QW757 Stall in climb

very hard to know what is causing your exact problem,

I myself have been flying with the qw757 for around 3 or 4 years now and I have never encountered this..

it may sound a stupid question, but is your aircraft fully updated with the Quality Wings SP3.


if you could post some screen shots of your aircraft panel main the autopilot panel so I can see exactly how you have it set up.
or head on over to the quality wings support page
