Well found, I tested it and it happened to me too, But for me, the pitch is stuck at 45°.

Probably pitch stuck at value at the moment when fail happens so it may differ for each test fly.

but he can't be the only culprit, it would be interesting to know where else it comes from, spark plugs not cleaning?

In this short clip I am losing power without the pitch changing?

This still match what happened to me, if you look you will notice rapid ATA drop, but governor does nothing still pitch remain unchanged so rpm drops. Something weird going on here

Go back to my video and scroll to 4:20 and watch it  closely i disengaged MW50 and after 1 s it happens exactly MP dropped even more and rpm dropped too 

It looks like complete engine control unit major failure, what is causing ATA drop i have no idea at same time governor stops working too, let assume that it is engine loosing power due to cooling issues but why suddenly governor stops working, everything lead to MGB unit for me.

I will try and review shortly, please keep adding tracks if you have more, thanks.

I am doing cooling system damage testing on the Dora so I can look at this as well.

Thanks for all the help, this seems different than the old mystery bug, seems to have been introduced with the cooling system, but it is reported now, and I will stress how important it is we get it fixed a little faster than the previous one.

Dear all, a new fix has been requested for merge for this issue, hopefully it goes through testing ok and will be in the next patch, I am very sorry this happened again, the Dora deserves better. It was a different issue, but regardless I am hoping it is once again fixed, again, thanks for all the reports, tracks and especially the patience!
