash, but also.... no log.

Could you help me to understand what is going on, please?

I've checked electric connection between the tail tube and the body. There is connection, so probably it is not electrostatic issue. The ESC didn't report any problem too.

Best regards
Piotr

My log issues experienced were not the same as the above, so removed the text from here. Thanks Tomas for letting me know. Dave

Hello,

if you can see Receiver signal lost error, then it mean that the unit is not receiving any signal from receiver.
So at this moment it is not possible to control the model. Also at that time failsafe mode is triggered (if programmed).

If your log is longer than duretion of connected battery then the log was from other flight (or testing on the bench).
The log "from previous flight" is not overwriten until you will view it.

In any way if you are not turning off your radio before model is turned off then there should be never Receiver signal lost event.
So definitively it is very bad condition and you should not lift off with the model until problem is found and resolved.

This has nothing to do with your settings or firmware. This issue could be result of poor signal quality between radio and receiver or signal interference. There are few possible reasons such as damage of antennas in the radio or receiver (e.g. cut antena by carbon frame) or by static discharge which is common on helicopters with a belt driven tail.

HeliDave: The issue you are describing is very different from this one. So it is better to not post in this thread to make it more clear.

Thanks Thomas,

Is it possible, that I lost controll again (I did) and it is not recorded as a new log?

Best regards
