Sorry guys, just blew it up... somehow.
Not sure what happened, I was climbing at 290KIAS and 2500fpm, the next time I checked the airspeed was 340 and increasing fast, I did not manage to get it back down in time.
It's funny because it did not look like a sudden wind change, I "felt" nothing just the airspeed going wild. So I may be responsible for this after all not the weather.
Trying to do better next time ( better than this should not be hard

)
